Internet Validation

My MN-500 base station will not validate my active
itnernet connection. MY laptop says i'm connected to the
network but will not let my access the internet through
the base station. My desktop computer with the base
station IS connected to the internet. I don't know why
this won't work and Chris H already gave me a link, it
helped sort of, but the base station still will not
validate the internet connection. I'm running Win98 and my
cat5e cable is connected through a USB adapter.
