Disable WIFI Power Save on Raspbian Jessie

Old way - Not working:

• Use iw wlan0 get power_save to see if the wifi power save feature is enabled or not
• If you want to permantently disable it add this to the /etc/network/interfaces after the iface wlan0 line wireless-power off
• Reboot and if you run iw wlan0 get power_save you should see that is off.

New way:

• It's easier to add ONE line to /etc/rc.local
• /sbin/iwconfig wlan0 power off
• That's it, done.

• dtoverlay=w1-gpio or
• dtoverlay=w1-gpio,gpiopin=x
