I buy 2 Incredible 2's last year and they have worked great. I had no problem connecting them to the house wifi. Well, mine I had to return recently due to an issue with the power button. The new Like-New Incredible I received works fine except I can not get it to connect to wifi. I was originally using WEP and after doing some reading thought that that my be the problem so I changed it to WPA without any luck. I even open the network and still no luck. The phone sees the networks fine, just will not connect to them, any suggestions??
My wife and I both have Incredible 2's and we have never had this problem. Especially since the previous phone was working on the same network, it may be a problem with that particular phone, but you might try Verizon support to see if they can get it working for you.
