T41 Wireless browsing problem

[Dotty]

My T41 says it's connected by WIRELESS but I'm unable to open web pages. The Device Manager states the Intel(R)PRO/Wireless LAN 2100 3B Mini PCI Adapter is working properly.  I have not had any problems connecting by Wireless before, and this problem has only developed recently.  I have not done any changes to my ThinkPad. 

Any ideas would be appreciated.

have you tried to connect to another AP? I remember having issues with certain AP's on my T60 a few years ago.

Can you do anything online at all? Like ping webservers? Connect on MSN? Do you get an IP assigned from the Wireless network, or do you have a set IP-address on the computer?

Most likely this is a misconfiguration somewhere, and it might just as well be in the software, as problems with the negotiation between the AP and the Wifi-card.
