That is a good buy but I can never get into this site. Always tells me they are busy. I would like to grab one for a spare and to get the windows 7 drivers. The drivers for windows 7 are hard to come by and I have not located them yet.
I have been testing my Pepwave mini surf next to the Alfa this morning. The alfa has the best receiver. I have been using this Alfa for a few years now and is best money spent on wifi stuff. Don't waste your money on a two watt version. I have tried them all. The one watt version is best deal. Two watts will not extend the range because you can not see any farther out there than you can with the one watt unit. If you can't "hear/see" what is out there then you can not "work" it. The one watt unit is worth a little more than the 500 mw unit.
So, If you can get on the site and need something like this, grab it.
I will keep trying.
Might use another laptop.

Dan,
If you want drivers:
URL<http://www.alfa.com.tw/in/front/bin/ptlist.phtml?Category=105397>
If you can't make that work, let me know. I could send you copies.
I have a new 036NHR, I got it because my son didn't want to let go of the 036H.
Well, I just got it back this weekend and did a comparison before it went out on loan to the SIL. The receiver of the NHR is hotter, but I am not at all sure it is enough more sensitive to really do any.

If I didn't already have two of them, I'd sure order one (or more) of
those. They're as good as we all claim.
Which reminds me of something I learned recently: They were originally
sold as 300 mW transmitters; then the ads went to 500 mW. Now they're at 1
W. What I learned is the the Alfa web site has drivers which supposedly
increase the output of those older units to 1 W. Now don't get too excited
about that -- it's only half the story (the easy to advertise part). The
sensitivity of the receiver section is just as, or more, important and it's
probably not affected. That long antenna, and where it's placed is as
important. With my first purchase, I bought a 25' BOOSTED USB extension
cable. With that, the Alfa can be placed near an opening to the roof so
the antenna, with its necessarily short cable can be placed high outside.

You can also replace the 5 dBi antenna with a 9 dBi. It is just a little longer antenna. It is on Amazon for about $8.
This will also increase the range for you.

Yep. You want a good antenna free and clear of walls, microwaves, windows, a
stack of toilet paper, tree leaves with dew, and just about anything else
you can think of for good connectivity. Line of sight is a poor way to
express it but it comes close. When I first started setting up wireless
networks I learned of the "four wall" limit. It is still as true today as it
was back in 1998 when wireless networking hit the airwaves in this country.
Each obstruction in that "line of sight" cause degradation of the signal no
matter how close you are.
In the 802.11B days, 300 mW was satisfactory. Then came 802.11G and 500 mW
became advantageous. Now, with 802.11N, 1 W should be the norm. Anything
less is weak.

In 1999 I set up a 67 node network in a hospital. They wanted one short directional shot across the street to another building that they owned about 300 feet away. They could not right of way for a fiber run there. I told them where to put the transmitter on the fourth floor of the main building pointing to the one story building across the street. They overrode me on the location and ran the shot through the tree across the street instead. I told them that come spring they would loose the connection. It made no difference. They did it anyway.
Guess whose pager went off while changing planes in Honolulu airport headed to Maui in early March? I called them and sure enough the link across the street was down. I told them I was working with another client and would not be back for two weeks. At my recommendation they managed to move the radio bridge themselves to where I told them originally to put it.
The point is a little thing like leaves on a tree will block the signal. While concrete without steel rebar will pass it fairly easily. I had no problem passing through 2.5 feet thick concrete in a basement of a 6 story building built in the 1930's without rebar.
All you can do is get a superior client adapter and antenna and then position it to see what you get. Sometime moving the antenna a few inches left or right or up and down is all you need to make it work.
I have pulled 9 miles reliably for a county government complex with clear line of sight. Good communication at this frequency with it's very low power restriction actually requires more than clear line of sight. But for what we are doing, if you can see the Access Point, you should be able to work it. Do not worry about the power rating of the device. It will not help you to boost the power unless you can do it on both ends. A good signal one way and a poor return will not work.
As the hams say. You can't work them if you can't hear them.

I quickly picked up a holder - definitely a good idea.
But the shipping was 3bux more than the clip.
Oh well.

From my experience most of these sub $100 wifi range extenders all use the same chip set so they all are quite similar in performance. Most of the difference is attributable to the antenna and cable (if any) between the device and the antenna. For best results, use an external antenna that is mounted as high up as possible. Fasten one to the top of the crank up over the air TV antenna if you can. The more expensive units either employ a reprogrammed wireless router (ala Jefatech which treats the supplied commercial router as a Linix computer which they reprogrammed) or a marine grade radio repeater. All will work within the bounds of the limited range of wifi signals that are easily blocked by most anything between your antenna and the source antenna. Make sure the drivers supplied with whatever unit you use are designed for your computer OS and they come on a media form your computer can read. On one version of the Alfa unit I tried the MacOS drivers were supplied on
a tiny cd that would jam the internal cd mechanisms in most Macs. The version available for download from Alfa was a couple of MacOS generations back and required hacking at the command line level to get it to install. Hopefully the newer Alfa units come with more rational software.

I wish a bunch of us would be close to each other so we could save shipping on that little holder. That is a good thing to have. I use velcro to hold mine on when I use it. As I have already stated, this is best money spent if you want to reach out and grab wifi signals. At conventions the wifi can be weak at times. This little machine will reach out and grab that signal. I have 100s of dollars invested in wifi equipment. This is a great device. I am now testing the little Pepwave wifi repeater. It also seems to be a super duper little gadget. I got mine from 3gstore.com for 70 bux. I will say this, the reciever in the Alfa is as good as the Pepwave repeater.
