I turned on gps and inserted the location trigger but it says that its required to turn on wifi.
Same here. GPS is on. Still won't trigger wifi to turn on based on location. Because wifi has to be on for location settings to work? Makes no sense at all.
Hmm yea I couldn't get it to work either with gps. I did get a wifi trigger to work nicly... I for one would rather leave wifi on all the time then gps. Make sure your enabling the google location thing also in the settings menu.
