联想 IdeaPad Yoga 13 无线

联想 IdeaPad Yoga 13 无线

我在联想 IdeaPad Yoga 13 上运行 Ubuntu 16.04,但电脑无法连接到 wifi。连接菜单中没有显示无线网络。我尝试安装此驱动程序基于这个答案,但什么都没改变。我将 r8723au 模块列入黑名单以/etc/modprobe.d/blacklist.conf禁用之前安装的驱动程序,但无线仍然不起作用。

lspci | grep Wireless并且lspci -nnk | grep 0280 -A2两者都没有输出,但是的输出lsusb包含无线网卡:

答案1

你有两个都本机驱动程序 rtl8xxxu 和已加载的编译驱动程序 8712au。我怀疑它们存在冲突。除非我们发现其他问题,否则我怀疑本机驱动程序会工作得更好。让我们将 8723au 列入黑名单:

sudo -i
echo "blacklist 8723au"  >>  /etc/modprobe.d/blacklist.conf
exit

重启。

接口是否扫描并查看网络?

sudo iwlist scan 

如果它看到网络,它可能会连接。

既然我们知道这是无效的,我们将反转顺序并仅尝试编译的驱动程序。

gksudo gedit /etc/modprobe.d/blacklist.conf

如果您没有文本编辑器 gedit,请使用 nano 或 kate 或 leafpad。更改最后一行,现在内容为:

blacklist 8723au

读书:

blacklist rtl8xxxu

仔细校对,保存并关闭文本编辑器。重新启动。

现在可以扫描吗?

从您的粘贴中,我们发现存在固件问题。让我们尝试更高版本的固件,看看是否有帮助。使用临时可用的互联网连接:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb
sudo dpkg -i linux-firmware*.deb
sudo modprobe -r r8723au && sudo modprobe r8723au

此外,您的无线网卡处于监控模式;它应该是受管理的:

sudo ifconfig wlx2016d8b033d7 down
sudo iwconfig wlx2016d8b033d7 mode managed
sudo ifconfig wlx2016d8b033d7 up

另外,请确保在网络管理器中,在 WiFi 下,模式是客户端而不是 AdHoc。

有改善吗?

答案2

我没有从命令中获得任何输出lspci -nnk | grep 0280 -A2,但我从 获得了输出sudo lspci -nnv |grep ualcom,其中 ualcom 是我的卡名称的一部分。您需要将其替换为您的卡的名称。

我有一台联想 i310,运行 Ubuntu 16.04(内核 4.4)。硬件有 Wi-Fi,我在 Windows 上使用它。Wi-Fi 硬件已打开。但是,当我刚启动笔记本电脑时,Wi-Fi 不起作用。

我的解决方法是:

  • 打开笔记本电脑

  • 按住电源按钮几秒钟

  • 再次打开笔记本电脑

现在,Wi-Fi 神奇地起作用了。

缺点是每次打开笔记本电脑时都需要执行此操作。仍在寻找永久解决方案。
