Linksys - WRT54GL - says linux on the box
Put tomato firmware on it.
My uptime is 81 days and counting... since I first plugged it in.
It's rock solid. I bought it after my WRT54G started crapping the fuck out. Cisco bought linksys and fucked with the wrt54g people complained and out came the amazing
WRT54GL.
Starts at $58 it looks like, but its only G-wireless if that's important to you.
I have three desktops, laptop, and 360(broken now) on it and all worked flawlessly.
Tomato firmware rocks too.
TONS of cool features that become available.

From tomato: "It features a new easy to use GUI, a new bandwidth usage monitor, more advanced QOS (quality of service) and access restrictions, enables new wireless features such as WDS and wireless client modes, raises the limits on maximum connections for P2P, allows you to run your custom scripts or telnet/ssh in and do all sorts of things like re-program the SES/AOSS button, adds wireless site survey to see your wifi neighbors, and more." and
IT"S FREE.
