装了个双系统,win7下无线OK ,但ubantu下无法使用无线,只能用有线。
这个问题怎么解决一下?需要装什么驱动吗?
我用的版本是官网上的12.04LTS

Re: thinkpad E440 无法使用无线网卡
把下面指令 複製 貼進終端機 執行
1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv
4. sudo dhclient -v
把結果直接複製 貼上來
1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv
4. sudo dhclient -v

這一篇 針對 /etc/modprobe.d/ath9k.conf 的 encryption 設定

希望能夠幫你
補充
1. ath9k 晶片很多 所以 Bug report 也很多 需要碰運氣
https://bugzilla.kernel.org/buglist.cgi ... tent=ath9k
https://bugs.launchpad.net/ubuntu/+bugs ... importance

2. 在測試 無線網卡期間 把 有線網卡 disabled 以免作怪
