Hi there
I have a strange, not problematic though, problem. Time to time, my android phone Galaxy S3 would not connect to the wireless. When I look at the phone it states that "authentication error occurred". All I need to do is tap again on the wireless connection of my phone and reconnect it to my wireless. This happens randomly, so it is not really a problem, but just wanted to find out what could it be. This also mostly happens when passing from 3G connection to the wireless connection.

My guess is it could be a time-out of password exchange. Maybe the phone is a little busy at some moments and it takes a while to exchange the password with the router. Right now I don't see any log info on my router.

Is there any way to increase the time of password exchange?

The catch is that I can not repeat the problem, it just happens very rarely and randomly.

Hello!
I have that problem.
