Same issue with XP here. I`ve tried atleast a dozen drivers up to now with no success. Under Knoppix (live linux) works like a charm.
PS I got the adapter from an HP laptop, my is Dell Latitude D830. Do I have any chance of getting it to run under Windows?
I had a Dell Studio 1737 with the 5100 AGN Adapter and used the drivers from Intel® Driver Update Utility The adapter worked great with no issues. Here were My Intel WiFi 5100 AGN Connectivity Settings
It originally came with Vista 32-bit. I switched to Vista 64-bit, then later upgraded to Windows 7 64-bit.
I also tried intel driver update. It loaded the latest intel driver. But it just doesn't start.
So the settings are useless.
Is it a wifi card hardware revision problem?
How come it works under linux and not with intel drivers under windows?
This really means that the driver is faulty with this hardware revision.
I bought an intel wifi card thinking that it is better quality (hardware and software). I am now very disapointed.
