The wifi chip inside my HP Pavilion laptop just doesn't have the range to work outside the house. But I certainly won't buy another one just for that!
This USB long range adapter allows me to use my laptop wifi connection almost everywhere now :-) I'm very pleased!

4.0 out of 5 stars USB Wireless adapter Jan. 31 2012
The product worked well right out of the box and installation on my laptop was very quick and trouble free. Wi-fi reception was significantly increased. The only negative is that the 9dB antenna is a bit heavy for the very light base unit and tends to topple over if not supported. I should have bought one with its own heavier base unit but this would have meant another connection wire in the set-up.

1.0 out of 5 stars Buyer Beware March 24 2010
By A. G. Smith - Published on Amazon.com
As the happy owner of an Alfa AWUS036H 1000mW wireless adpater, I purchased the Alfa AWUS036NH 2000mW wireless adpater for my second computer expecting to be ecstatic.

Imagine my disappointment when I discovered that the 2000mW adapter has more difficulty finding, acquiring, and maintaining connections to wireless access points than does the less expensive, supposedly less powerful 1000mW adapter.

Regardless of the combinations of cables, antennas, computers, locations, and updated drivers I tried, the 2000mW adapter consistently found fewer than half as many access points and reported far lower signal strength than did the 1000mW adapter.

Assuming that I'd received a defective item, I contacted a customer service agent at DB Roth who politely handled my call and promptly shipped a replacement adapter.

Unfortunately the second AWUS036NH performed just as badly as the first. Since both 2000mW adapters had exhibited the same behavior and the 1000mW adapter performed perfectly (as has been similarly reported by other Amazon.com customers), I have decided to exchange the 2000mW adapter for the less expensive 1000mW adapter.

DB Roth customer service has been extremely helpful. In spite of a brief misunderstanding over shipping charges, Bianca in customer service deserves very high marks.

Sadly, I can't say the same for the Alfa 2000mW adapter.

5.0 out of 5 stars Know how to use a WiFi Adapter Oct. 5 2010
By MitchiN - Published on Amazon.com

I would like to point out to all of those who have been dissapointed by this item and would like inform you on possible reasons you may not experience the advertised range. When it is advertised as 1-2 miles, it means 1-2 miles line of sight. So in other other words you can't just put this adpter in any window in locations that have other houses trees or and other objects in the way of the signal and that includes electronic devices that interfere with signal. The antenna is omnidirectional and you will never get the distance out of it that you will with an antenna that only focuses on less than 180 degrees. A good example to reference would be a satellite dish. It is very possible to get great range from any adapter when set up properly physically and and virtually.
I love this adapter and have been gaining 1 or 2 bar signals on every wireless network that comes up. Also you dont need to have this adapter and the built in adapter running at the same time to get a better signal and most of the time they will somehow affect each other and not give you a true reading.

Unbelievable range and power. Anyone who doesn't love this doesn't know what they have or doesn't know how to use it. Backtrack and 64bit Windows compatible, who could ask for more?

5.0 out of 5 stars Very nice device!! May 18 2012
By Jennifer - Published on Amazon.com

DISCLAIMER:I do not work for Alfa. I am just your average do-it-yourselfer who loves working with Backtrack and Wi-Fi tech/gizmos.

I've been looking for a good strong wireless card for awhile now to use with backtrack. I saw a lot of buzz on the internet about these Alfa USB wireless cards and finally got the spare cash to buy one. It took me a while to decide whether I wanted to get the "confirmed awesome" "B/G" only (AWUS036H) card, locking myself into the soon to be obsolete "G" technology, or if I wanted to try my luck on the newcomer which supports "B/G/N" technology. I finally decided to take the chance and get this B/G/N version.

This card is phenomenal.

Now, for those of you, like me, who are Atheros chipset buffs, fear not. While this device DOES NOT have an Atheros chipset, it is still a great card. I think it is either Ralink or Realtek. I can't remember now, but anyway, I took it out of the box and attempted to install the driver found on the enclosed CD, and like other reviewers here have stated, it was a no-go. The driver installed without error on my PC, but the device will not use it (wrong driver). I am guessing that the issue must be that the enclosed CD doesn't contain a 64-bit driver. So, as I am running Win 7 x64, I went and got the correct driver from Alfa's website, which is the Windows 7 driver package (I guess it contains 32-bit and 64-bit versions of the Windows 7 driver). Got that installed, screwed on the stock 5 dBi antenna first, plugged it in and held the unit in the window next to my computer desk.

The performance at this point is pretty good, as far as just doing a site survey. The card picked up all of the Wifi networks that I can already see with my DD-WRT flashed WRT-54G V8 router + connected Super Cantenna (pointed out the same window), plus a few new ones. This tells me that the Alfa card performs slightly better than my current setup, using just the stock 5 dBi whip, which says alot, but now here comes the fun part.

I then unplugged the unit, unscrewed the stock 5 dBi antenna, and screwed on this 9 dBi antenna that came in the bundle that I ordered. I plugged this thing into the computer and did another site survey, holding the unit in the same window as before. The number of networks it found has doubled. In fact, it was actually picking up the WiFi network from an elementary school 7 (city) blocks away from my house with 2 out of 5 bars! I kid you not, and I live in a city type neighborhood with brick buildings/houses. I DO NOT have line of site to this school by any means.

So if you are still on the fence about buying one of these things, get one, however I would definitely suggest picking up the bundle that I got that comes with the laptop lid clamp (attaches to the black case where its suction cup would go) and the 9 dBi antenna. You can't go wrong.

CAUTION: The 9 dBi antenna is BIG and has some weight to it. When I screwed it onto the Alfa card, I noticed that with very little pressure on this massive antenna, the RP-SMA connector soldered to the board inside the Alfa card appears to slightly flex, so keep this in mind. If you plan on using this Alfa card in conjunction with the 9 dBi antenna, it would be best to either attach the unit someplace where it won't be touched/bumped/whatever, OR, use a short pigtail between the antenna and the card so that the card connector doesn't have to bear the weight of this antenna, as I have a feeling that if this thing were to fall on the floor with this antenna attached, the RP=SMA connector may break off the unit, and that would be very bad. OVERALL, I would (and have already) recommend this card to a friend. If you are careful with it while using this big antenna, it should be fine.

BACKTRACK USERS: I have not plugged this thing into my laptop running Backtrack 4 R2, so I cannot attest to it's functionality there, but from what I have read using Google, it should be just plug and go (monitor mode, injection, etc.). I'm am still using 4 rather than 5 because my laptop is too old to run Backtrack 5, in case anyone is wondering. Backtrack 4 R2 is just BT4 with a kernel update that allows the required driver for this card to work. From what I have read, the driver for this thing is included in BT4 R2 but IS NOT included in BT4 Final. You will need to upgrade your OS from BT4 to BT4 R2.

QUALITY ASSURANCE: The box to this card has a small sticker in the front that seals the box closed. Look for, and make sure it is intact once you've opened the shipping container, otherwise you could be receiving a unit that has previously been returned (possible defective unit). ALSO, on the back of unit itself, there is a holographic authenticity sticker that reads "Alfa, Taiwan" on genuine units. Look for this as well or you may be receiving a cheap clone.

Thank you for reading.

3.0 out of 5 stars 1 to 2 miles? NO WAY! 400' maybe. March 16 2010
By Richard D. Piselli - Published on Amazon.com

This unit is worth the money if you only need a small boost. There is no way to pick up signals at 1-2 miles away for $50.
It may work at best 400'. I extended the range by putting a water bottle over it and putting it on a 15' pole. Spring for the
optional 15' cord, it's worth it. At 150' I gained 2 bars. The extra larger antenna is trash and weakens my signal. The
photo shows two bases, it comes with one. Very simple to install. It works o.k. and not what they say it does. Go for the
magnet mount, the suction cup is a toy.
