I am using a linksys WRT54G v 1.1 firmware 4.20.7. I am unable to connect to an IBM Thinkpad with integrated wireless card: IBM b/g wireless mini pci adapter with latest drivers. I have used WEP PSA, and disabled. I have tried to use IBM Access Manager, and without, still unable to connect. IPCONFIG shows "no operation can be performed while media disconnect". I was previously able to connect on an older laptop using a WPC54gs card. In addition, I am unable to change channels on the laptop, and so I have tried various channels. Please advise, and thanks in advance.
