Summary: I was able to install this adapter on a desktop PC with Windows 7 OS, and it works well. Unfortunately it would not work on two very different Windows XP desktop PCs. On them the installation disk ran forever and had to be stopped.
Summary: This little wireless works as well as any other. We needed it in a pinch and it turns out to be just fine. And with it being so little, it certainly doesn't get in the way of anything else. Good bang for the buck here.
Summary: one star because it does work if all else fails you will get to the internet.. however it will be so slow you won't even won't to use the internet. I just tested on 4 devices doing speed tests. wired the 3 computers I used were all pretty much identical at 54down/4up.
Pros: as a last resort if all else fails you will get a very slow connection to the internet.
Cons: while it does technically work. it performs terribly. I have tried using this adapter on 3 computers now and every time the signal is only so-so and the connection speed is almost non existent.
