W kernelach z serii 5.x powinien być sterownik do tej karty. Upewnij się czy masz odpowiednio nowy kernel uname -r. Jeśli tak to sprawdź czy system widzi kartę ip link show. Możesz też grepnąć dmesg w poszukiwaniu mediateg, mt76x0 itp żeby zobaczyć czy nie ma żadnych błędów. W dmesg warto też sprawdzić czy nie krzyczy o brakujący firmware.

#6

No jak widać karta to: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter
a moduł do jadra to: mt76x0e
sudo modprobe mt76x0e
powinno załadować moduł i uruchomić wifi.
