Improve WiFi stability

[RTheren]

Hello there,

To make WiFi usable on PP (way more stable than normal), run the following commands in terminal:

Code:

$ devel-su
# echo 0 > /sys/module/8723cs/parameters/rtw_power_mgnt

Then turn WiFi off and on again. Ping to any IP/hostname doesn't drop so often now, and most apps work much better.
