Realtek RTL8188CE无线驱动程序在Ubuntu 14.04中不稳定

由于全新安装了Ubuntu 14.04，几分钟后我失去了互联网连接。重新启动或从待机状态唤醒后，我会回来。Realtek RTL8188CE无线驱动程序似乎是一个已知问题。同样适用于Ubuntu 12.04。

详细信息如下：

嗯，不能肯定地说，freedomben司机实际上为我工作。

因此，如果您不确定如何做，请执行以下操作（为简单起见，我将避免使用git）；

转到：https : //github.com/FreedomBen/rtl8188ce-linux-driver/tree/ubuntu-14.04

...并下载zip文件（右侧）

...下载后，将.zip文件解压缩并'cd'到其中。

最后运行install.sh（$ sudo ./install.sh）。

说明也可以在git上找到...

希望能帮助到你

我有相同的卡，并且遇到相同的问题。尝试升级到3.13.0-32通用内核，在路由器上关闭“ n”频段，并使用通道1。

我的14.04 LTS上已经有较新的内核，只需在启动过程中按住“ shift”键启动到Grub，然后选择3.13.0-32通用内核即可。如果有任何问题，重新引导将选择您的旧内核。即便工作正常，也可以将较新的内核设置为默认内核，以免重启。

现在，在终端中使用以下命令更新驱动程序：

echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce

*感谢Wildman帮助我解决此问题。

打开终端并依次运行以下命令：

sudo apt-get install linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
modprobe rtl8821ae # once booted ...just in case
