trouble w/ Adelphia cable & wireless

[Sybren]

I'm using Adelphia cable and a D-link 524 wireless router. Using an Apple Powerbook plugged directly from the cable modem into the ethernet port of the Powerbook, I am correctly assigned an IP address and I get internet access just fine. Using a Dell laptop or the D-link wireless router (plugged from the WAN port of the router into the cable modem, which I am almost positive is correct), no IP address is assigned by the cable modem, and I get no internet access. If I try to "renew IP address" (on either the router or the dell computer), it times out and I still get no IP address.

Any suggestions as to how to fix this problem? I'm more concerned with fixing it for the wireless router, because if I can get it to transmit the internet, then the dell laptop can get internet that way. It almost seems as if the cable modem will only give an ip address to my Powerbook ethernet card's physical address... is this possible? any fixes?

thanks in advance!

power cycle the modem. Cable modems are bound by client mac. You could try cloning the mac of your powerbook to your router. Then pull the plug on the modem and let it reboot.
