I purchased this adaptor for my laptop from amazon for $34. It works well but it says under Speed, 150Mbps. I know that is only the speed it can handle. What bothers me is that the specs on it say it connects at up to 300Mbps. I purchased a different USB Adapter at Wal-Mart(A Belkin) which is also an N adaptor and it runs at 300Mbps when connected....So far it is an excellent connection but I have only been using this new SMC adaptor for about 1 hour. I didn't install the software and just got the driver off the CD which I usually do since I don't like extra crap on my pc that isn't needed. I would rather use windows for my wireless network. Maybe I will try the software but I don't really see a point in all that extra crap it contains,
SMC didn't even have the driver on the website,
I just installed the driver on the cd, and now also I got a new driver from Windows update. Sill I don't understand why it says 150Mbps and not 300Mbps....
