Ubuntu – Realtek RTL8188CE wireless driver unstable in Ubuntu 14.04

driversrealtekwireless

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:

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
