I had high hopes for this device after having had to use big old cumbersome USB adaptors in the past to get anywhere near a 150Mbps connection to my 802.11n router. I have to say I'm really disappointed in this, the built in 802.11g adaptor in my laptop gets a 54Mbps connection and an excellent signal strength on the floor below the router and 1 room over, this little fella could only muster up a maximum of 50Mbps and even then it fluctuated massively between that and 13Mbps. 'Increases wireless coverage 3 times further' I don't think so! I'll be returning this for a full refund.
