UPDATE: This router has been for me 100% compatiable with Linux. Do note however I don’t manage the router through Linux, instead I use my computer running XP for that. However using Firefox through Kunbuntu Linux, you can still do it. I guess its just easier for me to do on this (my computer running XP) than it is through Linux.
Managing the router by the way is very easy. Just type its IP address in the address bar of a computer attachted to it, and thier a graphical menu you can go through and change your Firewall settings, WEP or WPA settings, and everything else I can think of that you would want to do with your router. Enjoy!
