BrosTrend AX1800 Linux WiFi 6 USB Adapter (AX4L)
Fast, stable Wi-Fi 6 for Debian and Ubuntu family systems, with a driver that needs care.
The short version
- Ubuntu, Mint, Debian and Raspberry Pi OS users who want Wi-Fi 6 from a USB port
- Desktop PCs placed far from the router, where the antennas and cable help
- You run Arch, Fedora, Manjaro, Kali or another distro not on BrosTrend's list
- You want plug and play with no driver installation
- You need 6 GHz Wi-Fi 6E
What owners like
- Clear step up in speed and latency over Wi-Fi 5 adapters
- Stable connection with very low packet loss in a long hands-on test
- Driver script installs quickly, about a minute on a desktop PC and a few minutes on a Raspberry Pi 5
- External antennas help in rooms far from the router
Common complaints
- The 1800 Mbps rating is not reachable in real use
- Arch, Fedora, Manjaro, Kali, Pop!_OS and other distros are not supported by the official driver
- Kernel updates, or a built-in kernel driver loading in place of BrosTrend's, can cause dropouts or a dead adapter
- Some users had to switch to a different community driver to get it working
Based on BrosTrend's AX4L product page, the Amazon listing, a three page LinuxLinks hands-on review and two Linux Mint forum threads about BrosTrend driver problems (one on an AX1800 model, one on a different BrosTrend adapter with the same kind of driver conflict)..

First bought.
Drew's hands-on notes for this product are on the way. Long-term updates will be added to this timeline.
What it does
A dual band Wi-Fi 6 USB adapter with two external antennas, sold with a Linux driver installer for Debian and Ubuntu family systems and Raspberry Pi; the Amazon listing for this item is the AX4L long range model.
- One command install script that checks kernel headers, downloads the driver and builds it
- Works on x86 PCs and on Raspberry Pi 2 and newer
- Beamforming, MU-MIMO and OFDMA support
- Extension cable and cradle let the adapter sit away from the back of a PC
- Also works on Windows 11 and 10
A good pick for a Ubuntu, Mint, Debian or Raspberry Pi OS machine that needs faster, steadier Wi-Fi than a Wi-Fi 5 dongle. The trade-off is the driver: it relies on BrosTrend's install script on most supported systems, many popular distros are not supported, and forum threads show kernel updates and driver conflicts can break BrosTrend adapters.

Questions
Does the BrosTrend AX1800 work on Linux without installing a driver?
BrosTrend's setup has you install its driver first, with an internet connection, before plugging in the adapter. A commenter on the LinuxLinks review reports the in-kernel driver covers it on kernel 6.17 and newer.
Does it work on a Raspberry Pi?
Yes. BrosTrend lists Raspberry Pi 2 and newer running Raspberry Pi OS 8 to 13.
Does it work with Fedora or Arch?
Not with the official driver. BrosTrend lists Arch, Fedora Workstation, Manjaro, Kali and several others as not compatible.
Will it reach 1800 Mbps?
No. That is the combined rating of both bands. LinuxLinks measured around 200 Mbps in its worst case room, which it still found better than several laptops.
