Salut QueenIria, what you have to do is to let the router assign some IP to computers that don't want DHCP addresses by not allowing the router giving IP addresses from 192.168.0.2 to 192.168.0.155 which is the range the router understands.
That means you should set start IP to something like 192.168.0.10 to end IP 192.168.0.155. That means you can give a static IP for your computer (in your windows xp config) from 192.168.0.2 to 192.168.0.9
Is that clear?
Bonne chance
