Thank you very much for your explanation ! I bought one a couple of days ago to make videocalls with my portable phone by using ethernet network instead of wifi (because of interferences with neighbours), I was crazy trying to install them but no sucess ... until I have watched your video. My conclusion, it's much better to run on wifi, get approached to the router as much as possible, and live happily !!!
Hi, guys. Got the exactly same dongle in dead-cheap price. As reported, it's USB1.1 device which is supposedly identical to Davicom DM9601 USB Ethernet controller. Here is the list of abnormalities found so far. - VID/PID register contains 0x00, though chip revision register shows 0x01. Those should bring Davicom HW standard values or vendor assigned values in EEPROM. - I keep failing to manipulate PHY and read EEPROM content. The dongle works in auto negotiation mode all the time and provides no way to control 10/100 setting or duplexity. If it correctly referred itself as USB1.1 product, the seller is mostly an honest merchant. Correct USB2.0 dongle should have DM9621 and its siblings inside. Wiped VID/PID values, clipped PHY access and missing external EEPROM might be intentional act to hide its real identity.
Thank you very much. I could not figure out the slow speed - thought something wrong with my line. Will definitely request refund because reputable computer stores should investigate before they put something on the shelf.
Great explanation! I couldn't find the issue why my network drops to 5mbps and even my mobile tops to 70-80mbps on the same network via Wi-Fi. I was going to change my 10M long LAN cable if it wasn't for you. Thank you!
Thank you so much! This is very helpful!!! I bought a similar one (same package says USB 2.0 and SIV also says uses USB 1.1). I bought it for under US$1.65. By the way, in the past, I also bought other USB to LAN devices like this for the same price US$1.65 but it actually works at USB 2.0 and really has speed of 25 Mbps which is the network I use. So it is not really the price but the mis-representation/mis-labelling of the packaging. Thank you! Thank you!
@@freename The Chinese company from whom I imported 10 pieces of this is disputing that their product is really USB 2.0. Would you know of other evidence I can use aside from using SIV? As you pointed out, even Windows reports it as 100 Mbps but it really just connects at USB 1.1. Is SIV considered "authoritative"? I've seen that many other customers (on online shopping feedback) are also importing these fake products and discovering they only function at approximately 5 Mbps. But others don't know and get scammed. I import a lot of these adapters so I would like to help identify and get rid of these fake products. But I am not a computer network expert and so am not sure what other evidence I can use if people will not accept SIV's report. I'm a researcher but it seems there is very little I can find on this topic on the internet. Thank you!!!
@@andrefritzie I would say that the limited speed at USB1.1 when transferring data is pretty good proof that it is only USB1.1! I've yet to see SIV be wrong about system inforamtion too.
Any idea what's the difference between the KY-RD9700's Kontron DM9601 and the DM9620/DM9621? I've seen many USB to RJ45/Fast-Ethernet, but they use a different chipset (RTL8150/RTL8152b , AX88179/88772b, etc). I'm looking to find one based on the DM9620/DM9621 in order to compile/load this driver, qop_kernel/drivers/net/usb/dm9620 and most importantly, call one the functions in that driver: 'dm_write_eeprom_word' BTW, any suggestion how compile/load a linux driver and call a function?
Thank you for this video! It's too late for me, because I've already bought this shit, but your video saved my time, which could be wasted at my attempts of installing different drivers.
I think you're quite experienced with technical stuff so your explanation is professional and credible. I have some questions and hope you, or your viewers, can answer: (1) My old laptop (Lenovo Z480) has a built in NIC, and if I decide to buy a good USB 3 Ethernet adapter (from a reputable seller - any recommendation?), I assume it will automatically replace the built-in one. Do I need to disable the one that comes with the laptop in order to use the new one? (2) I thought most USB Ethernet adapters these days are basically "plug and play". Do we still need to stall the "driver" to make it work? (3) I plan to buy one that comes with 3 extra USB 3.0 ports on it for connecting to other devices. Is it a good idea? Thanks for answering any (or all) of the questions above. Anyone welcome to reply and appreciate it. P.S. Just subscribed to your channel.
1) It will be in addition to your built in network card. 2) Unknown, if your machine is on the internet when you plug the new one in it will likely download the drivers from windows update. 3) Yes, a friend has an Anker brand one of those and it works well.
Brilliant! I had been tearing out what little hair I had left over one of these f******g 5mbs things. I'd been a laughing stock at work when home "Teamsing" then lost my job. I had rewired the spare room and bought a new laptop, only to find now that the old laptop gets 250mbs on the new wifi mesh. This is for the bonfire. Cheers mate, £7 up in smoke. These conmen need exposing or worse.
Ah no wonder I only get 10Mbps link to my router with this. With that said, this is totally fine for my use case as it will be used on a Pi Zero for a Pi-Hole setup
@@TingFeng77 yes i am using the left port. but no internet so far. i checked it on my PC and it works after i install the driver. it also has a linux driver but apparently raspian doesnt support all linux drivers
@@gigigelashvili5416 If it doesn't work when plugged in you are pretty much out of luck. If the driver isn't built into the operating system you have no other options. As your mac is so old it is also worth making sure your new replacement USB adapter reports it works with the version of OS X you use before buying it.
@@freename well the red light is turning on when plugged in. But on mac still shows the wifi button. What to do? I do not know :( I really wanted to use this one for now
@@gigigelashvili5416 The light is just because the device is getting power from the USB. I expect the light would plug in if you plugged it into a charger too. It isn't worth doing anything with. Return the device or throw it away. There is no reason to continue to try to make it work. Its an awful and fake product and Apple computers are difficult enough to get real devices working on let alone fake old devices.
i have one but its too slow, barely has 1 mbps download speed doesnt even give 10% of my internet speed, any fix or a new driver a reply would be appericiated
I bought this device since my Windows 10 can't install the drivers.I asked to the shopkeeper if it was plug and play and he said yes because i have Windows 10, but it isn't...I lost 10 € and I still have my pc without internet... I tried with this USB ethernet adpter,tethering USB with my smartphone, but my pc doesn't show the network connections.
got a very cheap chinese MB that a buddy of mine got scammed, got his money back but didn't return it, the ethernet adapter doesnt even work, been using it for some tests and tried one of these adapters, nearly changed my switch to now find out that this usb adapter is the culprit, too bad it's kinda hard to get a pci-e x1 gigabit adapter here
actully it says usb2.0 fullspeed (which is usb1.1 market name) when you buy it, as such ,it is supporting usb2.0 but not the speed, just like almost every MCUs with a `usb2.0 support`. Personally it is a scam everyone is doing.
I have bought a KY-RD9700 as well knowning that for 2$ it would likely not be USB 2.0 but a fake. However, for ssh'ing into my embedded system (with CONFIG_USB_NET_DM9601=m) and running some scripts it actually works well.
The Content in this Video is Perfectly True.. this is a complete *Useless Product* my internet speed was down-80mbps upload-87mbps i thought using an ethernet could give me more better expereince but i struggled hard to find which ethernet cable fits my laptop's ethernet port, finally i found out RJ45 would fit to my laptop but it was quite expensive and also thought i cant return if it dosent fit to my laptop.. then i browsed online and found this product, so it converts an ethernet to an USB so on back they had written it can transfer upto 100mbps but the real part is it only for 4mbps internet connection.. what a waste i wasted time and money on this.. so i conclude this is not the right product you are looking for.. it is a fake chinese cheap product which does not even do the job.. my suggestion add some to your budget and buy a better one.. hope it helps.
i didnt expect full speed but that was blatant scamming. i don't have a cd rom in my laptop and i believed installing drivers from cd rom died ages ago . i knew something is fishy when winodws couldnt even find compatible driver and no online website for this hardware.
its pretty great i use it on windows 10 with around 6mbps on gigabit network also makes my PC gets on Bluescreen after i unplug the ethernet cable lmao

Ah, correction. VID/PID must be hard-etched. EEPROM, if ever, is to override various register contents and USB identification strings.
And I thought that DELL were bad [they are].

but the package look ACTUALLY the same as this its just say diffrent model
i've cheked it and yes ITS A 1.1 USB lmaooo thanks for this video man
well its absolutely wrong to expect something good from something cheap haha
It is a shame that these things are still being sold :(
Yes, bro, it also gives me that result and I have checked it from my smartphone. more than 6 MB did not happen
