Wireless adapter problem

[dr_annoying]

OK, so I just bought a TP-Link wn822n to connect my upstairs desktop to my downstairs router via a repeater, but once I installed the driver and the utility, the utility's not letting me do anything, it only lets me select which adapter and that's it; it's not even letting me switch any of the tabs from advanced and all the settings in the advanced tab are grayed out.
I know it's not the adapter itself because I'm using it right now on my laptop and it's perfectly fine.
My laptop is running XP though, while my desktop's on 7.
Any ideas why my computer's being such a PITA?

quick google... review
The TL-WN822N comes smartly packaged with a 1.5m USB cable, quick installation leaflet and an 8cm mini-CD with the drivers. I tried plugging it into Windows 7 without the drivers installed to see whether Windows 7 could identify it, but no joy. Even worse, the drivers on the CD were unsigned, so I grabbed a set of newer WHQL-certified drivers from TP-Link's website. There's an optional client utility included for use with XP, but this doesn't install for Windows Vista/7.

So, Uninstall everything.
Get new drivers from webpage.
Do NOT install the "client".

tried uninstalling all drivers installed from the disk and let windows find and update drivers for the device?
