Sorry, but now i'm a bit confused for each machine you describe could identify
Machine #1 vs #2 etc. along with
> The Windows OS and Service Pack level on the machine
> Do you think the wireless manager is enabled on the machine
> Are you using IE7 or another browser on the machine (e.g. IE8 or Firefox?)
> And please repeat which problem occurs on which computer
So then i'll add that (in general)
> A wireless manager should be running on a computer with wireless
> It's the wireless manager's job to scan for networks and, if you configured it to do so, automatically connect to available wireless networks it finds
> The wireless manager runs as a Windows Service
> You can see a list of Windows services by rt click My Computer->Manage->Services
> The native manager in XP, is called Wireless Zero Configuration
> In Vista, it's called WLAN AutoConfig
> Once you find the service you should see its StartupType= Automatic and Status= Started
