poloshiao 写了:lsmod | grep rt2800, 有驱动。
把結果複製貼上來
不要惜字如金 遺漏重要資訊
把下面指令 複製 貼進終端機 執行
0. uname -r
1. sudo lspci -knn
1-1. 如果無線網卡是 usb 裝置 請增加
sudo lsusb
2. sudo lshw -numeric -class network
3. sudo ifconfig -a
4. sudo route -nv
5. sudo rfkill list all
6. sudo nmcli dev status wlan0
7. sudo dkms status
把結果直接 選取/複製 貼上來
每次插上网卡都会死机,,为了这些指令,强行关机了不下20次
感觉是驱动有问题吧,就算连上之后右上角的网络中也不显示wifi网络
一开始就是想问问 .bz2文件怎么安装而已。。重装一下会怎么样
