About the JTAG hardware, the USB/PCIe-to-LPT-to-JTAG usually don't work in Windows (works under Linux though, since Linux features an unified abstraction for every form of LPT port and do not allow raw hardware access,) but a direct USB-to-JTAG converter can work in most cases, although those are usually not that cheap as the LPT-to-JTAG ones. BusPirate by Dangerous Prototypes is a pretty good USB-to-lots-of-embedded-ports adapter and JTAG is among its supported port list. I don't have one though. More professional tools include U-Link, J-Link and USB Blaster, which are development tools for ARM platform or CPLD/FPGA, can also be used as a generic USB-to-JTAG adapter with supported software like OpenOCD. Last but not least if you have an Arduino or Teensy (or the like) you can create your own (or use someone else's open source code) USB to JTAG hardware. I had a bit of personal experience on using the USB Blaster (a JTAG tool for Altera CPLD and FPGA) in OpenOCD to debug Raspberry Pi (ARM-based) over JTAG. The similar can be done if the software supports whatever USB-to-JTAG adapter you have. OpenOCD can be a good starting point as it supports virtually everything.
I have to give you proper credit for this one. Not many people will try to save an old router like that one. I use DD-WRT myself and have had decent luck with it. The only downside being that one time a flash failed. Being a more expensive router, I did JTAG it back to working condition much to the owner's surprise as he didn't ever expect it to work again. You see it was his lack of patients that bricked it in the first place. Fun stuff and good information.
gotta love those little blue routers, i actually had a WRT54G back when they were new, it was used until the internet device count at my home was too high for it to handle and we ultimately had to get a new router, then not too long ago i picked two WRT54G routers up at goodwill's Buy The Pound store, one of them already had DD-WRT on it, i plan on installing DD-WRT on the other *edit* one was a v6 one was a v8 the v6 is the one that already had DD-WRT on it
I know far less about this than you do, but it all makes sense. When you ran the JTAG utility it looked to me as if you were running it in DOS, do you need to run it in real DOS or can you just use a command prompt in Windows or another operating system?
I wasn't all to worried of completely trashing it but at the time I figured this would be the hardest to do. I have done the "pin short" method on many things with varied results. That's why I attempted it. But I think I'll stick with JTAG and the such. Thank you for the reply.
I remember JTAG flashing a v1.1 or 2.0 WRT54G in about 2006. Even then it was difficult because the parallel port was obsolete so it was hard to find a PC with one and the old software to install the JTAG parallel driver thingy didn't work on winXP and the community for it had been dead for a couple of years. In the end I swapped the driver file with a LPT printer's and restarted the "printer" driver.
Legacy ports are indeed awesome. USB is fine for mass produced stuff, but it's pretty inaccessible to the home electronics hobbyist. Serial/parallel ports are simple and easy to work with, the project in this video is a good example. Also, many older high end accessories are available dirt cheap nowadays that use these ports. Shopping for my motherboard was slightly complicated by the legacy ports issue - can't take them for granted anymore. Luckily it wasn't too hard to find what I needed.
you have no idea how awesome ddwrt is it is scary as hell dong it your self for the first time but once its on your router you will never regret it its awesome
The router you have did the same thing mine is. Blinking power and solid LAN and Internet. I had it opened and tried every method including the shorting method. But no luck so I am going to try this. I was getting ready to set it up as a pay-for-use AP. Then noticed it was bricked.
I never knew such things were possible! I had a similar router that worked well for a few years, then just started constantly crashing. I ended up replacing it with a newer D-Link with wireless N. I think I still have the old Linksys somewhere, might be an interesting project to see if I can make it worth keeping, if for no other reason than just something to do.
heya, just wanted to say that i enjoy your videos and thanks for the info in this one. im just wondering where you got that jtag program from so i can get a copy of it myself. thanks and keep up the good work.
oh nice, . would it be to much to ask if i might get the contact info or website that i can get it from? i see this as a very useful tool to have in my collection just like your self. :)
This is rather interesting. I didn't know that linksys routers in this series could be modded. Not that I'll ever want to mod my linksys. It's been working happily for several years now.
Just wondering Bill how the heck can you really break your router while using a JTAG program fiddling with the CPU/RAM etc? I thought that was only software and the worst it could do was delete your RAM how can it possibly wreck it couldn#t you just re-firmware the memory?
Hi Bill, many thanks for explaining and sharing this de-bricking info, please help: I have a bricked linksys wrt54gl. I have purchased the cable and software from eBay, dismantled my router, soldered the pins, installed the software and driver as per the steps, attached the router to the correct type of port on a PC. Once I run the software though, a DOS type screen flashed up for about 1 second and then disappears. The firmware fails to load and the modem remains bricked. what am i missing?
I have an old Linksys WRT54G, and I want to know if it's possible to use it as an access point (for a computer with an ethernet card but no wifi card) as opposed to an interface for a cable or DSL modem. Far as I can tell, it looks like I need to flash it with new firmware, but I'm not certain on many details. I would much appreciate some advice.
cool, i have had a couple of different model's of linksys routers. on of which the factory firmware was so bad it would crash about once a week. i think i still have one somewhere. because i too hate to throw stuff away. i should get it out and flash it. i use a newer westell that works great with lots of features.(unlike some older westell's )
Just curious, do you do this for a living? Reason I ask is I do not have a computer with a parallel port and wondering how much you would charge to do this on my router?
hey bill, good job as always. I like tinkering with computers and I find your videos to be very helpful. If you get a chance I would love to see more computer vids. thanks
Hello sir, i have wrt54gl v.1.1 install with openwrt. But i accidently click something in 192.168.1.1. Not My wrt54gl router cannot connect to LAN. When power up the router. Power LED blingking fast and 40-60sec DMZ LED light up. And Wifi LED light up. But for LAN it never work. I cannot connect to router anymore by ethernet. Any how can i fix this. Maybe you have experience like this problem?
I have the same thing you did with your router... i run the scrip of wrt54GS on wrt54G to expand memory to 16MB. I can try jtag but is it 100% remedy in that case.. secondly do i need to sold anything on board as i have never done solding and i am quite new to it.... lastly after clearing the erom do i need to put any firmware of it will default show dd-wrt rolling back all other changes... thanks for you answere it will be really needful
um... uxwbill how did you make your jtag adapter i been looking around to find how to make one but i cant find a thing. any help would be greatly appreciated.
Hi there my friend! I have a simple question, i bought a linksys wrt 1900ac used in California but like new, I use it in Puerto Rico and no matter what kind of reset i do it shows Me that I'm in California what can I do!
I still have a old Linksys WRT54G that has DD-WRT and the OS will not boot I am going to have to take a look at the board and see if it has a JTAG on it I don't remeber and I also have a Linksys WRT54GS and in the DD-WRT says for memory Total Available 13.5 MB / 16.0 MB Free 3.6 MB / 13.5 MB Used 9.9 MB / 13.5 MB I got the WRT54GS from a yard sale for $5 US.
@uxwbill Thanks for a fast reply. Yes I have done a little more reading and it sure is a parallel connector. Thanks! Bad thing now days on laptops they are gone, it's good to keep and old one running XP with these ports.
Nice, I need that lol... but do you know much about using tftp to flash a wrt54g? I hit the continue button to early on the GUI flash and bricked it... the dmz light still comes on so they say I should be able to tftp flash it. I pinged it and I get a response so this should work but I can not seem to get the tftp software to work... when I type in tftp commands into cmd it says that tftp is an invalid command etc... any tips?
@uxwbill oh ok i use an netgear wpn824 as my wifi hotspot then i use wired from my smoothwall box to an gigabit hub that links on to all my computers. The only router i found that did the trick is smoothwall. its hard to find stuff that works well on 100mbits fiber optics. im ganna sell some of the older drives and do like you said add bigger ones. That would also work out grate :) and also more silent :) i would like to get hold of one wrt54gl and try that one out and see if it could work :)
Wow floppy disks takes me back . I am luck I have 2 wrt54g ver 2 3 the ver 2 and it is 32 meg I have heard you can flash it and open up 64 meg on ver 2 and 3 but I am not sure on how to do it.
I have a linksys wrt54g ver.2 that powers up but has no wireless activety and i can't access the setup page. Do have Any idea what's Wrong with it ? I have tried a hard reset but it did not help.
Oh wow, now that's something, although I doubt I would attempt something like that, mine works fine for now! It would probably be something id consider with an old router laying around, though...
can I do the same wit a Linksys e3000 is happen the same only the power light is working and the Linksys assistance want me to pay 45 bucks for upgrade firmware ,well that's what they told me
@uxwbill you should stress this out to check out the firmware's site to see how to install the software and to see if it is compatible, so you don't get yelled at by their's being bricked. like ddwrt = dd-wrt .com/site/support/router-database.
you should make it your style to also be a bit more careful handling such components......btw there is also a unbrick method which involves shorting circuiting two pins on the motherboard(i had to do it like 3yr ago), for those who don't own a JTAG adapter.
uxwbill what is the best affordable used router that I can I buy to extend my network via my main house wireless router to my guest house via cat cable to a second wireless router? Would that still be a Buffalo or?? I had a Linksys wrt54GS but yes bricked it so I am done. There are a lot on ebay already loaded with DD-WRT that are pretty cheap but not sure what to get? Help pleae. Thanks
uxwbill thanks and let me give you a little more background on my setup. In my main house I currently have a NETGEAR WNDR3700 wireless router form one of the wired ports I have it connected to a Cat5 that goes underground to out 700 sq ft guest house currently connected to a Blue-ray player with Netflix which makes it work much better then the week signal from the Netgear 3700. I want to be able to wire devices or use the wireless for ipad or laptops etc. so yes would like faster even know my DSL is only about 1.5 What do you think would work best for what I am trying to do? Add a Buffalo (if so which one), another Netgear 3700 or can the one I have be altered for longer range (if so how)??
hello sir i have some issues with mine and its a wrt54gsv1 , i was working with cable modems for a long and my wrt54gs , well i adjusted a setting in ddwrt and it bricked my router , will when i used my modem jtag on the router i would read the bcm chip but not the flash, its like the dos program wont read my perellel port for what ever reason but as i stated be for it reads it in toms utility.. ive been askng on forums and get no answer...
Anyway u can help me fix mine??..The power light just keeps blinking,It was working fine n all i did was raise the over clock to 250 n it stopped!!,,let me know if u can help...thanks
Hi uxwbill or other users with the info. what's the name of this 3rd party fw? we have a old linksys router that's same or similar model I'd love to play around with.
Cool have to do some Google searchs. Yeah mines the wrt54g version 6. Speaking of routers. Thanks to the never used dlink dir 628 I finally found I've built a closed( is that the right term for a network with no Internet access?) Linking my 4 inspiron laptops for funs and convenience of sharing two usb hard drives I use between them. One is veres files of mine and downloaded stuff, the other is my mp3s. I love the share point usb port on this thing, even works with a ac powered usb hub so can use multiple devices at same time. I've yet to overwhelm the ports bandwidth, believe I tried with my music hdd and a external dvd burner playing a music cd a usb hdd and a flash drive all accessing at same time. Only thing left is a KVM switch and the network switch I've ordered to get here. The switch is for expansion, I'd like to run a cable over to my bed so I can use the shareport from there. All machines are lan line all cat 5e cables.I rather not trust the wifi plus one machine no longer has a wifi card. I'd say for my first network I did a good job if I do say so my self lol.
The WRT54G routers where were all of the alternative firmware began. Linksys initially utilized open source software components in the production of these routers and unlike a lot of other hardware vendors -- they actually complied with the General Public License and released the source code. It didn't take long for people to start modifying this code and adding features to their "little blue routers" that were normally available only on units costing hundreds or thousands of dollars. For whatever reason, Linksys eventually stopped taking kindly to this and switched the WRT54G versions 5 and higher to a proprietary operating system. To further frustrate efforts to run any other software on these routers, they cut down the ROM and RAM size so the old software wouldn't fit. The joke was ultimately on them -- their proprietary firmware ran out of memory, crashed all the time and it didn't take too long before the community driven efforts made their software small enough to fit these routers. If you look around you'll see reports that the WRT54Gv5 and up aren't really "recommended" for use with DD-WRT. The various other open-source firmware projects may not even support them any longer. However, it has been my experience that the V5/V6 series routers run just fine for the average Internet user with DD-WRT loaded. It's certainly saved a fair number of them from the trash can. Putting DD-WRT on the WRT54G routers is pretty easy and straightforward. Just make sure you've got plenty of time, and that you've downloaded and printed all of the materials you'll need *first*. Your USB storage devices would perform much better when attached to a computer: you're limited by not only the speed of fast Ethernet (~12.5 megabytes/second) but also by the overhead of USB and the limited resources of the router's processor. Indeed it is convenient, and if you're happy with it, that is the only thing that matters. A network that doesn't connect to the Internet could certainly be considered a "closed" network. It can also be referred to as a private network.
+uxwbill Huh I didn't know that about linksys. I wonder what changed their minds about the open source OS? money I have no doubt lol. Another reason to be unhappy about my desktops bad caps killing my plans to reuse it as a xp/7 machine for my old games and such. another idea would to turn it into a network storage device. but that's alright despite what my old man thinks I'll be hanging onto it for future repair and revival. Perhaps it'll end up a part of my little network yet. Private network sounds better doesn't it? ya I'm pretty happy with the usb drives as is. sure a better mbps speed would be nice, but it's handled my best efforts to overwhelm the thing thus far. I was just plugging them into whatever computer I was on up till now, but that doesn't work to well whan setting up on my bed. I've almost had a few drive oops a few times already.
+uxwbill Well I tried it and I broke it... No idea how I followed the instructions to the letter, but apawn flashing the new firmware boom the all the lights go out even the power light. No it wasn't the ac cord or outlet the laptop I used wax on the same outlet. All I know is the AC is good but nothing is lighting it up not even the power light. We were having a lot of trouble with that linksys router in the last days of use, so I can't help but wonder if something was wrong and or dieing on it and the flash finished the job. Any thought oh wise UXWBill?
good save. the best bet is to load ddwrt for the model and revision number and forget about the memory. eventually the memory issues will be resolved in later versions. i turned my 40 dollar router into a three hundred dollar monster.!!!!
***** i could easily get an old printer cable for free or nickle n dime that shit online,dude come on i like your videos,sacrifice one of your precious printer cables to show people how to do it l33t mode without having to necessarily buy anything video idea submitted
I have had issues in the past with it and all I do is use windows tftp set to 99 retrys and hold the reset button doing power cycleing and 30 30 30 resets till the unit picks up the loader before it loads any flags
I failed to upgrade to a newer version in DD-WRT on my Linksys Wap54g through Web Interface. The first upgrade from Linksys to DD-WRT through "TFTP client" was successful. Now again uploading DD-WRT through "TFTP client" but it was unsuccessful. I have hard reset the device but am confused in selecting the IP in "TFTP client". What IP should I use 192.168.1.1 or 192.168.1.245? I am getting Ping response at 192.168.1.25 at the same Static IP
@@joered9796 tienes que hacer reset del router antes de usar tftp client, resetea el router a su estado de fabrica y usas la direccion ip original por que si lo haces con una direccion ip distinta cuando ejecutes el tftp client al momento de iniciar la instalacion el programa trabajara con la busqueda de la ip de fabrica pero si tu dejaste una direccion distinta y accesaste a el por otra doreccion perdera comunicacion y quedara brikeado (blokeado)
Hi, I forgot my Linksys WAP54G V3.1 DDWRT password....... and its not resetting with physical rest key............ please help me what to do..... Udaya....... India
DD-WRT is the BEST firmware on the planet, I upgraded my piece of crap dlink a few months ago, unfortunately I parted with it recently due to a superior all-in-one device.
I just wanted to apologise for what I wrote the other night I will not unsubscribe or anything I miss read your comment ik u weren't rude could u please forgive me
Routers are special purpose computers that run programs to route Internet traffic and provide security features like a firewall. Those programs utilize RAM just as the ones on your computer do.
About the JTAG hardware, the USB/PCIe-to-LPT-to-JTAG usually don't work in Windows (works under Linux though, since Linux features an unified abstraction for every form of LPT port and do not allow raw hardware access,) but a direct USB-to-JTAG converter can work in most cases, although those are usually not that cheap as the LPT-to-JTAG ones.

This brings memories back...
Did you have to use any hand or power tools for this debricking operation?
I had no idea you could do this to routers, this is a great video thanks!
Nice explanations you did there, staight to the point without missing anything -- at least not that I could think of.
hey bill, good job as always. I like tinkering with computers and I find your videos to be very helpful. If you get a chance I would love to see more computer vids. thanks
Is that connector on laptop and cable not a RS232 Serial DB25? Not Parallel...
I contacted a guy today about buying a WRT54G router with DD-WRT already on. Hopefully he responds.

I'm curious do you know if ANY version of WRT54GL isn't compatible with Tomato? I think I'm good but you clearly know more than I do however lol.
Can you use a tftp server like tftp32 to unbrick one of these? I had to unbrick a Netgear WRG614 yesterday using tftp. Does it work on a Linksys too?
I have the same thing you did with your router... i run the scrip of wrt54GS on wrt54G to expand memory to 16MB.

Used 9.9 MB / 13.5 MB
I got the WRT54GS from a yard sale for $5 US.
Which do you think is the j-tag port? (CONN1 or J5).
did you use vxworks killer first then install dd-wrt micro?
@uxwbill Thanks for a fast reply. Yes I have done a little more reading and it sure is a parallel connector. Thanks! Bad thing now days on laptops they are gone, it's good to keep and old one running XP with these ports.
any recommendations for a good reliable usb jtag cable for those of us who no longer have serial ports on out desktops ?
Nice, I need that lol... but do you know much about using tftp to flash a wrt54g?

Hi there
congratulations you are really sound knowledgeable of what your doing ,
keep it going
gracias!
Would a pci parallel/serial card work? There not too hard to find.
can you make a video on how to install the jtag software please, im stuck on the software part.
Where did you buy the JTAG tool?
I have a Jtag but its 2X5 pin total 10 pins, and the writer and reader is with a usb
any feedback?
eBay. You may have found a serial port, and not a JTAG connection. Some of these devices have one or the other, some have both and a few have neither.
Wow floppy disks takes me back . I am luck I have 2 wrt54g ver 2 3 the ver 2 and it is
32 meg I have heard you can flash it and open up 64 meg on ver 2 and 3 but I am not sure on how to do it.
I like tomato over other like openwrt or ddwrt. So easy to use and packed with feature. I have Linksys 54WRT v4 and it runs perfect with tomato.
wow, im just getting to watching this video. nice work.
What's the point in putting third party firrmware on a router?
I still own my first router. Exact same one. But it's worn out. I put it back in it's box and stored it. I don't know what I will do with it.
ok i go the driver fixed, you used the command:
-erase:nvram /noemw /nocwd
is that right?
all that does is erase the ram? doesnt in stall anything?
Impressive work, sir!
I have a linksys wrt54g ver.2 that powers up but has no wireless activety and i can't access the setup page. Do have Any idea what's Wrong with it ? I have tried a hard reset but it did not help.
Oh wow, now that's something, although I doubt I would attempt something like that, mine works fine for now!
It would probably be something id consider with an old router laying around, though...
what kind of cable I need can you tell me please and if you can give the page in ebay to buy it. thank you
can I do the same wit a Linksys e3000 is happen the same only the power light is working and the Linksys assistance want me to pay 45 bucks for upgrade firmware ,well that's what they told me
whats with the Ethernet activity lights flashing on the laptop when nothing is plugged in ?
@uxwbill you should stress this out to check out the firmware's site to see how to install the software and to see if it is compatible, so you don't get yelled at by their's being bricked. like ddwrt = dd-wrt .com/site/support/router-database.
you should make it your style to also be a bit more careful handling such components......btw there is also a unbrick method which involves shorting circuiting two pins on the motherboard(i had to do it like 3yr ago), for those who don't own a JTAG adapter.
can you make a video on how to make you wireless secure
please if possible share me the detail of SW part how to do that.... and a wiki on dd-wrt will be highly appriciated
uxwbill what is the best affordable used router that I can I buy to extend my network via my main house wireless router to my guest house via cat cable to a second wireless router? Would that still be a Buffalo or?? I had a Linksys wrt54GS but yes bricked it so I am done. There are a lot on ebay already loaded with DD-WRT that are pretty cheap but not sure what to get? Help pleae. Thanks
uxwbill thanks and let me give you a little more background on my setup. In my main house I currently have a NETGEAR WNDR3700 wireless router form one of the wired ports I have it connected to a Cat5 that goes underground to out 700 sq ft guest house currently connected to a Blue-ray player with Netflix which makes it work much better then the week signal from the Netgear 3700. I want to be able to wire devices or use the wireless for ipad or laptops etc. so yes would like faster even know my DSL is only about 1.5 What do you think would work best for what I am trying to do? Add a Buffalo (if so which one), another Netgear 3700 or can the one I have be altered for longer range (if so how)??
You have performed surgery on a Little Linksys rougher. Congrats!!
i have everything in place get a connector solded on the board and making JTAG... now i reelay need help in SW part...
where did you buy the header?
hello sir i have some issues with mine and its a wrt54gsv1 , i was working with cable modems for a long and my wrt54gs , well i adjusted a setting in ddwrt and it bricked my router , will when i used my modem jtag on the router i would read the bcm chip but not the flash, its like the dos program wont read my perellel port for what ever reason but as i stated be for it reads it in toms utility.. ive been askng on forums and get no answer...
Why do debuggers exist if you can just hook up your PC to the chip via a serial cable?
I've just shorted the clear pin on those linksys routers to get them going again.
very nice bill! im subscribing to you friend . Please continue to upload videos like this.
so what if the the router still works but the power light blinks then goes off but the router is stil working
@uxwbill its a linksys wrt54g v8 my dad tryed to make it a repeater but he bricked it lol
Anyway u can help me fix mine??..The power light just keeps blinking,It was working fine n all i did was raise the over clock to 250 n it stopped!!,,let me know if u can help...thanks
And this is why I like electronics :3
Hi uxwbill or other users with the info. what's the name of this 3rd party fw?
we have a old linksys router that's same or similar model I'd love to play around with.
This video features the DD-WRT firmware. Other options you may have include Tomato and OpenWRT. Check your router's compatibility *first*!
Cool have to do some Google searchs.
Yeah mines the wrt54g version 6.
Speaking of routers. Thanks to the never used dlink dir 628 I finally found I've built a closed( is that the right term for a network with no Internet access?) Linking my 4 inspiron laptops for funs and convenience of sharing two usb hard drives I use between them. One is veres files of mine and downloaded stuff, the other is my mp3s.
I love the share point usb port on this thing, even works with a ac powered usb hub so can use multiple devices at same time. I've yet to overwhelm the ports bandwidth, believe I tried with my music hdd and a external dvd burner playing a music cd a usb hdd and a flash drive all accessing at same time.
Only thing left is a KVM switch and the network switch I've ordered to get here. The switch is for expansion, I'd like to run a cable over to my bed so I can use the shareport from there.
All machines are lan line all cat 5e cables.I rather not trust the wifi plus one machine no longer has a wifi card.
I'd say for my first network I did a good job if I do say so my self lol.
The WRT54G routers where were all of the alternative firmware began. Linksys initially utilized open source software components in the production of these routers and unlike a lot of other hardware vendors -- they actually complied with the General Public License and released the source code. It didn't take long for people to start modifying this code and adding features to their "little blue routers" that were normally available only on units costing hundreds or thousands of dollars.
For whatever reason, Linksys eventually stopped taking kindly to this and switched the WRT54G versions 5 and higher to a proprietary operating system. To further frustrate efforts to run any other software on these routers, they cut down the ROM and RAM size so the old software wouldn't fit. The joke was ultimately on them -- their proprietary firmware ran out of memory, crashed all the time and it didn't take too long before the community driven efforts made their software small enough to fit these routers.
If you look around you'll see reports that the WRT54Gv5 and up aren't really "recommended" for use with DD-WRT. The various other open-source firmware projects may not even support them any longer. However, it has been my experience that the V5/V6 series routers run just fine for the average Internet user with DD-WRT loaded. It's certainly saved a fair number of them from the trash can.
Putting DD-WRT on the WRT54G routers is pretty easy and straightforward. Just make sure you've got plenty of time, and that you've downloaded and printed all of the materials you'll need *first*.
Your USB storage devices would perform much better when attached to a computer: you're limited by not only the speed of fast Ethernet (~12.5 megabytes/second) but also by the overhead of USB and the limited resources of the router's processor. Indeed it is convenient, and if you're happy with it, that is the only thing that matters.
A network that doesn't connect to the Internet could certainly be considered a "closed" network. It can also be referred to as a private network.
+uxwbill Huh I didn't know that about linksys. I wonder what changed their minds about the open source OS? money I have no doubt lol.
Another reason to be unhappy about my desktops bad caps killing my plans to reuse it as a xp/7 machine for my old games and such. another idea would to turn it into a network storage device. but that's alright despite what my old man thinks I'll be hanging onto it for future repair and revival. Perhaps it'll end up a part of my little network yet.
Private network sounds better doesn't it? ya I'm pretty happy with the usb drives as is. sure a better mbps speed would be nice, but it's handled my best efforts to overwhelm the thing thus far. I was just plugging them into whatever computer I was on up till now, but that doesn't work to well whan setting up on my bed. I've almost had a few drive oops a few times already.
+uxwbill Well I tried it and I broke it...
No idea how I followed the instructions to the letter, but apawn flashing the new firmware boom the all the lights go out even the power light. No it wasn't the ac cord or outlet the laptop I used wax on the same outlet.
All I know is the AC is good but nothing is lighting it up not even the power light. We were having a lot of trouble with that linksys router in the last days of use, so I can't help but wonder if something was wrong and or dieing on it and the flash finished the job. Any thought oh wise UXWBill?
@uxwbill this what happens when i plug it in the one led on the varry left is dim and thats it
good save. the best bet is to load ddwrt for the model and revision number and forget about the memory. eventually the memory issues will be resolved in later versions.
i turned my 40 dollar router into a three hundred dollar monster.!!!!
have you ever made a jtag out of an old printer cable
*****
they are not cheap if you have to justify the online purchase to a girlfriend, make a video on doing this with an old printer plug plox
***** i could easily get an old printer cable for free or nickle n dime that shit online,dude come on i like your videos,sacrifice one of your precious printer cables to show people how to do it l33t mode without having to necessarily buy anything video idea submitted
I have this router and you should have ben able to clear and replash it using tftp
I have had issues in the past with it and all I do is use windows tftp set to 99 retrys and hold the reset button doing power cycleing and 30 30 30 resets till the unit picks up the loader before it loads any flags
@uxwbill Oh, OK. i dont know much about routers. i thought they were just so you could have internet =)
i wonder if this would work with my 2wire376
where can I find this software Jtag put the link to download please
I need help getting the software to jtag my router.
oh man! this sucks because i came here because my router bricked and i didnt realize it was gonna take all this!
I see, thank you for the explanation.
Thanks for your time. :)
wikipedia has all that info by versions, yours has 16MB RAM and 4 MB Flash
I failed to upgrade to a newer version in DD-WRT on my Linksys Wap54g through Web Interface.
The first upgrade from Linksys to DD-WRT through "TFTP client" was successful. Now again uploading DD-WRT through "TFTP client" but it was unsuccessful. I have hard reset the device but am confused in selecting the IP in "TFTP client". What IP should I use 192.168.1.1 or 192.168.1.245?
I am getting Ping response at 192.168.1.25 at the same Static IP
Hi, I have the same problem, would you be kind enough to tell me, what have U done to fix Ur issue, Please. Thx...
@@joered9796 tienes que hacer reset del router antes de usar tftp client, resetea el router a su estado de fabrica y usas la direccion ip original por que si lo haces con una direccion ip distinta cuando ejecutes el tftp client al momento de iniciar la instalacion el programa trabajara con la busqueda de la ip de fabrica pero si tu dejaste una direccion distinta y accesaste a el por otra doreccion perdera comunicacion y quedara brikeado (blokeado)
can i unbrick a lineys v8?
Hi,
I forgot my Linksys WAP54G V3.1 DDWRT password.......
and its not resetting with physical rest key............
please help me what to do.....
Udaya....... India
@uxwbill dam right, my computer still has a 3 inch drive, high five
DD-WRT is the BEST firmware on the planet, I upgraded my piece of crap dlink a few months ago, unfortunately I parted with it recently due to a superior all-in-one device.
I just wanted to apologise for what I wrote the other night I will not unsubscribe or anything I miss read your comment ik u weren't rude could u please forgive me
Woo Hoo!!!
i had the same linksys router... it was rather crap i sold it. i did not like it to much it was to slow :P
@uxwbill he tryed to put firmeware on it but i dont really care about it thanks for helping =)
@uxwbill Cool!
THANKS YOU
why do routers need ram?
Routers are special purpose computers that run programs to route Internet traffic and provide security features like a firewall. Those programs utilize RAM just as the ones on your computer do.
+uxwbill never new that you learn some thing new everyday
Random Uploader same
Thank yoy
