Netgear Router problems

I just got a new laptop and Netgear router (WNR2000). I already had a home network with an old microsoft router and cable modem. I can use my laptop in the old network just fine (both wired and wirelessly), but when I use the new Netgear router, I cannot get on the internet (neither wired nor wirelessly). I can only get local access to the router/network. This is the only computer in this network and I have the settings to find the IP address and DNS servers automatically. Has anyone seen this problem and have any suggestions for things I should consider to fix this? Thanks.
