我已经为这个问题奋斗了几个星期了。我取得了一些进展，但还没有达到通过 WIFI 真正稳定连接互联网的程度。
不幸的是，问题出在工作上，我无法访问路由器配置。我希望将问题缩小到笔记本电脑上。
我迄今为止已完成的步骤......
- 切换到使用 Wicd 而不是网络管理器
- 使用静态 DNS 8.8.8.8 和 8.8.4.4
- 更新的适配器驱动程序
这让我至少可以连接到互联网，但我仍然每 5-10 分钟掉线一次，DHCP 解析有困难。通常我需要 3-4 次尝试才能连接/重新连接。
以下是我找到的无线脚本的结果：

如能得到任何见解/建议我将非常感激。
答案1
您的硬件与我相同，因此希望这对您有用。打开终端并输入以下命令。
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
如果您发现 wifi 不如您预期的那样稳定，请在启动后使用此命令（是的，每次都是这样，抱歉）。
sudo modprobe rtl8821ae
祝你好运，编码愉快！
