BrosTrend AX1800 USB WiFi 6 Adapter (AX4)
A practical WiFi 6 upgrade for Windows desktops, held back by Windows only support and occasional driver fuss.
The short version
- Windows desktop owners without built in WiFi or with an old WiFi card
- PCs placed far from the router where antenna placement matters
- You run Linux or macOS
- You want something small that stays plugged into a laptop on the go
- Your PC has no USB 3.0 port to get full speed
What owners like
- Straightforward setup on Windows 10 and 11
- Good 5GHz throughput for streaming, gaming and video calls
- Better range and signal stability than small nano adapters, helped by the antennas and extension cable
- Solid feeling build
Common complaints
- Occasional driver problems that need a manual reinstall or update
- No Linux or macOS support on this model
- Bulky on a desk, and the cable can be awkward to manage
- Real speeds depend heavily on the router and signal; the AX1800 figure is a combined theoretical rating

What it does
A dual band WiFi 6 USB adapter with two external antennas and a USB 3.0 desk cradle, made for Windows 11 and 10 PCs.
- Two adjustable high gain antennas aimed at better reception through walls and floors
- Cradle and 3.3 ft extension cable let you move the adapter away from the PC case for a clearer signal
- Driver is stored on the adapter itself, so setup does not need a disc
- Supports WPA3 encryption on newer routers
- Works with WiFi 6, 5 and 4 routers
A sensible upgrade for a Windows desktop or laptop with weak or outdated built in WiFi, especially where the PC sits far from the router. The trade-offs are that it is Windows only, it is a desk unit rather than a pocket dongle, and some owners report having to reinstall or update the driver now and then.

Questions
Does the BrosTrend AX1800 work with Linux?
Not this AX4 model. BrosTrend sells a separate AX4L version with Linux driver support.
Does it work on a Mac?
No. BrosTrend lists it for Windows 11 and 10 only.
Will I get 1800 Mbps?
No. 1800 is the combined rating of both bands. Real speed depends on your router, internet plan and signal.
Do I need a driver disc?
No. The driver is preloaded on the adapter, and BrosTrend also offers it as a download.
Which USB port should I use?
BrosTrend recommends a USB 3.0 port, and on desktops a rear port rather than a front panel port.
