I don't yet have a Wireless N router (probably later this year), so I cannot test the Wireless N speeds obtained this adapter, so you will need to check other reviews for that one detail.In my bedroom, the wifi coverage from my router is weak and patchy - as received by the built-in wireless on my laptop - so I thought I would try using this adapter instead.The adapter comes with a USB extension, which I think is very helpful for troublesome locations, as you can experiment with different placements and escape "dead zones".It also includes a small CD with complete drivers.  For any other device, the drivers could be on the web... but... if you bought this adapter because your internal wireless adapter is dead, then you can't download the drivers, because you need this device to get on the Internet !  So, it is good that TP-LINK has considered that possibility.  Of course, it's also simpler to just insert the CD.  The only flaw in this system is that some devices have no CD drive - then you will need to use another laptop or PC to either transfer the CD's contents to a USB flashdrive, or else download them from tp-link.us web site and transfer to a USB flashdrive.Anyway, the install was very easy, and all I had to do was click on my router's ID, enter my password, and it was up and running.The wireless G performance is excellent, and the USB extension allowed me to find a point in my bedroom to position the adapter, that always has good wireless coverage from my router, so everything is cool now for using my laptop in bed. :)So far, I've had good experiences with TP-LINK products.  If I change my mind, I'll come back and update the relevant reviews.  When I get an N router, I'll update with the N performance too.
