I've been fighting with this problem for a couple weeks now. I've made some progress, but haven't gotten to the point of a truly stable internet connection via WIFI.

Unfortunately, the issue is at work, and I do not have access to router configuration. I'm hoping to narrow down the issue to something on my laptop.

Steps I've done so far..

  1. Switched to using Wicd instead of Network Manager
  2. Using static DNS of 8.8.8.8 and 8.8.4.4
  3. Updated adapter drivers

This got me to a point that I could at least connect to the internet, but I'm still dropping every 5-10 minutes, and DHCP has trouble resolving. Usually takes me 3-4 attempts to connect/reconnect.

Here's the results of the wireless script I've found:

Any insight/tips would be greatly appreciated.

You have the same hardware as i do so i hope this works for you. Open a terminal and type the following commands.

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

If you find the wifi isn't as stable as you'd expect, use this command after booting (yes everytime sorry).

sudo modprobe rtl8821ae

Good luck and happy coding!
