First, I feel your pain. This isn't easy. Here's some facts...

In what many call the BEST setup, modem in "bridge" and the router logging into DSL (WAN set PPPoE) getting to the modem page is not easy at all. In fact, I'd hate to suggest it to anyone but the experienced. The reason is: The router is tunneling PPPoE right through the bridged modem with no easy way to talk to it. People prefer this because all their routing is handled in one place - the router (and the modem's routing doesn't interfere).

That is the basic problem... you have two things wanting to be routers - a modem with built-in router functions and a separate router.

That said, here's what many do...

The router and modem must be on separate network "subnets". Was that correct that you changed the router to 192.168.1.2? That is not a separate subnet - it's a separate address in the same 192.168.1.x subnet. If you meant 192.168.2.1 then that is a different subnet.

Modem all set to login to your DSL ISP like Verizon probably suggests.
Set the modem and router to separate subnets (router on 192.168.2.1 is fine).
Linksys WAN to 2100 Modem.
Set Linksys WAN to obtain address automatically.
All your PCs hook to the router LAN.

You should now be able to get to the modem AND internet. Power cycle everything to be sure.

Hope this helps. How close are you already to this configuration?

If it undoes a lot of what you were told, just holler and fill us in.

EDIT: I'm very familiar with the Westell 2100. Turns out, in default configuration, it automatically is in bridge mode and router mode at the same time. Westell calls it a "PPPoE shim" or something like that. It's somewhat unique in the DSL modem world.
