![树莓派4B wifi问题](https://linux22.com/image/209973/%E6%A0%91%E8%8E%93%E6%B4%BE4B%20wifi%E9%97%AE%E9%A2%98.png)
一段时间以来,我的树莓派无法连接到我家的无线网络。它已经运行良好相当长一段时间了,唯一可能影响它的是系统更新。它有树莓派操作系统。我已检查 SSID 和密码并确认它们是正确的。 ip a 的输出:
-- snip --
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether e4:5f:01:0f:3d:bd brd ff:ff:ff:ff:ff:ff
sudo wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -i wlan0 的输出
Successfully initialized wpa_supplicant

同样的事情不断重复。任何想法表示赞赏。
