다음과 같습니다 dmesg -w:

다음과 같습니다 /etc/modprobe.d/iwlwifi.conf:

실행하면 sudo systemctl restart iwd.service && sudo dhcpcd wlan0다시 작동하기 시작합니다.

이 문제의 원인은 무엇이며 해결 방법은 무엇입니까?

답변1

이 명령을 실행했는데 문제가 사라졌습니다.

sudo systemctl disable [email protected]
sudo systemctl enable dhcpcd
reboot

위의 해결 방법이 작동하지 않는 경우. dhcpcd를 비활성화하고 네트워크 관리자를 사용할 수 있습니다. 이것은협회네트워크 관리자를 설치합니다.
