I use this wireless adapter with a somewhat elderly Windows 7 laptop. He was immediately recognized and was used quickly and without problems. Previously I had the laptop because of the location on a regular basis reception problems and only unstable and slow Internet connection. That's over now, thanks to the adapter, there was an almost dramatic improvement and the use of the internet makes then again on this computer fun. That's not the einzge household computers, but one can actively engage him again in the network.
Overall, this is a very good and well priced attractive opportunity to spice up his home network or to bridge larger distances to the router. That's me then 5 star and worth a buy recommendation.
