Connecting a cable modem to wirless router

Specs: Windows XP
I am trying to connect a Netgear wirless router to my cable modem. I have followed the instructions on the set up wizard but it fails to get a connection with the IP and DNS info I provide.
I got the IP address info by connecting intially direct from the modem to the PC and then went to Run CMD and type ipconfig /all. I then started the set up wizard and followed the instructions, turning things on in specific order etc. After input the IP and DNS info it reports an error and tells me to check the address information is correct. My internet is a static IP connection (so it tells me and the IP information doesn't change).

Can anyone offer any advice?

The router will pull the WAN IP from the modem. Probably, leaving the DNS blank will turn on automatic DNS.

Thanks for the reply. I tried that but it comes up with "invalid DNS address" so wants me to add something there.

The router's wizard should have a setting for dynamic/static DNS, and if not, leaving DNS blank "should" default to dynamic. If you don't see anything like that in the wizard, go directly into the router from your browser, by entering its LAN IP, which might be (see the user manual, or find Default Gateway in ipconfig). You'll have much more detailed settings there. If you have to put in a DNS address, you can get one from your ISP, or you can use OpenDNS (, or other offerings such as Google's.
