Raspberry Pi losing Wifi connection

I have a Raspberry Pi connected to my printer to enable wireless printing. However my Pi was losing its Wifi connection. I read on the internet that I should turn off Power Management by creating a file:

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

The following code should be added.

# Disable power management
options
8192cu rtw_power_mgnt=0 rtw_enusbss=0 rtw_ips_mode=1

With the following command you can check whether power management is disabled:

 
sudo iwconfig wlan0

Will test it for a while and update you with the results..
