i have a asus TF300t transformer pad for 1 year, all has been good up to now, we were experiencing internet problems at home, but has since been fixed, rooter working well, wifi great , every device in house working apart fro my tablet, it has full wifi support but will not connect me to the internet , i tried the cold shutdown but that did not work, it keeps saying authentication error, does anyone else have this issue, or do i have a malfunction and take it to get fixed.
