Thanks so much for your response. Tried several times your suggestion (1) but not work. Tab can detect router wifi but each time I tried to connect, the status changed to "out of range". Changed router security from wpa to wep but still not work. Before the upgrade, it connects every time i turned on the Tab. Do not want the reset to factory setting at this point.Hi Ray...Greeting to you
Try as follow:
1. Forget/delete all wifi setting.
- Power off your router about 2 to 3 min.
- Restart your router.
- Reboot your Tab.
- Try reconnect.
or
2. Factory data reset your Tab.
Keep us inform how it go.
