OK one more suggestion. Try right click Uninstall the Network Controller in Device Manager, and then right click on any device and Scan for Hardware Changes, or just restart. It may correctly detect the device this time...

did you ever get this to work - i have the same problem with the yellow exclamation next to the network controller in the device manager and no wireless connection???

i found out what network adapter was in mine by going to:
and then searching for the model number of my laptop eg 2525y8e - it then gave the spec of what it might have... realise you have probably sorted this now - but just incase anyone else gets stuck and comes across your post
in the end i downloaded the drivers from the intel website and uninstalled thinkpad vantage connections and let windows manage my network connections which did the trick - but would be interested if anyone else overcame this problem and how...

Can you please let me know how did you “let windows manage the network connection” I have a similar problem with Thinkpad Vantage connection” I already uninstalled it, but I am unable to let windows XP manage the network
Any help is appreciated.

Hey, ran into the same problem while I was working on an X40 for a client.
None of the 3 drivers listed on the support page worked, I opened the thing up and got the serial off the card itself, plugged it into google. Got this other thread
And followed the link to the other driver listed even thought it wasn't on the page for X40 drivers.
I uninstalled the "Network Controller" and installed the driver and the wireless card showed up. I just checked the page for the driver and the X40 is listed under the models; I don't really understand why the driver isn't on the actual X40 page and I don't know how many other X40s have the same card in them but it is definitely a possibility if you are having this problem.

I had an issue with my X40 not recognizing any of the Windows XP wireless card drivers available through the Lenovo site. The only Ethernet driver available worked, but none of the three wireless drivers did. Worse, I couldn't even tell what card I had. The device manager only listed a "network controller," or something to that effect. Anyway, long story short, I went to the Intel site and downloaded a legacy wireless driver (the same one works for a bunch of different cards). I didn't install HotKeys, Access Manager, or Power Management, or whatever they're called. My card now works fine and I just manage the connections with Windows. My card turns out to be the Intel 2200BG.
Also, I don't think X40's have this option, but make sure you don't have your wireless card disabled by an external switch. My Z60 and wife's X200s have these switches and they can make you go crazy trying to figure out why the connection isn't working...
Hope that helps. I'm posting this on all the X40 threads regarding wireless issues because I was so flummoxed and annoyed by this stupid issue.How can Lenovo have ignored this for so long? Pathetic.
