The wifi signal from my router to my Samsung Galaxy Tab goes back and forth between "not in range" to "secured". The wifi will last for about 10 seconds and then loose the signal. I don't think it is the router because I have 5 other devices hooked up to the router and they work just fine.

There can be a variety of reasons why the wifi no longer works. Did you make sure that the wifi is on in the settings menu?

Go to settings -> wireless and network -> mobile AP -> press the mobile AP check mark -> click yes. the access point name and password is located on the bottom of the page in the mobile AP menu. cheers.

You have to re enter your security code on your tab

Hi astone5638,

The first thing to try to correct this issue is to remove the battery and SIM (if you have on, varies by carrier) from the phone and wait 20 seconds, then, with the battery still out, plug it into your wall charger, then place the battery and SIM back in and turn the phone back on.

Hope it helps.

Thank you for using FixYa.
