How to permanently disable 6GHz / Wi-Fi 6E band on AX210 for product certification (on NVIDIA Jetson

[Gakobe]

Hello Intel Support Team,

We are developing a commercial product based on the NVIDIA Jetson AGX Orin platform, which is running a Linux system with kernel version 5.15 (aarch64). We are using the Intel Wi-Fi 6E AX210 module (M.2) for wireless connectivity.

For our global product certification process, we have a strict requirement to completely and reliably disable the 6GHz band. The device must only operate as a dual-band (2.4GHz / 5GHz) client, and the 6GHz capability should not be detectable or user-configurable.

Any help or guidance you can provide would be greatly appreciated.

Thank you.

Hello Gakobe,

Please be advised that the Intel AX210 is client-STA device and our Intel wireless adapter is only a receiver. With that in mind, you may disable the 6ghz the bandwidth on the computer by following the steps below:

• Open Device Manager:
  • Right-click the Start button (Windows icon) on your taskbar.
  • Select Device Manager from the menu. 
• Locate your wireless adapter:
  • In the Device Manager window, expand the Network adapters category. 
  • Find your Intel Wi-Fi or other wireless network adapter in the list and double-click it. 
• Access advanced settings:
  • In the adapter's Properties window, click on the Advanced tab. 
• Disable the 6GHz band:
  • Look for an option such as "Ultra High Band (6GHz)" or "Wireless Mode" in the "Property" box. 
  • If using "Ultra High Band (6GHz)", select Disabled from the "Value" dropdown menu. 
  • If using "Wireless Mode", you may need to select a 5GHz or 2.4GHz option from the dropdown list. 

1. Confirm the change:

• Click OK to save your changes. 

If you would like to disable the 6GHz bandwidth, it is advisable to change it on the AP setting and disable the 6GHz bandwidth.

Feel free to reach out if you need any more help.

Hello @JeanetteC_Intel 

Sorry for the late reply, because I experienced a typhoon yesterday...

My system is Linux, your reply seemed to be tailored for Windows. Could you kindly provide the same way on Linux?

Thanks a lot for your help!

Hello Gakobe,

Kindly check the following methods below:

Method 1: Router Configuration (Recommended) 

1. Access your router's settings: Open a web browser and enter your router's IP address (usually found on a sticker on the device) to log in to its administration page.
2. Locate Wi-Fi settings: Find the advanced or wireless settings section.
3. Disable the 6 GHz band: Look for an option to disable or uncheck the 6 GHz band or 6E support and save your changes.

Method 2: Using nm-connection-editor (If Router Configuration is Not Possible)

This method aims to disconnect from the 6 GHz band rather than disable it entirely. 

1. Open nm-connection-editor: Launch this tool to manage your network connections.
2. Select your connection: Choose your existing Wi-Fi connection to your network.
3. Edit the connection: Look for a way to set the desired band instead of "Automatic" (e.g., "2.4 GHz only" or "5 GHz only").
4. Apply changes and reconnect: Apply the changes and reconnect to the network. You may see a new connection created with a similar name.

Method 3: Check Your Driver and Kernel (Advanced)

Some Linux kernel versions, especially for certain Wi-Fi cards like the Intel AX210, may have 6 GHz disabled by default. 

1. Check iw list: Use the command iw list to see what bands your wireless device supports. 
2. Inspect iw reg get: Run iw reg get to check the regulatory domain and see if 6 GHz is disabled there. 
3. Update your system: Ensure your kernel and drivers are up-to-date, as newer versions might have specific support or limitations for 6 GHz bands. 

With that in mind, since we are recommending using the method 1, it would be best to contact the AP's support for assistance.

I'll proceed in closing this thread now. For future assistance, please create a new post as this thread will no longer be active.

Sincerely,

JeanetteC.
