Joseph Terranova said: "Linksys routers have a nasty flaw: they keep track of all connections for days. So if you're using something that has a lot of connections, such as p2p or freenet, it bonks fairly quickly. You might want to try looking for an alternative open-source firmware for it that fixes the problem.
Well, that certainly doesn't sound good. But while I'm a fan of open-source, I think mixing it with old hardware might lead to even more difficulties. I'd rather look into D-Link, Netgear and Belkin. What is everyone using? What model works well with Freenet in a home environment?
