What router do you use?

I use the belkin G.

I use a Netopia provided by our ISP. Has mac filtering and special cards that can bypass this. We use to have a Linksys which did very well. But it's pretty old and when we moved our ISP recommended a new one. So we just rent one.

Depends on the type of work I am doing... I have used Linksys, Belkin, Netgear, etc.

I make sure that it is WPA2 capable, MAC filtering, and has the capability of notifying me when a rogue device tries to connect. I have even tried a link sys N router. I switch routers every couple of weeks since it is always on.
