ubuntu 20.04 kernel 5.11.0-27-generic about 88x2bu HOT 11 CLOSED

I don't have a clue at this point. What I do know is that these Realtek drivers do not support WPA3. In fact, if your wifi access point has WPA3 or WPA3/WPA2 mixed selected, it won't work. Make sure 802.11w is not active in the access point either. Also, I'm pretty sure these Realtek drivers have never been tested on USB3 gen2 ports so that could be a factor.

There are reasons why I started the following repo:

https://github.com/morrownr/USB-WiFi

Realtek offers no public support. There is no known way to report bugs to Realtek. Realtek does not publicly release their drivers. It has been a long time since I have been able to find a new Realtek driver at a dealer web site. We may never see updated drivers from Realtek.

My opinion is that Linux users should stay away from Realtek based USB WiFi adapters.

What usb wifi adapter are you using?

What laptop are you using?

What exact model of Google WiFi are you using?

What module parameters did you set?

Hi

Laptop is a metabox Flo, which is based on Insyde corp L140CU
Adapter is a simplecom NW632

I'll hunt out the exact model of Google Wifi, but it was the original version
I didn't change any from the install script

Try: rtw_switch_usb_mode=1

from 88x2bu.

I know the above was a little harsh. Sorry about that. A little frustration showing. I am tired of Realtek not supporting their product. We can't fix everything out here in the community.

from 88x2bu.

No worries, thanks for taking the time to look at the issue. I have raised it with the supplier, and pointed them to this ticket

from 88x2bu.

I have the same problem here, and couldn't solve it yet

@terremoth

Hi. I'd appreciate if you would start a new issue and post the results of the following in it:

$ sudo uname -a && mokutil --sb-state && lsusb && rfkill list all && dkms status && iw dev

Regards

from 88x2bu.

@morrownr I did a lot of things trying to install the driver from this repo and from others, and after reboot "suddenly" worked, I don't know if it were from this repo or from another.
If this happens again, I will do it

from 88x2bu.

I stumbled across this github issue when trying to get my Simplecom NW632 usb adapter working on my arch installation. , Incidentally my usb adapter uses the same Realtek chipset mentioned in this issue i.e. idVendor=0bda, idProduct=b82c, bcdDevice= 2.10. I managed to get the device working on my arch installation. Posting my steps here, perhaps this will help someone else.
