I bought this to go with my new wireless N router. I was kind of bummed they do not make one which can handle the full speed of wireless n, but i figured half the speed would be a great improvement, plus the range increase would also be nice. i just opened it today and it is really really small. plugged it in and win 7 installed some generic driver before i could stop it, but it did not make a difference. followed the directions which came with the adapter and in about 5-10 minutes, i was connected. a few small items to take note of. you can use the win 7 wireless tool to connect to networks, however, whenever my computer shut off, went to sleep, etc, it would not auto connect (even though i told it to). turns out you have to use the airlink tool which gets installed to create a profile and then set that profile as the default profile. then, whenever you restart, turn on, wake it up, etc, it will auto connect without any issues (though the airlink tool does pop up every time).
the transmission speed works best when the router is set for full wireless n mode (some routers have a mixed mode). it connected in this mode, but the speed was half its max. setting the router to full wireless n resulted in full speed on the adapter side. other than that, it really works great. our internal connection to our network drive is much faster (transferred a 600MB movie in about 2.5 min, which used to take 5-6 min. the range has also improved (through 2 walls, i was still at 80% strength and 120 speed).
would def recommend.
