AX200 5Ghz works only with 20Mhz channel width

[RAi001]

My network adapter works only with 20Mhz channel width on 5Ghz. When the channel width is set to Auto, I am not able to connect to Internet and the pc is buggy.

I attached the logs of SSU.

Thanks in advance for your help.

Hello RAi001,

Performing wireless integrations is subject to country-specific legal regulations. Before installing or changing the Intel® Wireless Adapter, you must contact the system manufacturer to obtain approval, step-by-step instructions, and support. It is worth mentioning that the integration may or may not work due to the following reasons:

1. Hardware/software compatibility issues or dependencies.

2. Manufacturer limitations.

3. Driver limitations.

In this scenario, you can try these steps:

Clean Installation of Wireless Drivers

Step 1: Get the latest system-specific driver from your computer manufacturer support.

• Intel® Wireless Bluetooth® for Windows® 10 Version: 21.80.0
• Windows® 10 Wi-Fi Drivers for Intel® Wireless Adapters Version: 21.80.2

Step 2: Uninstall your Wi-Fi driver.

Windows* may have an inbox Wi-Fi driver for your wireless adapter. You can't uninstall an inbox driver (you won't see the "Delete the driver software for this device" option). Proceed to the next step if you start seeing the same version of the driver installed automatically after it’s uninstalled.

1. Go to Device Manager.
2. Expand the Network Adapters category.
3. Right-click your Intel Wireless Adapter/Bluetooth and choose to uninstall it.
4. Make sure to select the option to Delete the driver software for this device.
5. Restart your computer.

Step 3: Driver installation.

Locate the driver you downloaded back in Step 1. Run as administrator, and follow the wizard to completion.

If the issue persists, please let us know so that we can look into it.

It is worth mentioning that Intel® Wi-Fi 6 AX200 supports 2.4Ghz, 5Ghz (160Mhz), which could mean that the HOME&LIFE HUB is not properly identifying the adapter and the Wi-Fi configuration.

• Does the AP/router support 802.11ax?
• Could you please provide us with a specific model number for the HOME&LIFE HUB? We were not able to find additional product specifications with this information.
