Highend gaming routers....

[*Xx~Vlad~xX*]

You can take D-Link, Linksys, and many other home brand routers and install a Linux based firmware that will make the device much more robust from all the news articles I have read to support this. I have not tried it myself, but it might be cool (If you have one of these devices already) to give it a whirl.

I have been wanting to try this for a while.
