I've got a personal laptop that I'm taking to work this week for a training course. They recently added wifi access throughout our site at work, but it's pretty strictly locked down. Need a special password, etc. For a personal laptop, I was able to get the weekly visitor password. IT also gave me the visitor username, the SSID, etc. However, my laptop won't even see that a network exists! It's got the intel 3945 wireless A/B/G chip, so it should handle anything. My axim can't see a network either. Others with company laptops worked fine, so I know there was a signal. And my laptop works flawlessly at home on my G network, as well as at other sites.
They walked me through setting up the SSID and everything so it should auto-connect to the company network, but it just couldn't see it. They couldn't help any more because it's outsourced so they can't get beyond their scripted answers

Any suggestions?
