[SOLVED] TP-Link Archer T2UH WiFi dongle

[SeaGull]

Hi,

I have recently bought a TP-Link Archer T2UH AC600 WiFi dongle for my Raspberry-Pi 2B, and it's not working. I have tried to install its driver (mt7610) and make it work, also following various posts in this forum but, this resulted in no success. Also, the Pi freezes frequently when connecting the dongle to it. Can anyone help, please?

Update:

- The dongle can see SSIDs but not connect to them!
- iwlist shows all the AP's available with their respective signal strengths and quality.
- iwconfig shows only the frequency, but not the SSID and other information, they are marked as ""

Thanks in advance.

IIRC, the only AC wireless dongles I've tried with Pi's required an external powered USB hub to work reliably, especially when trying to use 5 GHz.

[SeaGull]

I have tried with an external power supply, but it still didn't work. :/

[ktb]

Will you please post the output of the lsusb command? How about lsmod too? Maybe some dmesg output upon plugging in the dongle?

[SeaGull]

I'll try them and keep you posted! Thanks for your help.

[ktb]

No problem.

Perhaps MrEngman will come around. I'm sure he could make quick work of getting you up and running.

This is what I got from lsusb and lsmod respectively:

Which part from dmesg is of interest, as I'm getting a lot of information?

Thanks again.

I never got that model working properly with Raspbian, I tried several drivers.

I have had really good reliability using the older TL-WN722N model (2.4GHz only).

The dmesg output isn't necessary. The other output is good enough. mosespi may be correct that it will not work.

You might want to give MrEngman's install script a try. viewtopic.php?p=1039535#p1039535

The script does appear to have support for those Vendor and Product IDs. However, I don't know if MrEngman's drivers are all up to date and available.

[SeaGull]

That's very bad news
I have already tried @MrEngman install script, and was very surprised that it didn't work as others managed to make it work. Do you know how can I contact him, please? I really need to make it work. Thanks again for your time.

[ktb]

You can try sending him a private message memberlist.php?mode=viewprofile&u=10221

It looks like he last posted to the forum on Feb. 11th.

EDIT: And when you say the script didn't work, what did the script tell you? There should have been some helpful output (whether successful or not) when you ran it.

[SeaGull]

Thank you! It said that the driver was found (mt7610), downloaded and installed, and that I should reboot for it to start working. I can re-do it if the output helps, no problem.

[ktb]

If the script ran without errors and indicated that the driver was installed successfully, then it probably isn't necessary to try again. Sorry I can't be of more help. I don't have that hardware.

[ktb]

The only other thing I can think of which might be worth trying is using the wext driver. One of the AC dongles I have (Rosewill RNX-AC600UB, Bus 001 Device 012: ID 0bda:0811 Realtek Semiconductor Corp., driver: 8812au) required that.

[SeaGull]

That was it! Thank you very much!

So to recap, the steps to install a TP-Link Archer T2UH AC600 are the following:

1. Install the driver provided by @MrEngman by entering the following commands in terminal:

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/install-wifi.tar.gz
tar xzf install-wifi.tar.gz
sudo ./install-wifi

2. Go to /etc/network/interfaces, open and add the following:

Code: Select all

wpa-driver wext

3. Reboot, turn on WiFi and select SSID

4. Enter password (if required)

5. Enjoy

NICE! Good to see you got it working.

Hello,

I'm having the same issue with getting my TP-Link Archer T2UH USB Wi-Fi adapter to work. The link in the solution post doesn't work any more. Any chance someone could provide a working like to that file?

Cordially,

Rob

Dropbox made changes which killed my original wifi driver install script. I have a new script which will automatically determine the driver you need for the Raspbian kernel version you are using and download and install it.

Download and install the new script with commands

Code: Select all

sudo wget http://www.fars-robotics.net/install-wifi -O /usr/bin/install-wifi
sudo chmod +x /usr/bin/install-wifi

The command

Code: Select all

sudo install-wifi -h

will show details on using it.

To install the driver on your current kernel you should just need to run command

Code: Select all

sudo install-wifi

This will select the driver you need and automatically download and install it.
