Curious and rather major glitch that has cropped up on my iPhone 3G in the past week or so that I'm hoping someone may have a few pointers for: It won't maintain a connection to my wifi network. If I go into the wifi settings, my network shows up on the list of available networks and you can see the status switching every few seconds between connected and not connected. Never stays connected for long enough for the wifi connection to be useful. Have tried: - rebooting the router (it's a Netgear N box - a year or so old, have had no problems connecting the iPhone to it up to now & no problems with other devices using it) - rebooting the iPhone - forgetting the network in iPhone settings and reconnecting ...with no joy. I'm stuck at home with a broken leg at the moment and can't get out to check it with another network, unfortunately. Only get a GPRS data connection at home, which rather limits the phone's usefulness! Anyone else come across a similar problem?
