I have what I think is a pretty quick question but for some reason I've been unable to get the search function to run this morning - not sure if its an office firewall thing or not. Looking to buy a wireless adapter to hook up my HR21 to my router. Nothing fancy, just something that will work. Will possible have an XBOX 360 in the future so if it was able to take two inputs that would be great - but not necessary. I assume this is something that can be just picked up at a place like Best Buy? Specific brands/models appreciated.
