How to buy a USB Wireless dualband device that works?

I get that it has to be on the list and the right version, but two purchases in where I could not see version was wrong till I opened the box, I am wondering if there is any link someone can post or a definitive way to know i am getting the right USB device?

The list that you refer to is the only list available. You could ask if you may see it in the shop before you buy it to determine if it has the correct version (on the usb wifi device itself or on the box).

Thanks. Too risky and expensive. Will wire my house instead. I have always said wireless is not ready for prime-time, this is just another confirmation. 

I’d like to see a WD engineer explain why this needs to be a problem.  Any clarification would be helpful.
