Can NO longer connect thru router thru modem

Question

Hi Guys (and other Gals),
I am running 2 Windows XP Pro SP2 PCs that were wired to a Linksys WRT54G v.6 Broadband Router (with both 4 Wired ports and wireless capability) to a Verizon furnished Westell C90-610015-06 Rev. E, DSL modem. All was working peaches, both PCs worked great thru their wired connections to the router - then to the modem.
Wham Bam and the setup no longer works!! I seriously believe that Verizon has changed something(s) that they are not admitting to, in the last 2 or so months. I can plug directly from modem to either PC to and it works, but as soon as I interject the router - nothing, no connection, zilch!
Spoke with Verizon people who had me go thru some steps to "Bridge" the modem, (they didn't know what to do to the router or just wudn't admit to it), but nevertheless it wouldn't work! This was very late one weekend night. Came back to computer the next morning and plugged in directly from modem to PC and "that" wouldn't work, so had to spend 45 mins on phone with verizon again explaining everything again till they walked me thru resetting up the modem but would not do a thing for the router.
Called Linksys - no help, router was out of warranty, told me to download their documentation for help. I have now over 25 linksys docs telling me how to set up a router for connection, etc. 3 different ones just for setting up router for DSL connection. None of them work thru the router then thru the modem!  I had someone tell me to set up the router with a static IP account, that required some info from verizon that I cud NOT get from them. I guess they don't train the Indians on all that they need to know?
Okay, I have been rambling on but I am so very P.O.'d it is ridiculous, as for all the time I have wasted on this verizon debacle!
As it stands now, I am connected directly from modem to one PC, 2nd PC and router are just sitting here gathering dust.
can anyone PLEASE give me some much desired and appreciated help to get this network working again, Please?
Please go slow and bear with me as I am a "newbie" when it comes to this networking lingo and such!
Thank you so very much!
sincerely,
Sue

I figured out the answer to the question. The Verizon tech had me reset the wireless router, thus all setting were moved back to the default stage. He then could not figure out why the laptop still would not connect and said to call HP, and if that did not solve the answer (HP said nothing wrong with laptop,as I said), I could call tech service and pay a fee. Luckily, after searching and searching, I found that if you reset your wireless router, you have to enter the new settings on all devices connected to the network. I write down all the info from the desktop and entered it onto the laptop. Connected immediately. Here's my one complaint about calling tech support, the tech should have told me to reset all devices. Someone not willing to take the time or accept the answer that a three month old laptop was too old, would not have taken the time to search for an adequate answer to fix the solution, therefore, the easiest way would be to pay the tech support fee. If you contact tech support and the answer they give you does not sound right, search on your own. While their are good tech support agents at Verizon, this one should have given me an adequate response to reset.
