If you need to buy a router, do not buy from Linksys. I bought the WRT54GC more than a year ago and it was working fine until yesterday when I tried to upgrade the firmware. Now it doesn't exist as a router any longer. Its routing and wifi abilities are gone; it's just a hub. Useless. How can an update cause such havoc? I have to buy another one now, unless there is someone who knows how to fix this type of thing. I am open to suggestions. I can't take it back. I don't have a proof of purchase anymore, and it's been at least a year anyway.
This would happen the day I get my laptop.
Ha, I have a friend, actually more like an acquaintance, with a problem with Linksys as well.
I have been using a Netgear router for a year. http://www.netgear.com/products/details/WGR614.php
I use it only for the network and connecting to the internet. There are other features I don't know about, but it's been working fine for a year now.
Did you have any problems requiring the firmware update? Firmware updates are either the commonest of common things to do, or a bane from hell. All in all, for any device, you should think twice before doing a firmware update, everything can go wrong and no matter the brand, you can simply be unlucky.

Do the first steps, it should cover your problem.
