I have an issue after installing Ubuntu 22.04.1 on my Lenovo Legion laptop. The wifi button disappeared and I can't connect to the internet using wifi. I used the command [sudo lshw -c network] and have the line "Network Unclaimed".

After using the command [sudo dmesg | grep iwl], here are the complete error messages.
[ 3.184712] iwlwifi 0000:00:14.3: Detected crf-id 0xa5a5a5a2, cnv-id 0xa5a5a5a2 wfpm id 0xa5a5a5a2[ 3.184727] iwlwifi 0000:00:14.3: Can't find a correct rfid for crf id 0x5a2[ 3.184744] iwlwifi: probe of 0000:00:14.3 failed with error -22
Does anyone know how to solve this issue? Any suggestion would be extremely appreciated!!!!
