WiFi Dongle: How to make it work?

Help and Support Help
1

Hi all!

I’m trying to use a wifi dongle (Tp-Link T2U) on a raspi 3b+ (I have some instability issues due (I think) to the -not totally close- metal case). In the compatibility list we can read that it (Tp-Link T2U) works out of the box. It’s wrong for me: No led blinking… No led at all :imp: :angry: . I’m on the latest version of Volumio.

Here is what I get with ifconfig:

So it is recognized (Device 005).

I wanted to follow the installation tutorial provided by tp-link on their website https://static.tp-link.com/2018/201812/20181207/Installation%20Guide%20for%20Linux.pdf but at reboot the “8192eu.ko” driver no longer appeared in lsmod. After some researches I’m not sure that I have to load any driver…
Could someone help me?

Compiling the driver will have the issue that when you update, you will break your install.
My advice is: if the dongle does not work, accept it and get another one. I am telling you this because I got mad enough trying to have wifi drivers working… Found out that or it works out of the box or is not worth the pain

Argh… Ok thanks for your reply. I didn’t want to modify my player case but it seems that it will be easier for me than testing many dongle…

Since it is not guaranteed that from one machine to another a same dongle works, it might be nice to put a warning at the beginning of the compatibility list. It might save some people from getting screwed like me, and buying a dongle for nothing.

Anyway, thanks again for your reply and thanks for the work you did: I LOVE Volumio!

Why are you using a USB wifi adapter?
The R Pi 3B+ has on-board wifi.

I observed severe Wifi issues with the latest release on Raspberry with Edimax Wifi dongle.
The same Hardware runs without any issues with an older image. I test it now with a release from 2018 (volumio-2.452-2018-08-27).

Maybe it is worth to give it a try…

As just seen there is also a bug report at GitHub about that problem. Was there any change in Wifi sections?

Ok thanks for the idea. T2U seemed to work with Volumio 2.118… It’s old… But: why not?..
