I have an Eris with Android v. 2.1 and a Belkin 54g router. The phone lists my home network in its list of of wifi networks. When I press the entry, an info box says that signal strength is good and security is open. (for the purpose of trying to have my phone connect). When I press "connect," it says "Obtaining IP address..." Then after a couple of minutes, it says "Unsuccessful." My phone has connected to other wi-fi networks with no problem; indeed, it has done so automatically, with no effort on my part. My router assigns IP addresses via DHCP. It also broadcasts its SSID, which the phone recognizes. Has anyone here encountered this problem and solved it? How?
