I have limited knowledge of android....but I can't figure out how to "properly" set it up for AT&T. Works fine with Comcast though. Files in root directory for xfinity but none for AT&T.....?
Just need to go into setting menu and select your method (Ethernet or wifi)
If ethernet you simply connect.
If wifi you enter your password and click Connect.
Will work with ANY internet provider ! No special files needed.
