I wonder if you can help me out.
I am trying to connect a Dell Latitude D410 to a WPA-PSK wireless network which uses AES data encryption. The laptop has Windows XP Pro 32 Service Pack 3 bit OS installed.
It seems to connect ok for a few minutes, and then I will get a notification telling me that it has connected to the wireless network again. Shortly after that it will display the message unable to connect to preferred wireless network.
If I install Windows 7 Pro 32 bit on the same laptop, I can connect to it with no problems?
The laptop is being used in an office and I regularly test other laptops on the same wireless network all which have no problem connecting. We have a network engineer who has assured me that all the network equipment is fully tested and working absolutely fine. We connect all the PCs to our domain, but these issues occur before I connect it to the domain.
I have formatted it twice with Windows XP and same issue occurs each time.
I have even tried using another 3COM wireless card to see if it is the hardware itself, but it also gets disconnected too.
The problem seems to be something that is part of the hardware for that particular laptop. I suspect it may be something to do with the built in Bluetooth.
The last thing I haven't tried yet it to totally disable the wireless in the Bios and see if it lets me use the 3COM card.
Any help or suggestions would be very much appreciated.
