Samsung Galaxy SII wi-fi stops working after a few minutes

[boulderado]

After I first connect to my home wi-fi it works great for a few minutes and then it stops working. If I restart the phone it works fine again for a few minutes. The phone stays connected to the wi-fi, but simply stops working. We have three other Android devices that work great with the same wi-fi (can go for hours without any problems). Talked to ATT and they suggested a factory reset, did that and same issue.

We are stumped, any ideas??
