Hi guys! I just upgraded my 8GB iPhone 3G to 2.2.1 yesterday and have had Wi-Fi issues ever since. I can connect to the network and a check mark comes on next to the network, but in the top it still shows as connected to At&t 3G, not WiFi. All my apps that only work on WiFi don't work either. The odd thing is that now my 1st Gen MBP has the same issue. Thanks in advance for any suggestions! EDIT: Right after I posted this I restarted everything (modem, router, all computers, iphone) and now it finally seems to work. Is it possible to delete this thread?
