在我的华硕笔记本电脑上，我连接到互联网，几乎每 10 分钟，我就会断网，但仍然连接到 WiFi。有关该问题的任何附加信息都将提供！

答案1
安全答案
等到新的驱动程序最终合并到 Ubuntu 内核模块中。 考虑将您的 Ubuntu 安装升级到 15.10（或本月晚些时候升级到 16.04）。
替代答案
如今，WiFi 卡价格低廉，而且相当标准。您可以随时打开笔记本电脑，弹出预装的 PCIe WiFi 卡，然后安装与 Ubuntu 兼容的卡。（别忘了重新安装两个天线！）
不安全的答案
有人说这里新版本的 Realtek 驱动程序解决了这些问题。
**请注意，使用非生产的驱动程序可能会损坏您的硬件。**
**风险自负！**
**你被警告了！！！**
以下是获取较新驱动程序的方法：
首先，确保已安装 build-essential 包（用于 gcc、make 等）、git（用于获取外部源）和 linux 标头：
sudo apt-get install build-essential git linux-headers-`uname -r`-generic
然后创建一个目录并克隆并构建当前的 rtlwifi 驱动程序：
mkdir -p Applications/lwfinger
cd Applications/lwfinger
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new/
make
sudo make install
sudo depmod -a
然后安装驱动程序：
sudo mv /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8821ae/rtl8821ae.ko /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8821ae/rtl8821ae.ko.save
sudo mv /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8192ee/r8192ee.ko /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8192ee/r8192ee.ko.save
sudo modprobe -v rtl8821ae
要撤消这些更改：
sudo mv /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8821ae/rtl8821ae.ko.save /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8821ae/rtl8821ae.ko
sudo mv /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8192ee/r8192ee.ko.save /lib/modules/`uname -r`-generic/kernel/drivers/staging/rtl8192ee/r8192ee.ko
