Review: Blazing Fast! Excellent Range! But not for everyone. - I run this WiFi adapter with Linux Mint 18, and it's excellent. If you buy this for Linux, be sure to install the drivers. I'm using the drivers from zebulon2/rtl8814au on GitHub. I suspect some Linux users gave negative reviews because they had driver issues. The drivers are easy enough to install for most Linux users, but if the terminal scares you, I recommend you take a look at that GitHub repo before you buy this. With that out of the way, here's my review: The range is excellent. This adapter picks up WiFi networks I've never seen before and with surprisingly strong signals. The range is especially good when I stick the adapter to my window with the included suction cup. But I get 100% signal strength connecting to my home's WiFi even when the adapter is clamped above my monitor. The adapter is fast! It's faster than my access point. I tested the speed with iperf3. The other computer was connected via Ethernet. I measured 250 Mbps, which is the best my access point can do. I saw someone else measure 940+ Mbps. It's not perfect, however. The specs aren't detailed enough; they don't say whether this adapter supports MIMO or MU-MIMO. It's sorta big and bulky, though its size might be needed to achieve its excellent speed and range. Also, if you're a Linux user, the driver's likely aren't included in your distro. The drivers are easy to install, and they work well, but the quick-start instructions don't tell you that you need to go to GitHub to get them. Also, if you're a Linux user, you need to know your way around the terminal (a little bit) to install the drivers. Beyond that, the included quick-start guide is terrible. It explains how to install the drivers on Windows XP. I suspect most people are buying this to use with either Linux or Windows 10. It's a bit eyebrow-raising that their quick-start directions are so out of touch. Also, it uses blue LEDs. I don't like blue LEDs, because they can interfere with sleep. This adapter isn't for everyone. But this is a good pick if 1) you're a computer professional or power user. Or 2) you need its range or speed, and you don't mind its size. Or 3) You're a Linux user looking for something high-quality, and you don't mind using the terminal a little to install the drivers. If you're the right kind of customer, then you're gonna like this WiFi adapter.
Review: An older high performance WIFI 5 802.11ac device thats worth it for most people still. - A good adapter with the realtrk 8814au chipset that is getting a little long in the tooth specs wise. It has good reception and good range and speeds. It has three spatial streams, 3x3 mimo, with the fourth antenna for increasing reception. Up to 1300mbps on 80mhz wide 5ghz channels and up to 600mbps on the 2.4ghz channel with 40mhz channels and 288mbps for 20mhz wide channels. Most routers are greenfield enabled so you'll only ever see 288mbps at 2.4ghz unless you force your router to 40mhz wide only or live somewhere desolate. At 2.4ghz it doesn't support mcs 9 when on one or two spatial streams on 20mhz 2.4ghz channels so you'll see 86mbps/173mbps. The RP-SMA connectors allow you to connect external antennas. I use a pair of the Alfa m26e directional antennas on both my Alfa AC1900 adapters for more signal strength and a better signal to noise ratio which yields higher connection speeds. The present version doesn't include a drivers CD but since windows 10/11 support it natively thats not an issue. I would recommend getting a longer 9 foot cord for it so that it can be positioned better. It will work on a 2.5 watt usb 2.0 port and even standard micro usb cord but you'll get slower speeds and it will run at reduced transmit power. I bought a Micro B USB 3.0 to USB-C cord for use with it and its been running flawlessly for me. I do wish the seller sold an elevated cradle stand for it that enables it to stand upright for more optimal antenna positioning and reception. The included clip and suction cup leave much to be desired. The antenna gain is 4dbm/5dbm for 2.4ghz/5ghz. If your adapter turns off or gives sub par performance I'd recommend going into your windows settings and control panel and disabling power saving features for USB and wifi. Having MU-MIMO enabled on your router will decrease its indicated speed to 433mbps but it should ramp to 1300mbps when doing heavy downloads or file transfers. Your actual connection speeds and throughput will vary depending on signal strength and SNR, the farther you're away from your router and more neighbors/interference you have the lower the speeds however its noticeably better than the majority of integrated wireless adapters. I wish Alfa would release a 4x4 mimo wifi 6e or 7 version of this venerable workhorse of an adapter.

## Questions & Answers

**Q: Does this work well with Kali Linux  the latest version and does it support packet injection as well as wireless mon ?**
A: Would anyone say the dual band is better than this adapter for Kali? Even with the dual band, you have to install realtek-rtl88xxau-dkms ... is this any different? I keep reading that it does work ... it doesn't work ... it does work ... it doesn't ... So, I am confused?

**Q: does this product work good for boondocking?**
A: Although the range is exceptional, it really comes down to how you plan on using it. If you're talking going out in the middle of nowhere, no. I know a guy that lives out of his van (by choice, not circumstance). I set him up with an older card and a laptop and he's able to grab wifi, but he mostly parks in the city.

**Q: Is a original alfa mac address start with 00:c0:ca or copy ?**
A: Original.

**Q: Does this work with alfa network 3.0 out of 5 stars  1reviews alfa tube-uac2 802.11ac dual band 2.4/5 ghz long range usb adapter 9 dbi omni ant. ?**
A: Yes

### ⭐⭐⭐⭐ Very good range but the drivers might not work or only work partially with different Linux distros.
*by N***S on December 17, 2025*

Very good range. Linux driver install can be challenging with different Linux distros. I don't like the cord connector. The cord is probably about a foot shorter than it needs to be and has a strange proprietary looking connection.
