Asus X200M, Super Slow WiFi Connection with Realtek RTL8188EE
I just got this new Asus X200M laptop, dual-boot Windows 8 with Ubuntu. The problem is that I am having some wireless- internet issues when I log-on with Ubuntu. When I go to, , the results are following: Pint: 15ms Download Speed: 0.8-2.5Mbps (I have tries for a few times) Upload Speed: 3-6Mbps Also, I can't access to any public WiFi, both the one you enter password in network setting and in a browser. In contrast, when I use Win8, I get 40-50Mbps for both Download speed and Upload speed. Note, I haven't tried to use Wins8 access public WiFi.
Here are some information about my X200M:

If you did not upgrade to 14.10 yet, you can try another driver
sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware
