debian8.1 已有的WIFI搜索不到
原来一直用的一个wifi,用的好好的,但就在前两天突然就检测不到了,但是实际wifi还是有的(我还有一台window的笔记本连的好好的,随便打开手机也能正常连接上网),无线网卡也是开着的,列表里有几个别的wifi信号,但是原来常用的那个却没有,真是邪门了!wifi的名字与密码都没改过,window系统的那个本一直正常使用。

Re: debian8.1 已有的WIFI搜索不到
用 iwlist scan 扫描一下试试。设SSID为TPLINK_BA1404
代码: 全选
iwlist scan | grep 'TPLINK_BA1404'

wifi里选择网络里有其它的wifi信号,但就是没有前阵子用的那一个,奇怪。

Re: debian8.1 已有的WIFI搜索不到
把下面指令 複製 貼進終端機 執行wifi里选择网络里有其它的wifi信号,但就是没有前阵子用的那一个,奇怪。
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
把結果直接 選取/複製 貼上來
