Wifi adapter not found in Ubuntu 20.04 on HP touchsmart 600

  • 772

I searched a lot, but most of what I found is for broadcom or doesn't work.

the computer is a HP touchsmart 600 and I think it has a realtek wifi card, but I'm not sure. The wifi adapter I want to use is a usb realtek wifi adapter.

The problem is that the wifi sometimes connects but most of the time it doesn't, and once it connects it almost immediately disconnects.

I already tried everything I found and could think of, help is appreciated.
