I have a fairly old dell laptop. It used to work fine till 20.04 LTS. After moving 22.04, I started to experience problems with Wi-Fi connection. Sometimes no network, slow speed, if I disconnect and re-connect, it works for about 30 seconds, then suddenly Wi-Fi signal shows weak, then drops the connection. Is it hardware or software related? Any help is much appreciated.
