Hi, We just bought a new iMac to replace my girlfriend's 3 year old, fried iBook and are having problems connecting to the internet via our wireless router. I entered the WEP password and it appears that the Airport recognizes our router - the cone shaped airport icon shows a full 4 lines - but when I launch Safari, it says I am not connected to the internet. I clicked on "network diagnostics", then "airport" as the network port configuration, then selected our wireless network. It then asks if we use PPPoE or DHCP. I'm not sure which we use but neither is working for me. On the left side of the Network Diagnostic screen, it shows the Network Status. Airport is green, Airport Settings is green, Network Settings is yellow, ISP is red ("failed"), Internet is red, and Server is red. My Powerbook is working with our wireless network just fine, so I don't think it's that. Any suggestions? Thanks.
