It all started normally, the phone connected to the wifi just fine. Then as time passed, just a few weeks, the phone started to have big trouble connect to the wifi although the signal is excellent, it gets unconnected back and forth and the connection is very slow compare to other phones. Any know how to fix it?
I did not find the right solution from the internet.
