If you have been following recent threads, you might already have examined your Ethernet LAN adapter, DHCP (check ipconfig) and network protocols. Worth checking if you haven't. Try it through any other desktop or laptop as well.
Most routers are reasonably straightforward, presumably this one included once you get to access it, but I think that it's a bit rich of Netgear to claim anything special for this model. It's probably quite conventional.
