dhcp connection lost at switch?

Hello. I am upgrading my home office network to gigibyte speeds, which includes replacing my old FVS318 Firewall/Router with a new FVS318G v2 Firewall/Router, gigabyte switches and Cat6 ethernet cables.

The only problem I am encountering is that most of the devices connected to a NetGear G5608 v3 switch at my entertainment center lose DHCP connection to the firewall/router, and therefore cannot connect to the Internet. This includes a NetGear WAC120 wireless access point and a Sony BluRay player. These devices work properly when connected directly to ports on the new Firewall/Router. Oddly, a Sony PlayStation3 connected to the switch *does* connect properly to the Internet.

I don't think this is an issue with the switch, since other switches I have tried in that position have the same issue (except that the Sony PlayStation 3 does *not* connect to the Internet with those switches.

So I suspect I am missing something in the setup of the FVS318G v2 Firewall/Router. I would appreciate any suggestions on how to resolve this.

Thank you!
