最近我将我的操作系统从 12.10 升级到了 13.04,运行良好。
我今天才遇到这个问题,但从早上起我就无法连接到某个 WiFi。我这里有两个 WiFi,我可以连接到另一个。
至于 WiFi,没有问题,因为其他使用 Windows 的人可以正常连接。我不知道如何解决这个问题?
注意 - 我已重新启动 WiFi 和系统两次以解决这个问题。

答案1
看起来这个硬件的 Wi-Fi N 配置出了问题。
请尝试:
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1
现在尝试重新连接,如果有帮助,请按照以下步骤操作
查看
/etc/modprobe.d
是否存在类似的文件intel-5100-iwlwifi-disable11n.conf
,然后编辑该文件sudo gedit /etc/modprobe.d/<filename_here>
编辑以下行:
options iwlwifi 11n_disable=1
到
options iwlwifi 11n_disable=0
保存并重新启动。
如果不存在文件,则创建新文件
gksudo gedit /etc/modprobe.d/iwlwifi.conf
添加新行:
options iwlwifi 11n_disable=1
保存并重新启动。
