Wireless "limited or no conectivity."

I've had my Thinkpad T43 for a little over a year now, and my suite at school has a wireless router connected to someone else's computer. I'm fairly certain that last year, it worked fine, and I could get a connection and everything. This year, it's a different story.

Each time I connect, I get no connectivity (but I am connected, and the signal strength is strong). When I renew my IP address, it fails. I had problems refreshing my DNS Cache, but I solved that by fixing a service. I've already applied the winsockXP fixes, and still no gain.

One of the strangest things is that it is ONLY this router that is failing me. The school's access points are fine, as well as my wireless router at my house. What's more, is that I and my roommate are the only ones who can't connect to the wireless router. There are 4 others who can.

I believe the router is a D-link, but I don't know the exact specs.

Grumpy asks a good question that I will ask more generally...

How is your suite-mate's router cabled into the schools' network?

Also, unless there is some reason your suite-mate wants to create a separate sub-network, the router should be put into access-point mode.

Finally, make sure he does not have MAC address filtering enabled.

Most laptops have 2 wireless utilities. The built-in Windows one and the one from the wireless adapter vendor. Have you tried switching management utilities?
