I have Galaxy Tab 7.7 tablet running Android 3.2. Recently, I'm having connection problems to my home Wifi router. The device keeps scanning for Wifi access points for long periods. My home Wifi router is shown with a "Not in range" message next to it in the Wifi settings screen. However, sometimes after long period of time, the device randomly connects to the Wifi router.
It is worth mentioning that during the scanning mode the device does not detect any Wifi access point even thought where I live there are many Wifi access points (over 8 access points).
What is the solution to my problem?
