I think my router is D-E-A-D, dead!

I have a Dell 2350 Broadband Router, Model # WRTA-108GD, a Westell DSL Router with Bellsouth DSL service. The 2350 was hooked up to a Dimension E310 via an ethernet cable in the LAN 1 postion and I used the wireless hookup on my INSPIRON 6000. I came back from vacation and was unable to display any internet pages with either firefox or IE. I tried repairing the connection, resetting the modem, the router, and my computer all to no avail. I keep getting "server not found" messages when I try to hook up through the 2350 either wirelessly or by connecting to the LAN outlets. When I hook up directly to the DSL modem I can connect just fine. What's next?
