TP-LINK TL-WN823N dongle not working

Danish Shaikh

So I just finished doing a clean install of the latest ubilinux image (R3.0 [2016-07-07]) downloaded from here -

https://up-community.org/downloads/ubilinux/ubilinux-ubilinux-3-0

I also did

sudo apt-get update
sudo apt-get upgrade

I didn't do a dist-upgrade as I assumed that this was not necessary for this release of ubilinux 3.0.

Now the TP-LINK TL-WN823N wireless dongle does not work, and it is supposedly verified to work as claimed here -

https://up-community.org/wiki/Wireless#Verified_devices

How exactly was it verified to work?

Thanks,
Danny

Hi danishbizkit,

Have you performed an online installation with with the WiFi dongle?

If not or if you have used the wired network during the installation, please check that the Wireless interface is present on the wicd preferences page.

You can access this page clicking on the network icon (bottom-right), and from the arrow (top-right) select preferences. Then add "wlan0" (without quotes) to the wireless interface field, press OK and then perform a refresh.

Let me know if that solve your issue.

Hi dcleri,

I did an offline installation, and I tried adding wlan0 as you suggested, but it doesn't work.

DCleri

Can you please confirm from the terminal that your wireless dongle is identified as wlan0?

Open a terminal and run:

sudo iwconfig

the output should be like the one in attached picture.



If your wireless dongle is not identified as wlan0 but as wlan1 or something else, please use that identifier on wicd preferences.

Danish Shaikh

Thanks for the screenshot. I don't get any entry for wlan0. I'm attaching a screenshot of dmesg....

Which is the product ID from your dongle? I cannot see from your screenshot.

Is the one you received bundled with UP Board?

This is my dmesg after connecting the dongle TP-Link TL-WN823N:

Hi, I didn't order a wireless dongle from UP along with my board. I bought it separately.

Danish Shaikh

Is there a difference between your installation and mine or between your dongle and mine. My TP-Link TP-725N dongle works but everytime I try playing a video in youtube or starting kodi, the distro crashes....

Hi danishbizkit,

It seems the dongle you bought is v2 while the one shipped with the UP board and tested is the v1.x

The v2 is not currently supported by the Linux Kernel (at least not until 4.4). Checking online, I saw that people using with the Raspberry Pi have the same problem.

For example: http://raspberrypi.stackexchange.com/questions/49825/wifi-dongle-tl-wn823nv2-not-is-recognised

Unfortunately the manufacturers for such dongles keep changing chip/revision which break compatibility and it is very difficult to support them all.
As suggested on that page the only way is to double check online that kernel support is available for that chip/dongle.

About the other dongle you have, the TL-WN725N, you should check if it is v2 or not and try to install the most up to date drivers.

If so, you can try this tutorial (starting from line number 6):
