New Info.
Wasn't aware of that capability with Belkin. I'm more of a LinkSys/Cisco type. Anyhow, there's probably a setting on it to switch among the various modes. The configuration settings should be verified. My main point was that it could well be that the double layer of NAT (particularly if everything was withing the same /24) was likely causing the collisions, timeouts, access issues, etc. There is rarely a need to have two layers of NAT on a network with 3 or so PCs.
