You might have a vlan problem. I'm not sure if this applies to the WRT54G, but some routers dont show wired computers from wireless and vice versa. Even though they are on the same IP range, they may be on seperate virtual lans which would explain them not showing up
Bob, IRQL_NOT_LESS_OR_EQUAL is a driver problem, usually not ram. The crpatacular NVIDIA WDM drivers or firewall program kept making my rig go tits up. (never cared to mind out which driver it was)

BTW its really really funny. Linux...
I aquired an old computer, about 2 years ago and installed ubuntu after a few days of research, as I knew nothing. This was done downstairs in my parents office, where the router was.
