I think you're misunderstanding me. The DGL-3420 is a wireless adapter, not a router. I'm not going to run 70 feet of ethernet cable upstairs. The connection I want goes like this:
Ethernet cable from 360 and PS3 connected to the switch. Switch connected to the wireless adapter. Wireless adapter interfaces with router upstairs. I want two consoles to connect through the single adapter.
