Server Loss

[popcorndog]

I am experiencing very weird behavior with my home network. My network consists of:
DSL modem
connected to
Linksys router running DD-WRT
connected to
D-Link 8 port Gigabit Switch
connected to
Windows Home Server
Computer
Canon Printer
2 HD 200s
Wii
D-Link 5 port Gigabit Switch
connected to
PS3
HD 200
Computer

Now for the weird behavior. I can go for weeks using any HD 200 without experiencing any issue connecting to the Sage server. If I connect to the internet using my PS3 and then try to use any of my HD 200s, the HD 200s do not see the server. I can use any computer and see the server and the internet after this happens. If I look at the D-Link 8 port switch, all the port lights will be blinking.

To reset the system, I have to first unplug the D-Link 5 port switch and then unplug the D-Link 8 port switch. After a few seconds, I can plug them back in reversing the order. I can then turn any HD 200 on and it will connect to the Sage server. To add another interesting tidbit, I changed routers for a short period of time to a NetGear router. While using the NetGear router, I experienced no issues. The NetGear router recently died and I brought out the old trusty Linksys router running DD WRT - wahla - the problem returned.

Any network guru have an idea what might be happening to cause this issue?
