How to configure wifi with my samsung GT-B7722. It connected but whenever i tried to browse internet it showing DNS failed..Plz help me..

Download PC connectivity software from Samsung support GT-B7722.

I'm not sure whether you tried connecting to internet in WIFI enabled Zone. Search for WIFI in WIFI Menu, same like we do for Bluetooth. Some WIFI will ask for Password, If you know the password give it and enjoy. Mine is working fine,

1.Verify the network key you have entered in the WIFI settings.

2. Check the Encryption type is TKIP.

3. Uncheck static IP in advanced settings.

4.Protocol must be set to HTTP in WIFI settings.
