## USB WiFi adapter speed comparison test

Note: This is a test using a capability that all of the tested adapters have (WiFi 5).
This is a test using a capability that all of the tested adapters have (WiFi 5).
All adapters were tested from the same location connected to the same access point (AP).

Test setup:

```
WiFi 5
AC
5 GHz
Channel 116 DFS - clear air (no other APs on the channel)
80 MHz channel width
WiFi Router: ZyXEL NBG6817 (Wave 2) (running OpenWRT 22.03, iperf3 -s)
WPA3
Distance: about 7 meters (20 ft)
Obstacles: 2 walls
Client system: Desktop i7 running kernel 6.1 (Xubuntu 22.10, iperf3 -c 192.168.1.1)
Adapters tested in managed (client) mode
```

The adapters and results are sorted by their bitrate/ speed (fastest one at the top).

-----

```
WiFi Adapter: Comfast CF-951AX
Capability: Wifi 6E - AXE3000
Chipset: mt7921au
ID 0e8d:7961 MediaTek Inc. Wireless_Device
Note: Do not take the inclusion of this specific adapter in this test as a
recommendation. There are better adapters with this chipset. The mt7921au
chipset and the mt7921u driver are proving to be fast and stable.

Comments: I used adapters with many modern chipsets so as to show the relative
performance you can expect. Keep in mind that this is a speed test at short to
medium range, not a range test. The Alfa ACHM and ACH would run away from the
pack in a range test.
