Have you tried deleting the entry on the phone and reestablishing it. Just a thought.

Yes, even went as far as deleting all of my saved connections. Most were from hotels, work, etc. I did so twice, once rebooting before adding it back. On my wife's phone, here Wifi works great - its the phone button that is messed up, so bad that Verizon is sending her another phone.
