Just tried it with the r43124 snapshot and have the same problem as Gabriel. The WR841N only has 4 megabytes flash memory, and luci was a tight fit when installing with this opkg method. It looks like either the base system or luci bumped up over the limit in some recent build. One option is to use the stable release (Barrier Breaker 14.07), which comes with luci preinstalled; the other, if you're deadset on using a bleeding edge build, is to use buildroot and/or Image Generator to make your own image which contains luci. The downside is that this is a lot more involved than using opkg, and the upside is that the programs on the image are more compressed, so more will fit. OpenWRT Buildroot: wiki.openwrt.org/doc/howto/buildroot.exigence Image Generator: wiki.openwrt.org/doc/howto/obtain.firmware.generate I'll try to comment if the opkg method starts working again.
Following @Digital Creature suggestions, I tried to upgrade using the Image Generator to generate an image with LuCI built in. I managed to flash, successfully, to the latest trunk version (50082). Although this build is using a lot more of RAM (only 29% available) than the previous (~50% available), 14.07, which I had before, using the same configuration, everything seems to be working normally. Thank you so much for you video, and your tips.
Hi... I need your help. I have a TPLINK841N with openwrt... but I can update and anythink. Can I reverter the firmware?. This message in my route: opkg_conf_load: Could not lock /var/lock/opkg.lock: Resource temporarily unavailable.... What can I do? Sorry for my English. Best regards
I just bought this router and was wondering if dd wrt is worth flashing to.. I've never flashed a routers firmware but understand the procedure and have done the same thing on other devices.. I'm just curious to how much more power can I get out of it and I have a ps4 that I have hard wired to the router.. Would dd wrt make a wireless connection better for gaming or even wired?
Hi Thanks for your tutorial, I brick my router. Tried tftp and didn't work. Do you have any idea how to get this to work again? Thanks PS : mine is v9. If you could make a backup with eeprom reader I'm really thankful for you.
Javier Chapa Not sure... A quick search sounds like it has something to do with uhttpd. Try asking on the forums! There are a lot of knowledgeable people there
Hey hey, I'm a little late but... I'm unable to connect to my router after the upgrade via telnet. (Trying 192.168.1.1... telnet: Unable to connect to remote host: Connection refused) I have no idea how this even happened in the first place, can anyone help me with this? Edit: Never mind. I just SSH'ed into my router with root. (root@IP). I then changed the password from there and rebooted.
i reach upto opkg update and stuck there....help help internet is working i can ping 8.8.8.8 but when i run command opkg update it said failed to download.
Try pinging downloads.openwrt.org from the router to see if it gets through. Running 'cat /etc/opkg.conf' will show where opkg is configured to look for the repositories. If you're trying to do this on a WR841N or other 4 MB flash device, the opkg install step will run into an out of space error, as per the other comments (I confirmed this again today with r43976). 8 MB flash and higher devices should work fine.
Digital Creature there was probelm with gateway i fix it and try again but now there was no space error so i restore back to tp link firmware.. with already striped image from openwrt.org
That sounds like the internet connection wasn't established 2:40 wiki.openwrt.org/doc/howto/internet.connection Or the server might have been down at the time
Stuck on the Luci step since I didn't read the comments before trying this T_T. How do I install Barrier Breaker from SSH without the web interface? Nevermind, figured it out. Downloaded TL-WR841ND-V9-stripped.zip from wiki.openwrt.org/toh/tp-link/tl-wr841nd, ran HFS (a small webserver), and used wget to transfer the file and ran sysupgrade to revert back to stock firmware.
Eric Seto Glad you were able to get unstuck! You can also flash to other openwrt versions from within openwrt by using the sysupgrade.bin images (instead of factory.bin ones). When I do this I usually use the -n flag with sysupgrade so that my current config files are replaced with the defaults of the image I'm flashing to. This is usually unnecessary, but it avoids bugs if there were changes to config handling between the two versions.
Kris Kris I don't think that OpenWRT firmwares transmit at any greater strength than OEM ones. General system stability might be better or worse depending on software/bugs in one image or the other, and the specific device. OpenWRT's been very stable for me so far
Acacio Mello Looks like it should work: forum.openwrt.org/viewtopic.php?pid=258208#p258208 The wiki says it has 4MB flash, so if you want luci, use the BarrierBreaker image
Lakomich The normal offline method is in the wiki here: wiki.openwrt.org/doc/howto/luci.essentials#minimalistic_offline_installation But it uses opkg, and the MR3020 only has 4MB flash, so that probably won't work anymore. Easiest would be to just flash a stable image (Barrier Breaker) so that you don't need to worry about installing luci yourself. Or if you're interested, you can learn how to build OpenWRT from source so that you can create a custom image from the development trunk with luci baked in: wiki.openwrt.org/about/toolchain
hi Mal Gillies. i tell you how can unbrick your router with out serial port man you need, find firmware on iternet first after you watching case back you see over there version and model example: tplink-tl841n is my router. v11.0 version maybe you have 8 or 9 version so you know, 1 download firmware 2 Rename the bin file to wr841nv9_tp_recovery.bin 3 you need a serial bort or arduino mega 4 download TFTPD
Many thanks for the effort to put this up, Digital!
All my other routers have just been a .bin flash with LuCi included.
instructions worked like a charm! I didn't have to go through installing luci as it came pre packaged. Thanks a lot!
Without reading other's comments: it is the best instructional video I have ever seen. You are great, my OpenWrt router works now. Thank you! :-)
Hi! How to allow access to the web interface from outside? I mean access to the router over the WAN. Sorry for my english, I use Google translator.

Can I manually change mode of Ethernet/WAN ports (actually set 10Mbps duplex) with OpenWrt?
tendras algun nuevo metodo? el update no funciona en un router que acabo de adquirir
hello, i have another router with 4mb memory. i can't flash luci. how can i reflash the firmware?
Hi
Thanks for your tutorial, I brick my router. Tried tftp and didn't work.

Worked perfect! Thanks!!
Hey man, can you help me change the ttl using luci gui?
Hi, I tried the same steps but I get a "Bad Gateway The process did not produce any response" when trying to access via web GUI, any advice?
Javier Chapa Not sure... A quick search sounds like it has something to do with uhttpd.
Try asking on the forums! There are a lot of knowledgeable people there
did you find any resolution for that?
hi thx for the video. can u tell me what's the highest transmit power u can set on this wifi router pls? thx.

after login ssh using putty im not able to update opkg it shows some error and dont able to install luci
I have the same problem...
burnatoth What error does it give? If it's low space, please see my earlier comment.
It's not low space, it's says "download failed"
That sounds like the internet connection wasn't established
2:40

It was, I can navigate in the internet normally...
My Router (TP-Link 841N v9) cannot connect to the internet. How to run "opkg update" without connect the internet?
+Danh Tran Cong I had found answer. thanks
Can u please share it with us ? I'm stuck with that problem for hours ... :/ Cant find the solution.
+jozica vetrih. Hi Jozica.
The guide install LuCi offline: wiki.openwrt.org/doc/howto/luci.essentials#minimalistic_offline_installation
Good luck :)
No internet connection=no opkg update so... lama
Very useful, thanks a lot

hello, great! (sorry for my english, iam mexican) i cant install Luci, extract_archive: no space left on device.. ?
Daniel Martinez Chan Installing luci with opkg doesn't work on this and other 4MB routers anymore. Please see the other comments
Does OpenWRT extend or improve Wi-Fi signal quailty?
Kris Kris I don't think that OpenWRT firmwares transmit at any greater strength than OEM ones.
General system stability might be better or worse depending on software/bugs in one image or the other, and the specific device. OpenWRT's been very stable for me so far
Digital Creature Thanx a lot!
Thank You a lot very helpfull

Please show how to do it on Windows.
It works in TPLINK MR3220 model?
Acacio Mello Looks like it should work: forum.openwrt.org/viewtopic.php?pid=258208#p258208
The wiki says it has 4MB flash, so if you want luci, use the BarrierBreaker image
how instal LUCI without WAN , in offline ? direct connect mr3020 with notebook

hi Mal Gillies. i tell you how can unbrick your router with out serial port man you need, find firmware on iternet first after you watching case back you see over there version and model
example: tplink-tl841n is my router. v11.0 version maybe you have 8 or 9 version so you know,
1 download firmware
2 Rename the bin file to wr841nv9_tp_recovery.bin
3 you need a serial bort or arduino mega
4 download TFTPD
