As for your question about Linksys routers. I have a WRT54G wireless router and it sucks when set up as a gateway (ie the computer that gives out IP addresses). What I have set up is I got a cheap dynex router and configured my linksys router to be a router (meaning that the router itself gets an IP address from the dynex router).
How I have this set up is I have a cable running from my cable modem to the dynex router's WAN port. I then have a cable running from one of the numbered 1-4 ports on the dynex router going into a numbered 1-4 port on my linksys router. It doesn't matter which number you plug the cable into on each of the routers. I then am able to connect perfectly with my wireless connection. Before doing this, the router loved to kill the internet connection at least once every couple of days if not more.
This solved a major headache, considering my computer is two floors below the router, so I have to go up (and down) 26 steps each time I changed a setting and wanted to test.
I have never had a problem with a linksys router acting as a gateway when it wasn't a wireless router.
Hope that answers your question.
