我已经构建了 BLFS 8.4，但 WIFI 无法在其上工作。开机出现错误信息
Starting wpa_supplicant on the wlan0 interface...Could not read interface wlan0 flags: No such device
Could not read interface wlan0 flags: No such device
Could not read interface wlan0 flags: No such device
WEXT: Could not set interface 'wlan0' UP
wlan0: Failed to initialize driver interface
*****
*****face wlan0 doesn't exist.
我用 wlp2s0 再次进行了配置，因为那是我的接口。现在开机不再报错，但仍然无法通过wifi上网。
的输出ip link是
bash-5.0# ip link
