I'm having an issue with the wifi near state. I've got a profile that's supposed to trigger if I'm on AC power and wifi near is a particular wifi network. This has been working beautifully for me all week until today when it went off when I was 15 miles away from where the wifi is. Why is wifi near not detecting that I'm not near that wifi network any more? I leave wifi turned on 24/7 on the phone just for this purpose.
It can take up to two scan cycles for Tasker to accept that the Wifi is no longer near. This prevents the profile from bouncing between active and inactive when you are near the edge of the coverage area. If your device is asleep and using the default settings, this could take up to 20 minutes.
This is the only non-bug reason I can think of to explain what happened.
Also, if you check the "Toggle Wifi" option in the context, you can turn Wifi off and Wifi Near will still work.
