Hey. I have the Asrock Professional Gen3. I'm running Windows 7 Ult 64. Different board than yours, but avoid this USB wireless connector:http://www.newegg.com/Product/Product.aspx?Item=N82E16833166056&Tpk=RNX-N180UBE
Absolutely, positively could NOT get it to work (neither could a lot of other people).
Then I got this USB wireless and it works great: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=3173666
Worked perfect right from the start.
I also have powerline networking running on this board with these:http://www.newegg.com/Product/Product.aspx?Item=N82E16833156283
Initial set up of the tpl303e2k was a bit of a problem (read my newegg review for the whole story) but once I got it sorted they have been great.
Note: You won't get anywhere near the advertised speeds with the powerline networking, and if you, say, turn on an appliance or stove, dishwasher, etc. it can impact your speed / quality.
