USB wifi not recognized

**ionmich** · 23-Jan-2021, 17:31

Bought another USB wifi device. When I invoke

Code:

sudo lsusb

the device a tp-link WN8200ND(UN) v2.20 does not show. Running Ubuntu it is identified as

Code:

Bus 005 Device 003: ID 2357:0126 TP-Link 802.11n NIC

and works normally. Where do I start to diagnose the problem?

**ionmich** · 23-Jan-2021, 17:51

Correction. It shows as follows;-

Code:

Bus 005 Device 003: ID 2357:0126

...with no further information.

**ionmich** · 23-Jan-2021, 18:12

More information. I read somewhere that the driver rtl8192eu applied to it. This was already in place from the previous device used. But I think that is the problem. My wired connection via cable is not available so I can´t download anything.

Code:

sudo hwinfo --wlan

So what is the issue here? The output you've shared shows that driver is loaded and device node "wlan1" exists.

It connects to my destination, then disconnects after a very short time, under two minutes, and will not reconnect. When I reboot it repeats. Yet if I boot Ubuntu, it stays connected to the same destination.

Ok, this detail was missing in your opening post.

If using NetworkManager, you could observe the logging in real-time using

Code:

sudo journalctl -fu NetworkManager

then you could come back with output at the time the wifi disconnects for example.

USB power management issue perhaps? You could try inhibiting (globally) by adding 'usbcore.autosuspend=-1' to the grub kernel parameters and see whether that helpls (assuming that is the issue being encountered of course).

Please post:

Code:

zypper se -si rtl8192 kernel

Code:

uname -a

Does it work if you start with an older kernel?

ion@localhost:~>

I haven't tried an older kernel...yet. It's my last resort as I have had problems with other applications at times. I might be more inclined to using Ubuntu, which works with it, when my wired connection stops working. This is a somewhat frequent interruption in my part of Mexico. It's not the end of the world if I can't get it to work. I would just like to understand why.

The output from the second command was too long so I split it into a second post.
