Have I been sold an AR5006X instead of an AR5006XS, and what's the diff?

I recently bought an AR5006XS from Ebay. It works fine, and connects to my netgear router (windows says) at 108Mbps. In Device Manager, it's only listed as an AR5006X, and looking at the inf file, the driver definitely knows about AR5006XSs. When I install the Atheros utility, that says it's an AR5006X too, but it's a driver from June(ish) 2006.

The card is a weird brand called 'ASKEY', and has the model number WLL4070-D50. When you Google this, you get mostly Japanese sites, some of which suggest the card has 'XS, some only 'S.

Vendor ID 168C Device 001B, again inconclusive.

Is the Atheros util allways right? Is there any way to find out for sure?

Thanks!

the main difference is the xs model supports "super ag" at 108mb the standard x model does not and supports up to only 54mb so if you are connecting at 108 you have the xs based card, they also use different chipsets on them, and have some other smaller differences but you def have the xs model @ 108mbps

 

I'm using a Netgear router, and I just found out that I hadn't enabled the 108Mbps 'super' mode, when the driver said it was connecting at 108. Also it was just windows reporting 108Mbps, not the Atheros util.

I'll mess more with the router and see if windows still thinks it's 108Mbps.
