My wifi worked perfectly for the first two weeks of ownership but now the phone has trouble getting onto my wireless network at home. It will hop on and off of the network intermittently but it is not receiving it's IP configuration. DHCP is enabled. My 3G is on the wireless network without any problems and my laptop too. But, yesterday my iPhone 4 got onto the wireless network at work without any problems. I've tried renewing IP config to no avail. I'll reconfirm DHCP configuration on the work wifi connection on Wednesday but in the meantime, I'm looking for other things I could troubleshoot. Any ideas? Thanks. *Edit* In a mild fit of rage, I tried another lease renewal and now I seem to have full configuration from the DHCP server. We'll see how long this lasts.
