Hello, I'm having a problem where the wifi disconnects randomly and I mostly see this when I'm connected to my MacBook with the USB cable. But still happens sometimes without. The signal strength is full, and degrades after a while even when in the same room as the router. I tried resetting the router and renewing lease. Don't know what else to do other then restore. I'm running iPhone OS 3.1.1. Thanks for tips/help, Mr. Gecko.
