Recovery disk can't communicate on network

I can't get my recovery CD to communicate with devices on my network.  I tried DHCP first, which clearly timed out and didn't give me an address on my network.  I also tried statically assigning the address of my computer.  Doing that, I can ping my own IP address, but I cannot ping the default gateway or any other computer on the network.  I get "destination not reachable" rather than timeouts.  It has the right network driver:

Realtek 8168 NT Driver

{4d36e972-e325-11ce-bfc1-08002be10318}

64-bit

8.7.1025.2012

Windows Client: 2000, XP, Vista, 7, 8, 8.1

Any ideas?
