排除 Wlan 故障,必备的 WLAN 调试信息?

排除 Wlan 故障,必备的 WLAN 调试信息?

我的 Wlan 无法连接,只显示网络,但互联网连接只能通过 RJ45 连接。我希望得到某种总结性的答案,以通用的方式解决此类问题。我在下面列出了一些可能有助于解决问题的命令。是的,我尝试解决当前的问题,但我还想知道将来调试此类问题的基本命令。

% ls
debugWlan.sh  specs 
% cat debugWlan.sh > specs 
% ./debugWlan.sh >> specs
PCI (sysfs)  
% cat specs

cat /etc/lsb-release 
sudo rfkill list all
sudo lshw -class network

答案1

您要连接哪个无线网络?您使用网络管理器吗?您运行的是哪个 Ubuntu 版本?

运行网络管理器(在 11.10 上,它是我顶行中的一个图标,旁边还有电池、蓝牙、扬声器、日期等)。右键单击图标,并确保两个都已选中“ Enable Networking”和“ ”。Enable Wireless
