Intel Killer BE1750s (BE201) doesn't detect 6 GHz wireless (repost)

APersonWithAProblem · ‎10-21-2025

Hi everyone,

More than a month ago, I opened a thread about the issue mentioned in the title. Despite following all the instructions provided by Intel support, the problem still persists — my wireless card does not detect the 6 GHz band.

I decided to reopen the thread because I want to understand why my card is having this issue.
Here’s the original post:

https://community.intel.com/t5/Wireless/Intel-Killer-BE1750s-BE201-doesn-t-detect-6-GHz-wireless/m-p/1714685#M61360

Device model: MSI Prestige 16 AI+ Evo B2VMG;

Nothing locked at BIOS level, every component is original.

What I've tried:

Ubuntu live → doesn't detect 6 GHz netowork
Enable all 6 GHz-related setting in advanced setting → doesn't work
Driver 23.70.2 from Intel → doesn't work
Driver 23.80.1.3 from OEM → doesn't work
Driver 23.160.0 from Intel → doesn't work
Clear Windows install → doesn't work
Force to select the unselectable 6 GHz band in "Mobile hotspot" in Windows with a powershell script → Windows says that it can't generate the mobile hotspot

About the 6 GHz access point tested:
I can connect to it with my other laptop that has the MediaTek MT7902 wireless adapter.

About my location:

The band legally regulated is 5925/5945-6425 MHz.

Hello APersonWithAProblem,

Thank you for posting in Intel community Forum.

For me to better understand and diagnose the issue further, let me ask you to provide detailed responses to the following questions. This information will help me isolate the problem and determine the most appropriate course of action moving forward.

Have you tried different access point or router with 6 GHz?
Have you tried contacting MSI if the laptop is capable of supporting 6 GHz?
If yes, can share the response of the MSI support?

If you have questions, please let us know. Thank you.

Best regards,

Michael L.

1. No, I didn't tried other 6 GHz access points, but I tried to run Fedora 42 live on my laptop: also Fedora doesn't show the 6 GHz.

2. Yes

3. I can't share the full conversation due to privacy policy, but I can share you the part where they confirm that my laptop is capable:

Hello xxxxxxx xxxxxxx,

Thank you for your reply and for your patience. We've conducted an internal review of the issue you reported.

Based on our findings, we can confirm that the wireless adapter in your MS-15A3 laptop is fully capable of connecting to and using 6 GHz Wi-Fi networks.

To rule out any software or system-level restrictions that might be causing this issue, we kindly ask you to perform a factory reset. This will restore the laptop to its original operating system state. You can find the detailed steps in the following FAQ:

APersonWithAProblem · ‎10-22-2025

UPDATE: thanks to a user on Stack Overflow, I tested this Powershell script:

[Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime] | Out-Null

# Define functions. Not important to this question
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
Function Await($WinRtTask, $ResultType) {
    $asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
    $netTask = $asTask.Invoke($null, @($WinRtTask))
    $netTask.Wait(-1) | Out-Null
    $netTask.Result
}
Function AwaitAction($WinRtAction) {
    $asTask = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and !$_.IsGenericMethod })[0]
    $netTask = $asTask.Invoke($null, @($WinRtAction))
    $netTask.Wait(-1) | Out-Null
}

# Create tethering manager
$connectionProfile = [Windows.Networking.Connectivity.NetworkInformation,Windows.Networking.Connectivity,ContentType=WindowsRuntime]::GetInternetConnectionProfile()
$tetheringManager = [Windows.Networking.NetworkOperators.NetworkOperatorTetheringManager,Windows.Networking.NetworkOperators,ContentType=WindowsRuntime]::CreateFromConnectionProfile($connectionProfile)

# Create configuration
$configuration = new-object Windows.Networking.NetworkOperators.NetworkOperatorTetheringAccessPointConfiguration
$configuration.Ssid = "Hotspot"
$configuration.Passphrase = "Psswrd1234"
$configuration.Band = 3

# Check whether Mobile Hotspot is enabled
$tetheringManager.TetheringOperationalState

# Set Hotspot configuration
AwaitAction ($tetheringManager.ConfigureAccessPointAsync($configuration))

# Start Mobile Hotspot
Await ($tetheringManager.StartTetheringAsync()) ([Windows.Networking.NetworkOperators.NetworkOperatorTetheringOperationResult])

As a result, I got this:

Off

AdditionalErrorMessage           Status
----------------------           ------
                       RadioRestriction

So, as suspected in my original thread, there is an embedded restriction on the BE201 adapter.

Mike_Intel · ‎10-23-2025

Hello APersonWithAProblem,

Thank you for the quick reply.

Before we proceed, I want to kindly set the expectation that your system is an OEM model from a third-party manufacturer. Because it includes components from other vendors, our support capabilities are somewhat limited.

If the recommendations we provide do not resolve the issue, the best next step would be to contact the system manufacturer directly for further assistance. They will have the most comprehensive knowledge of the specific configuration and components in your system.

Based on your reply, let me ask some information. Have you tried to factory reset as instructed by MSI support? If yes, how was it? If no, can you share why you did not perform the hard reset?

If you have questions, please let us know. Thank you.

Best regards,

Michael L.

If you pay attention to what I said in the first post, you will know that I performed a fresh installation of Windows (factory reset via MSI utility).

The manufacturer told me that the "RadioRestriction" is triggered due to Dynamic Regulatory Solution (DRS).

Mike_Intel · ‎10-27-2025

Hello APersonWithAProblem,

Thank you for the confirmation.

I will do further research on this matter and post the response on this thread once it is available.

If you have questions, please let us know. Thank you.
