Product Description

lease note the strength of the reception also greatly depends on the area this is operating in, this item cannot transmit through thick walls the same as in an open area, all claims here are for open area, please consider this when making your purchase.

You asked for STRONGER WiFi and Extended Range and here it is. We have combined this high power Wi-Fi adapters with a powerful +9 dBi 15' 2.4GHz Hi-Gain folding antenna. Estimated range is (depending on environment) 1.2 mile (2km). It is compatible with almost all laptops and desktop, PCs and Macs. This kit also includes two antennas- one mini 5 dBi gain travel antenna, and one high gain 9 dBi antenna, as pictured. It is perfect to travel with and weighing less than 2 ounces and measuring 3.5 x 2.5 inches in size (8.5 x 6.3cm)

This has a stunning 2000mw output power. So if you are looking for a device to connect to an outdoor 2.4 GHz antenna, such as on a boat or an RV, this is a perfect solution. Because this is a USB adapter, it works on any computer that has a USB port. this also works with Windows Vista, Linux (kernel 2.6.6 and later) and Macintosh (OS version 10.4).

Very nice device!!

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.

Has a few flaws but worth the money

Reviewed in the United States on March 9, 2015

Verified Purchase

I love that I have this product, and it is inexpensive for what it is. It does have a few flaws. The strength and range are somewhat inconsistent. Sometimes it will pick up 40 networks in my neighborhood, and 30 seconds later it may only pick up 15-20. I use it to share my neighbor's internet (with permission of course) and his house is across the street and 2 houses over (About 800 feet). While this antenna will pick up the network 98% of the time, sometimes the signal strength is 85% and sometimes it is 54%. It works better if you put it outside, but please understand it is in no way water proof. I had the Alpha 1000mW antenna which worked fairly well until one day is just broke. This one seems to be better quality and is definitely more powerful. This unit actually works the best with the 7dBi panel antenna than with the 9dBi that comes with it. My other gripe is the software. I installed the driver and the utility from the included CD. The utility does not automatically start and open when you plug the antenna in each time, as in previous versions, which is kind of annoying. The unit does work pretty well most of the time, although when the network you are connecting to has alot of traffic, it will disconnect sometimes. So yes, this product is worth the money since it is fairly inexpensive, but you have to be willing to mess with it sometimes, kind of like TV rabbit ears, when it works, it is great.

Alfa AWUS036NH adapter kit

Reviewed in the United States on December 13, 2012

Verified Purchase

I have this adapter as well as Alfa's AWUS036H, and was curious how they performed compared to each other, so I connected both and put them within one inch of each other. Both adapters faced the same direction and both adapters had the ARS-N19 9dBi antenna attached. I scanned for networks roughly a dozen times, so this test isn't scientifically rigorous, but rather informal. OS used was BT5R3 GNOME up to date as of September 2012.

Pros:
The AWUS036NH can pick up APs that are further away that the 036H can't. In some tests, it picked up two APs that my 036H didn't.
Range is better, but I can't be certain it's anything close to double the range of the 036H.
This adapter can pick up 802.11N networks as well as 802.11G networks.

Cons: Signal strength is usually slightly worse for the 036NH than the 036H.

Home network signal strengths with both adapters plugged side by side:
AWUS036NH: -39dBm
AWUS036H: -26dBm

Nearby AP:
AWUS036NH: -76dBm
AWUS036H: -62dBm
(Note: this isn't always the case. Sometimes, the 036NH had a better signal strength than the 036H).

The AWUS036NH failed to pick up APs that the 036H did in some tests (one AP @ -68dBi).

I don't understand why an adapter with twice the power would have poorer signal reception, nor do I understand why it picks up some APs sometimes, but not others.

I'm less than satisfied with the product, but I can definitely see value in the product; a shorter ranged WiFi adapter for 802.11N networks.

c'est la deuxième carte wifi de ce modele que j’achète. très puissante elle me permet de passer au travers de murs avec armatures métalliques et sur de plus longue distantes.
Il parait que c'est la carte préférée des hacker, vu les antennes utilisées cela ne m’étonne pas.
