无法连接到无线 13.10

无法连接到无线 13.10

我在使用 ath9k 时遇到无线连接问题,无法连接到任何无线网络。我可以在 Windows 8.1 上顺利连接到无线网络,但在使用 ubuntu gnome 时却没有成功。

任何帮助都值得感激。

操作系统:Ubuntu Gnome 13.10

到目前为止已尝试过的:

sudo modprobe -r ath9k

sudo modprobe ath9k nohwcrypt=1

sudo modprobe -r brcmsmac

echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf

无线网卡:TP Link TL-WDN3800

答案1

执行:

sudo modprobe -r brcmsmac

然后尝试连接。这样应该可以了。

如果有效(或者无效)则执行以下操作:

echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf

然后重新启动。

答案2

尝试使用

rfkill list all

在终端中。它将显示类似以下内容的内容

`0:phy0:无线局域网软阻止:是硬阻止:否 1:hp-wifi:无线局域网软阻止:否硬阻止:否

如果他们中的任何一个回答是,请使用rfkill unblock all 希望这能解决问题
