[Eratosthenes]

I use the linksys wrt54g and have installed about a dozen of them various other places. It has b/g wireless and 4 wired ports. It also has a strong linux-based firewall that is very flexible and very secure. They usually cost $49 or $59 at best buy, compusa, etc. You can get less expensive wireless routers, but I think these are worth the extra 10 or 20 bucks.

Don't forget to: enable encryption (wep) and change the password.

You can also download replacement firmware for the wrt54g. That firmware allows you to adjust the wireless broadcast power. I use that feature to lower the power to the lowest reliable level so that neighbors and war drivers have more trouble connecting to my access point.
