I have what you have; D-Link 802.11g wireless router (DI-624); have three ThinkPads connected wirelessly; two use D-Link PCMCIA wireless cards, one using a Cisco card.
First hint: it shouldn't matter, BUT........pick a brand and stick with it across the board unless you're damned good. IOW, use D-Link stuff, or all Linksys stuff.
If you have specific problems, FReepmail me and I'll see if I can help you.
Thank you. I've returned the two wireless systems that stopped working. What brand do you recommend that I buy?
"Pick a brand and stick with it across the board..."
Good recommendation. I admit I make a living doing the opposite.
A bit stressful. But you do learn alot. Sometimes way more than you ever wanted to know.
