Fixing wifi dropouts on Raspbian / Raspberry Pi

From this article, if you’re using one of the Wifi dongles on a Pi 1 or 2 (Pi3 has built in wifi), you can prevent the random dropouts during periods of inactivity by:

sudo nano /etc/modprobe.d/8192cu.conf

and then paste in and save this:

options 8192cu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1

and then reboot.
