Realtek RTL8188CE wireless driver unstable in Ubuntu 14.04
Since a fresh install of Ubuntu 14.04 I'm loosing internet connection after a few minutes. I comes back after reboot or wakeup from standby. That seems to be a known issue with the Realtek RTL8188CE wireless driver. The same worked perfect with Ubuntu 12.04.
Here are the details:

Solution 1:
Hm, cant say for sure, the freedomben driver actually worked for me...
so, if you're not sure how to, do the following (I'll avoid git, for simplicity);
goto: https://github.com/FreedomBen/rtl8188ce-linux-driver/tree/ubuntu-14.04
... and download the zip file (right-hand side)
... when downloaded, extract the .zip file and 'cd' into it.
finally run install.sh ($ sudo ./install.sh).
Instructions can also be found on git...
Hope it helps
Solution 2:
I have the same card and was having the same issues. Try upgrading to the 3.13.0-32-generic kernel, turn the "n" band off on your router, and use channel 1.
The newer kernel was already there on my 14.04 LTS, just boot into Grub by holding the "shift" key during boot and then select the 3.13.0-32-generic kernel. Rebooting will select your old kernel if you have any issues. Just if it works, set the newer kernel to the default kernel to survive a reboot.
Now update the driver using the following commands in the terminal:
echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce
*kudos to Wildman for helping me fix my issues on this.
