  • Bug report ID | echo $G_HW_UUID

Steps to reproduce

  1. Plug in realtek wifi adapter (8812bu or 8811cu)
  2. Nothing happens

Expected behaviour

  • Wifi should show up as a proper adapter and show up in ip list and other network tools

Actual behaviour

  • Adapter gets detected by lsusb as a proper adapter but doesn’t show up in ip list or any other wifi tools

Extra details

  • I have tried both an 8812bu (one i’m using with the native pc right now yet doesn’t function) and 8811cu (also detected by lsusb but not functional) but built in wifi works somewhat however causes errors after idling and causes frequent disconnects every few minutes so that’s why i’m trying the usb wifi adapters i have and there’s no ethernet port on the pc so i can’t just plug in an ethernet cable

probably you would need to install additional drivers for the adapter to work correctly.

What drivers would i need for example because i have the built in drivers already (8822bu and 8821cu which the former is compatible with the 8812bu adapter while the latter is compatible with the 8811cu adapter) but for some reason the rtw88 module doesn’t show up for modprobe yet the folder exists in the firmware folder for rtw88 with the firmware for both adapters ready yet currently unusable without the module installed

Here is one for the 8812bu:

Seems like i got it working using lwfinger’s rtw88 library however i can’t seem to get it connected to wifi

Yeah my adapter is stuck in down mode no matter what i do
