More good suggestions - thanks!
Ky - great idea! Our newer dell laptop has that wifi light and this older one i'm trying to resurrect has a switch (Fn F2). Unfortunately that has no effect on making it see the router.
I went to the Dell site and downloaded drivers that appeared to be more recent than the ones on the disk. Installed them, no change.
It appears the network cards are installed properly with the appropriate drivers.
At one point it actually found a wireless net - not ours 2 feet away, the neighbors. I logged into it and it worked. I logged out and was unable to replicate whatever i did to find it before. But at least some indication the wireless card works.
I'm now considering whether i should shoot it with my shotgun or pistol. I'm leaning toward the shotgun as being more satisfying.

I've spent several hours yesterday and several more today trying to get this to go. My time is valuable and i think it may be time for a new computer. This laptop is over 5 years old and that is pushing it for any portable - especially one in the college environment.
Maybe this is the excuse i need to get one of those netbooks... hmmmmmmmm
Thanks again for the advice and please share anymore ideas - i haven't given up on this thing yet!
