I've had my Captivate for about 5 months and most of that time has been relatively trouble free. Lately, though, way within the past few weeks, I haven't been able to connect to my home wifi network. I know the network is working, as my PS3 uses the wifi connection and it's working fine, and the phone does see it when it scans for wifi signals. I haven't changed anything with the wireless router, either. When I go the wifi settings screen of the phone, it lists my home network along with others in the area, and apparently tries to connect for a while, reading "Obtaining IP address from..." underneath the network name for a minute or two, before reverting to "Remembered, secured with WEP" and then sometimes "Disabled, secured with WEP". Any ideas on what might be the problem and what I might do to fix it?
