华硕X200M，与Realtek RTL8188EE的超慢WiFi连接

Question

我刚买了一台新的华硕X200M笔记本电脑，带有Ubuntu的双引导Windows 8。问题是，当我登录Ubuntu时，我遇到了一些无线互联网问题。当我访问http://www.speedtest.net/时，结果如下: Pint: 15 in下载速度: 0.8-2.5Mbps (我已经尝试过几次)上传速度:3-6 6Mbps，我也不能访问任何公共WiFi，无论是在网络设置中输入密码，还是在浏览器中输入密码。相反，当我使用Win8时，我的下载速度和上传速度都会达到40-50 50Mbps。注意，我没有尝试使用Wins8 access公共WiFi。

下面是关于我的X200M的一些信息：

我尝试过许多不同的方法。它们都不管用。
