Hi, I just bought a brand new macbook pro, version 10.5.3. Im trying to connect to my home wireless network with a WRT54G router. Right now I have two desktop PCs with wireless plugs running off the router. There is no password for my wireless, but I have added the Macbook onto the "allowed" computers list on my router. When I turn on my Airport, I can see the network and I can connect to it. But once I am connected, I cannot access the internet. In my Network Preferences, it says the Airport has no IP address. Right now, I am plugged into my shaw modem with a cable, because plugging it into the router doesn't work either. When I try to renew DHCP lease, nothing works. My laptop works fine when I plug it straight into the modem, but there seems to be an issue with the router itself. Any ideas?
