I assume you are trying to set your netgear up wirelessly? If so, you need to connect it via ethernet cable first and then set your router up that way.
If your router is already set up, have you set any security on the router for wireless access? (WEP etc) If so, you need to key in this information for your macbook pro to access your network.
If your SSID is set to "hidden" on your router, you also need to key in the SSID of the netgear in the new macbook pro, otherwise it will not know which network it should be joining (especially if there are other wireless networks in your area.)
