Hi Developers,
I am a newbie here, I am helping customers to set up their testbed to test Wi-Fi 6 with Intel AX210 card.
One of their requirements is to fix the 802.11 mode, for example, I would like to test 11ac or 11n with a Wi-Fi 6 AP on AX210, the OS I am using is Ubuntu22.04, is anyone know how to do that with command?
Also the same question for Channel/Bandwidth settings.
Please let me know if you have any question.
Thank you for the help~~~

Hi Zack
Welcome to the community! It's great to see you're helping customers with their Wi-Fi 6 setups. To fix the 802.11 mode and set the channel/bandwidth on an Intel AX210 card running on Ubuntu 22.04, you can use the iw command, which is a powerful tool for managing wireless devices.
Here's how you can set the 802.11 mode for testing:
- Check the current settings:
- iw dev wlan0 info
- Set the Wi-Fi mode (replace wlan0 with your actual Wi-Fi interface name):
- For 802.11ac:
- iw dev wlan0 set type managed
iw wlan0 set freq <frequency> HT40+
- iw dev wlan0 set type managed
- For 802.11n:
- iw dev wlan0 set type managed
iw wlan0 set freq <frequency> HT20
- iw dev wlan0 set type managed
- For 802.11ac:
Replace <frequency> with the frequency corresponding to the channel you want to use.
- For channel and bandwidth settings, you can specify the channel width alongside the frequency:
- 20 MHz bandwidth (HT20):
- iw wlan0 set freq <frequency> HT20
- 40 MHz bandwidth (HT40+ or HT40-);
iw wlan0 set freq <frequency> HT40+
or
iw wlan0 set freq <frequency> HT40-
- 80 MHz bandwidth (VHT80):
- iw wlan0 set freq <frequency> VHT80
- 20 MHz bandwidth (HT20):
Please keep in mind that you'll need to replace <frequency> with the specific frequency for the channel you're testing. Also, make sure that the channel and frequency are supported by the AX210 card and are legal in your region.
Remember to check the regulatory settings and ensure they match the requirements for the channels you're testing. You can view the current regulatory domain with:
> iw reg get
And set it with:
> sudo iw reg set <country_code>
Replace <country_code> with the appropriate ISO country code.
I hope this helps you set up the testbed for your customers.

Set the Wi-Fi mode:
- For 802.11ac:
- iw dev wlan0 set type managed
iw wlan0 set freq <frequency> HT40+
- iw dev wlan0 set type managed
