Need the interface for netgear wgr614

Since it's built in, you could just simply connect to the network. By default you get something in the 192.168.1.x where x is greater than 1.
If you do, open up internet explorer and point type in 192.168.1.1. on the address line. It will open up the Netgear router. Default login is admin and password. Then you can set up the router.

If you don't get 192.168.1.x for an IP address (using ipconfig), then go to the wired network card, and give yourself an address of 192.168.1.5, 255.255.255.0, and 192.168.1.1. Use 4.2.2.2 for DNS. That should let you log into the router.
