ALFA Network Long-Range Dual-Band AC1200 Wireless USB 3.0 Wi-Fi Adapter w/2x 5dBi External Antennas - 2.4GHz 300Mbps / 5Ghz 867Mbps - 802.11ac & A, B, G, N

This product is very good for pentesters it helps every single programs and windows Linux and security testing features with it.

Got this product delivered very quickly. Now all the computers and laptops in the house are connected via WiFi. Bought this USB WiFi adapter for its range, as my wireless router is 2 floors away, and in the diagonal position through the structure of the house. it's very easy to set up. Just installed the driver and plugged in this adapter, and hey, it worked on the first connect. Reception signal reading is much than the laptop and two other USB adapters without the big antennas. So now I can crank down a bit of the transmission power of my wireless router and still keep computers in all rooms connected without any issue. Recommend it (generally with big antennas) if you need to get reception through several floor and walls. Hey if you still have issues getting signal, the flexible antennas are there for a reason. Imagine a huge donut shape radio transmission cloud around the antenna, and make sure your wireless router is in the cloud. Hope this helps.

Es buenísimo, detecta una asombrosa cantidad de redes que mi portátil no puede.

I bought it about a month ago and have had no problems with it. It works well, and hasn't been giving me any problems lately. That's the short version. Below is a long version for anyone who really wants more information. (By the way, I would definitely recommend this product.) Anyway, on to the long version. At first I was a little worried about buying it given some of the negative reviews and all of the driver problems. I'm running a Win 8.1 machine. But bought it anyways just to try it. The shipping was great, I received it in 2-3 days and the device was completely intact and new. I tried just plugging the adapter and letting Windows auto install the driver for it because people have said that the driver on the CD didn't work. Windows did download a driver for it, but the driver didn't seem to work. It could see Wi-Fi networks around my house, but I couldn't connect to them, so I used the CD to install the driver and the Realtek USB service (after uninstalling the old driver that Windows downloaded). In the event that you do plug it in and the driver installs and you want to uninstall it, unplug it, go into device manager, and uninstall the driver. You can also try keeping it on there, but I didn't want to risk messing something up. In retrospect, the reason that I couldn't connect to any Wi-Fi was probably because the Realtek USB service is required. Edit: After a bit of use it seems that it is not required, but I like the service. So, just for reference, every single step I took once I put the disc in is as follows (which means a very long list. In reality it isn't as bad as it seems, just a lot of clicking. You can also skip it and just get to the overall review.): 1. Opened "File Explorer" and clicked on "This PC" in the Navigation Menu (Also known as My Computer on older systems). 2. Right clicked on my DVD drive and clicked on the "Open" option. 3. Double clicked on ALFAINSTALL.exe (by the way, I remember reading a review that said a user's manual was not included on the CD. I found one in the "doc" folder on the CD.) You could also let it auto run. 4. When it opened, there were three buttons. One was "Browse Disc" and the other two were for selecting the product you had. I clicked on the one that said "AWUS036AC", which is this product. The other option was a slightly different adapter. 5. When I clicked on it, it asked me which driver I wanted to install or if I wanted to view the user's manual. (The three drivers it listed were Windows, Linux, and Mac. Not sure how well the Mac works, but I will look at the Linux and edit this review later.) 6. Clicked on the "Windows Driver" button and it came up with another list of buttons that asked if I was using XP, 7, or 8/8.1.) 7. Clicked on the "8/8.1" button and then hit "Yes" when UAC popped up. 8. Next it had me install the Realtek USB Wireless LAN Driver and Utility. (Which is a fairly nice piece of software by the way.) 9. Hit "Next" on the screen that popped up. 10. It came up with a bar that said it was installing and then Windows asked me if I wanted to install the device software. Checked the box asking if I wanted to always trust software from Realtek Semiconductor Corp and then hit install. 11. It installed and then asked if I wanted to restart my computer now or not. I hit "Yes, I want to restart my computer now." and then hit "Next". 12. After my computer restarted I hit the "Show Hidden Icons" button on the right hand side of the taskbar, clicked on the "Realtek USB Wireless LAN" (hover over it to see the name) which opened an application window. 13. I then plugged in the wireless adapter and the application automatically found it. 14. I clicked on the "Available Network" tab and it showed a list of networks I could connect to. 15. I clicked on the network I wanted, typed in the Network Key (password), hit "Okay", and it worked perfectly. I tried it on 2.4 GHz and 5 GHz and both of them work fine. If you have any questions, please ask in the comments. So far, the signal has been fairly consistent. It is usually around 95%, but goes between 90 and 100. For some reason it also occasionally freaks out and drops to 75% or 80%. But maybe that's because I am using USB 2.0 instead of 3.0 so it's not getting the same power it would on 3.0 (I have no clue so I am making a slightly educated guess)? I don't have good internet, so I can't speak for the speed. Also, I regularly use the 2.4 GHz band because 2.4 GHz is an inherently stronger/farther reaching signal. At average of 95% I am around 30 feet away from my router, with a few walls in between. I have noticed that the percentage doesn't really change much between 20 and 40 feet. It stays in that same range I mentioned earlier, and it still does the same freaking out thing. Just so everyone knows, I am using a Wireless-N network on the 2.4 and AC on the 5. I am also using a USB 2.0 because of the orientation of the USB ports on my laptop. It's light enough that you can also stick it strait into your computer without harming it or the USB port. Pros: Works on Windows 7 and 8.1 Good signal reception and transmission Doesn't cut out The Realtek USB Wireless LAN program is pretty good It supports USB 3.0 It supports AC wireless It operates at 300 Mbps instead of 150 Mbps It comes with a USB dock that has a 4' USB cable No problems with shipping. It came in 2-3 days. It is as it was advertised You can use different antennas if you want, maybe a lower or a higher dbi antenna Cons: Sometimes the installer disc ships with old drivers Can use without the two antennas, but not very good wireless The dock is 2.0 Occasionally freaks out and drops about 15% in signal strength 10" tall when in dock and about 8-1/2" tall when in computer Requires the Realtek Software to operate well At some point here I will test it on Linux and edit this review to include info about how it works.
