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

Works on linux

works great, good material very compact

My Wifi Antennas were connected to the back of my PC. And my PC was in a cabinet. Needless to say not the ideal situation for a good signal. The signal would massively fluctuate down to no bars at times. Always stayed connected though. But couldn't even get my full internet speed.I started looking around for Wifi Adpaters so I can place one on top of the cabinet and out in the open. I figured I might as well spend the extra money and get a good one. I also got a new USB 3 hub. And bought a short USB 3 adapter so I can plug the Alfa into it and have it standing straight up for great reception (see attached photo).My computer is on the 3rd floor, and my router is on the 2nd floor in the Kitchen. The signal has to go through sheetrock, marble tile, some thick cork underlayment, and really tough bamboo flooring. It's working beautifully. The signal is rock solid. I'm actually getting faster internet speeds than I even thought I had. I'm only using the 5 Ghz wireless N though right now. I don't have an AC router yet. But since AC works off the 5 Ghz spectrum it should be great too.I should note that my photo shows different Antennas, that's because I had some other pretty robust ones I put on instead of the stock ones. The Stock ones are totally fine though. I'm not sure it mattered, it's just I already had them and the wire inside looked to be thicker, I figured maybe it offers less resistance and that could help. So I threw them on. The stock ones are plenty good quality though and were working great.I wish Amazon would put this one higher on the search results, I had to go pretty far to find this. I almost bought an older one that was cheaper but didn't look as good or have the newest specs.It's USB 3, it's wireless AC, it's the newest version. It works fantastic. Spend the little bit of extra money and get this one.*I'd also like to note that I did NOT install any of the drivers or software or anything on the CD. I just plugged it in and Windows 10 did everything instantly. I'd suggest you also do the same. You should really never use CD drivers or software. It's almost always out of date for anything you are installing. Either let windows do it or go download the latest and most up to date from a manufactures website.

This is a great little product. My old Dell desktop had been Internet capable using an Ethernet cable only, no WiFi. However, it is no longer my primary computer for software development activities. I have a new developer-edition laptop for my desk, along with a large external monitor. The old desktop is still quite usable, but needed to be moved away from a wired connection. So I bought this product. I had bought the desktop system in approximately 2009, and it had had Windows Vista installed. The system had become unusable due to slow response, and I had become disgusted with the poor quality of many Windows releases. So I saved-off a lot of files using a thumb drive, erased Vista, and installed Ubuntu Linux back in 2013. So...back to this product. It is advertised for compatibility with Windows and MacOS, and comes with an install disk for these systems. The disk appeared also to contain a driver for Linux, but I could not install it this way...an error occurred for which there were no specifics. However, I did find instructions on the Internet for downloading a compatible driver, using "sudo apt install..." Something like that. Just look it up if you need to; I don't remember specifically what I did. But it can be done. So I am typing on this system right now using the wireless connection. The system and I are downstairs, but my modem is upstairs.

First I would like to say that it is possible to get this product to work on Linux, but it definately is NOT OOB supported! Even the box says Linux kernel 2.4 or more recent, which I doubt that is true...There are different drivers for the Alfa, some are hacked or forked and those simply do not work well. I could not get the "official" drivers from the manufacturer website to install (requires kernel module compilation and that fails).For Ubuntu or Mint users there is a version of the driver that is installable and works great - however it requires you to have two development files installed which are not installed by default. SO you have to already have the driver and those two files downloaded or backed up somewhere to get internet. Why are these not installed by default??? I have no idea, but it's definately not good.If anyone needs the info, these are the required files to be downloaded before install (I use Linux Mint 19.2):rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu8_all.deblibc6-dev_2.27-3ubuntu1_amd64.deblibc-dev-bin_2.27-3ubuntu1_amd64.debYou install the libc dev files first. If dkms build fails upon install of the rtl8812au driver, then open a terminal and go to the /usr/src/rtl8812au-4.3.8.12175.20140902+dfsg directory and do a "make install" manually. I tested it on default 4.15 and 5.0 kernels.On Windows 10 it is configured by default, but the performance is pathetic. After automatic install and a reboot, Windows Update pulls a new driver for the Alfa and that new one (in my case 7/19) work ok.Not what I expected, but once properly installed and configured it has some great performance :)

My main desktop computer died and all I had was an older desktop with no wireless built in. Running ethernet was not an option for me, so I purchased this item and just moved the hard drives over. Set up was fast and easy, and it connected to my router without issue. It worked well enough that I put off replacing the desktop and I still use it for the internet connection for it today. I mostly use a laptop now, but I still rely on this unit when I need to access my larger archive drives. The speeds stay consistent and it has never once dropped the connection like I have experienced with some other brands.
