My linksys WRT54G is not connecting to the internet after being rest to factory settings

Who is ISP?
cabel or ASDL?
how do you know it's not connected?
does routers WAN light come on?
are you even plugging a PC into it?
does the router network indicator lights light up on the ethernet ports?
are you getting any network errors/warnings PCs connected?
how old is the kit?
has it ever worked?
