DM200 Stopped Working with Router

[x225]

I've had my DM200 modem connected to a router for about a year with no problems. Now, without changing anything, if I connect ethernet from the modem to my computer, it's fine. But if I connect ethernet from the modem to the router, and ethernet from the router to my computer, it doesn't work. WiFi from the router doesn't work, either.

I don't think it's a problem with the router, because I've tried three separate routers, and it doesn't work on any of them.

Th the LEDs on whatever the router is offer any clues?

Is the DM200 in modem only mode? It should be. Or put the router into wireless access point mode.

Did you restart the whole network as specified?

Be sure to restart your network in this sequence:

• Turn off and unplug the modem.
• Turn off the modem router and computers.
• Plug in the modem and turn it on. Wait 2 minutes.
• Turn on the modem router and wait 2 minutes.
• Turn on the computers.
