Linksys WUSB300N-RM (WUSB300N-EU) Pre-802.11n Wireless Adapter

I purchased this product installed it it connects fine works great but.. The speed is no where near what they say. I'd like to know if those who connect and say there getting 270mbs have actually benchmarked that? The number the systray icon gives you of 270mbps is a nice warm fuzzy feeling but its a lie. The best speed i could get after techsupport calls and a few tweaks was 47mbps. So yes its faster then my wireless G card that only benchmarked out at 20mbps but its still only a fraction of the advertised speeds. My only hope is linksys will put a new driver or firmware out for it or something. IF they said it was twice as fast as my 54g (even that never went 54) and i purchased it I'd give it a decent rating. But since they said it could do up to 300 I'd expect it to come maybe someone close to that figure heck 100mbps would even be nice.
