Summary: This product should really be a 5-star product. The only reason that I am not giving it 5 stars is because there are no drivers to support windows vista or later. Tested on both windows vista and windows 7, both cause blue screens like crazy. This product works amazing and does not disrupt the stability of a windows xp machine.
Summary: Surprised this only has a few reviews... but this thing is increased my signal and available networks significantly. If you want a great adapter capable of packet injection/security testing or just to get online, this is it!
Summary: I bought the Alfa AWUS036H after reading all the great reviews. I LOVE this wifi adapter. Works in all types of operating systems. All the drivers are online at the Realtek website. I had to download it for Windows 7 x64 because the CD did not have it (this was not a big deal at all). I prefer to download drivers from websites since they are always up to date. I used to pick up only 2 access points with my Belkin N USB adapter...this thing picks up over 10 !!!
Good antenna with excellent range, but many problems when used as access point in XP SP3 and Windows 7

Summary: I originally wrote a 5 star review for this product, but am reducing my rating to 3 stars. As near as I can tell, it works great for connecting to other networks. But in access point mode, I have had constant problems with it. After a random interval, no device can connect to it anymore and I would have to "repair" the connection in XP. It would work again only to go out a little while later.
Summary: this adapter outshines linksys adapters by leaps and bounds goes from 2 bars to a minimum of 4 often hitting 5bars well worth the money this is my 4th one i bought for all the systems in my house . a must have for long distance wireless connections .4 bars through 2 walls and 200 ft away.
