更新驅動程式

update-initramfs -u

查看硬體位置

modinfo mt7921e | grep alias

編輯 /etc/modprobe.d/mt7921e.conf
加入以下內容

alias    pci:v000014C3d00000616sv*sd*bc*sc*i*    mt7921e
alias    pci:v000014C3d00000608sv*sd*bc*sc*i*    mt7921e
alias    pci:v000014C3d00007922sv*sd*bc*sc*i*    mt7921e
alias    pci:v000014C3d00007961sv*sd*bc*sc*i*    mt7921e

編輯 /etc/udev/rules.d/99-mt7921e.rules
加入以下內容

SUBSYSTEM=="drivers", DEVPATH=="/sys/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 0616"
SUBSYSTEM=="drivers", DEVPATH=="/sys/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 0608"
SUBSYSTEM=="drivers", DEVPATH=="/sys/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 7922"
SUBSYSTEM=="drivers", DEVPATH=="/sys/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 7961"

如果重啟後還是沒有 wlp4s0
先執行 modrpobe -r mt7921e 之後在 modprobe mt7921e 看看是否出現 wlp4s0
