Network suggestions?

[chrishallowell]

Just trying to figure out what I need as far as networking hardwire for a new HDHR and 3 new HD200.

Here's what I have now:
High-Speed DOCSIS 2.0 Cable Modem(DCM-202)
AirPlus Xtreme G Wireless Network Router 4-port (DWL-926)
PC (Q6600, 1.5TB, 2GB RAM, dual gig LAN)
USB tuners (2 Cable analog)
1 HVR-1600 (1 digital and 1 unencrypted QAM)
1 standalone Bluray player

Here's what I have on order:
3 HD200

Here's what I'm thinking about getting:
HDHR

How do I add another router/switch? (I will need 6-ports: 3 HD200, HDHR, PC, Bluray) Or should I replace the one I have?

Can I use the 1st dual gig LAN on my PC for the HDHR? and then the 2nd dual gig LAN for the router?

What's the difference between a router and a switch?

Thanks!

Just get yourself a 8 port gigabit switch and plug that into your router. Everything you want to use for your SageTV system can just plug into the switch. All of that traffic will just stay on the switch. The only time it will use the router is when a PC goes out to the Internet.

Thanks Gerry!

Update: I got an 8 port gigabit switch and connected to the wireless router. Everything works perfectly! Thanks again for your help
