Will not connect to wifi actually exchanged it once already at best buy and still the same problem. Just says authentication problem any ideas as to what's wrong and has anyone else had this issue?
Is it every Wi-Fi point you try to connect too or just the one at your house? You can also try temporarily turning of the encryption on your home router and see if you can connect then.
As Bitterman already asked, have you tried it on other wifi networks? Is the problem on every network, or only your home network? If you've only had problems at home, and exchanged the phone and have the same problem, it sounds like a network problem, not a phone problem. Have you restarted the router?
