ALFA AWUS036AXML 802.11axe WiFi 6E USB 3.0 Adapter AXE3000, Tri Band 6 GHz, Gigabit Speed up to 3Gbps, TAA Compliant

Works with Current Raspberry Pi OS (Bookworm) on a 3B+ and 4B. Also works with Arch on Intel. I had some trouble with Kali, but I'll bet the latest version with a more recent kernel works fine. Make sure you have a good power supply for your Pi.

I just purchased this adapter to take advantage of the capabilities associated with the 802.11ax standard, and despite the official stance that it should be "plug and play" on Ubuntu, I did run into an issue with getting it to work. The fix is pretty easy though. My system is running Ubuntu 22.04 with the latest kernel, but in order to get the driver to load properly I had to disable bluetooth by blacklisting it in my /etc/modprobe.d/blacklist.conf file. For good measure I also removed the two BT firmware files (BT_RAM_CODE*) in /lib/firmware/mediatek/. Once I did that it started working.

Despite repeated attempts over two days, this device was never fully functional on Debian/Ubuntu. No matter how many drivers I downloaded and installed via the mfr's website support pages (which shouldn't have been necessary because the drivers should be native to the kernel), Linux refused to recognize it. Tried on two different machines and different Debian distros without success.Some forums suggest that the device absolutely requires USB 3.1 to function, although this is not spelled out in the specs and I found it the USB port series made no difference.The box contained a card that urged dialing customer support for help, but the phone was never answered despite multiple attempts. Doesn't work and no customer support. I can't return because the Amazon window is closed, so I'm out $60+. Alfa is history for me.

I use this in combination with a GL.iNet GL-MT3000 travel router to rebroadcast a local wifi signal on my own SSID - this allows me to avoid having to log every device into the network, solves the incompatibility of Chromecasts with hotel captive portal setups, and have all of the connected clients tunnel through a VPN even if they don't directly connect to the VPN themselves. This plugs into the router's USB port, and connects to the local site AP, while all clients connect to the MT3000.This device is supported well in OpenWRT's master branch (and maybe the 23.x releases?)The only minor issue, and it's kind of a known quantity for Alfa's high-power long-range units, is that it's a power hog and will not work reliably with the MT3000 using that router's stock power supply which is undersized - you need to inject extra power into the system to have it be stable. But that's more of an issue with the MT3000 than this product.

It was pretty good picking up signals, but they were mostly unstable connections. Driver is buggy. Had to uninstall remove, then reinstall a couple of times (at the suggestions of tech support who responded pretty fast) because it would stop being recognized by my laptop. Honestly, some of that probably had to do with the distance and connection, but my older built in adapter worked much better. I returned.

I have nothing bad to say about this product. It was plug and play on my raspberry pi 5 and instantly had the fastest wifi in the house and i have 2 kids on summer break during a heatwave sucking all the wifi they see up. Excellent buy! I would buy it again and recommend it to everyone

Works fine, connects to my router running WPA3 Personal.Be aware that the Windows driver does NOT support monitor mode, so if you plan on Wiresharking, you'll need to be running Linux.

MT7922 chip has in kernel drivers in recent kernels. Worked in x86_64 arch Linux and a RaspiOS bullseye install on an Rpi3. Tested via hostapd to make an access point, and everything was just plug play, charge the config text file and bam DIY access point. For bonus stability, disable Bluetooth if you don't need it.Power is decent, made it about 25m through 3 walls from the house to the garage on 2.4ghz, about as good as my old R7000 router could do.Alfa stuff is not the cheapest out there, but it is well made.
