Mobile Hotspot Not Working on Windows 11 25H2 (OS Build 26200.6901) - MediaTek MT7921 Adapter

FURKAN YILDIZ 15

Hello,

I am experiencing a persistent issue with the Mobile Hotspot feature on my HP Victus 16 (e-1005n) laptop immediately after updating to Windows 11, version 25H2 (OS Build 26200.6901).

System Details:

OS: Windows 11 Pro

Version: 25H2 (OS Build 26200.6901)

OS Build: 26200.6901 (Initially 26200, updated with KB5070773)

Wi-Fi Adapter: MediaTek MT7921 Wi-Fi 6 802.11ax PCIe Adapter

The Problem:

The "Mobile Hotspot" feature can be turned on in the Windows Settings. However, no device (phone, other laptop) can successfully connect to it. The devices see the network, attempt to connect, but fail every time. This functionality was working perfectly fine before the 25H2 (OS Build 26200.6901) update.

When I run netsh wlan show drivers in PowerShell, the output states:

"Hosted network supported : No"

Summary of Troubleshooting Steps Taken (All Failed):

I have tried every recommended solution but the problem persists. This appears to be a deep driver or OS-level bug introduced with 25H2 (OS Build 26200.6901).

1. Driver Management:

Roll Back Driver: The option was grayed out.

Manufacturer Driver: Uninstalled the device and installed the latest official driver from the HP support website (Version 3.5.0.33, dated Oct 2023). This did not fix it.

Latest 25H2 (OS Build 26200.6901)-Specific Driver: I manually downloaded and installed the absolute latest driver from the Microsoft Update Catalog (Version: 25.40.2.582, dated Aug 7, 2025, specifically listed for "Windows 11 Client, version 24H2 and later"). The driver installed successfully, but the hotspot still fails to connect.

2. Windows Updates:

I have installed all available Windows Updates, including the latest out-of-band update KB5070773, which brought my build to 26200.6901. This update did not resolve the issue.

3. Network Configuration and Services:

Hotspot Band: Changed the Mobile Hotspot network band in Settings from "Any available" to "2.4 GHz" and also tried "5 GHz". Neither worked.

Windows Services: Checked services.msc and confirmed that "Windows Mobile Hotspot Service" (icssvc) and "Internet Connection Sharing (ICS)" (SharedAccess) are set to "Automatic" and are "Running". I have also tried restarting them.

Network Reset: Performed a full "Network reset" from the Advanced network settings and restarted the PC. This did not fix the issue.

Power Management: In Device Manager, unchecked "Allow the computer to turn off this device to save power" for the MediaTek adapter.

Conclusion:

The issue is not a simple misconfiguration or an outdated driver. I am running the latest available OS build (26200.6901) and the latest 25H2 (OS Build 26200.6901)-compatible driver (25.40.2.582) for my hardware, and the feature remains broken.

This seems to be a significant bug in the Windows 11 25H2 (OS Build 26200.6901) networking stack or its interaction with the MediaTek MT7921 driver.

Is this a known issue, and is there any other potential fix or workaround available?

Thank you.

Hi FURKAN YILDIZ,
I'm sorry to hear that the above solution does not work with you yet.

I will provide some alternative solutions, please kindly follow the instructions bellow.

Check your applications

Some applications interact with system network such as VPN may lead to the issue, even they run in background or service, and VPN function is not turned on.

Click Start > View network connections
Enable Mobile Hotspot
Mind the Adapter has just created after you enable Mobile Hotspot (example: Local Area Connection 2*)
Mind the Adapter you're using to connect to internet > Properties > Sharing
Check Allow other network users to connect through this computer's Internet connection
Home networking connection: choose the created Mobile Hotspot adapter (example: Local Area Connection 2*)
OK to apply
Try connecting your mobile to the hotspot again
If problem persists, turn off Sharing option then re-enable Mobile Hotspot

Check IP conflict

By default, Hotspot will take 192.168.137.x IP range. Please ensure that other adapters do not have IP range conflict.

Static IP on your mobile

Navigate to Wi-Fi settings on your mobile, switch from DHCP to Manual and set static IP.

I hope that above suggestions can help you resolve the issue.

In case your issue persists or you have questions at any steps, please let me know.

Hi Lucus-V, Thank you for the detailed alternative solutions. I have now tried all of them, and I have gathered some critical findings.

Here is a summary of the results:

Check applications (Kaspersky):

I am using Kaspersky. I first completely disabled it, which had no effect. I then completely uninstalled Kaspersky and rebooted my system. The mobile hotspot issue still persists. This is not caused by my security software.

Sharing connections (Manual ICS):

  This is a key finding. My internet source is my __Ethernet__ adapter (wired connection). I followed your steps exactly:
  
        I enabled the Mobile Hotspot (which created its virtual adapter, "Wi-Fi" on `192.168.137.1`).
        
              I went to my __Ethernet__ adapter's __Properties > Sharing__ tab.
              
                    I checked "Allow other network users..." and selected the new hotspot virtual adapter ("Wi-Fi") from the dropdown menu.
                    
                       __Result:__ This failed. Devices still could not connect or get internet.
                       
                       __Check IP conflict (ipconfig):__
                       
                          I have confirmed there is __no IP conflict__. My internet source (Ethernet) is on a public IP (e.g., `95.183.x.x`), and my hotspot adapter is correctly on `192.168.137.1`. The ranges are not conflicting.
                          
                             I am attaching my full `ipconfig` output below for your review.
                             
                             __Static IP on your mobile (Adım 4):__
                             
                                This was the most revealing test. When I set a static IP on my phone (IP: `192.168.137.50`, Gateway: `192.168.137.1`):
                                
                                      My phone __did__ show "Connected" to the hotspot network.
                                      
                                            However, the Windows "Mobile Hotspot" settings page __still showed "Devices connected: 0"__.
                                            
                                                  My phone had __no internet access__.

Conclusion:

These tests confirm that the problem is not a simple misconfiguration. The core Internet Connection Sharing (ICS) service in OS Build 26200 appears to be broken.

It is failing in two ways:

The hotspot's DHCP server is failing to assign IPs automatically.

Even when a device is manually placed on the network (Static IP test), ICS is failing to route packets from my Ethernet adapter (internet-in) to the Wi-Fi hotspot adapter (internet-out).

This appears to be a deep OS-level bug. Is this a known issue, and can this be escalated to the engineering team?

Hi PUNITKUMAR NATVARLAL GAMI,
Please try my suggestions above.

If it does not work, please con tact Lenovo / Realtek for better compatible drivers.

Thank you for your understanding and sympathy.

Hi FURKAN YILDIZ,
Thank you for your information.

Please try further suggestions bellow.

Open Registry Editor

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
1. Navigate to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WlanSvc\Parameters\HostedNetworkSettings
2. On the right side, if you see a keyword HostedNetworkSettings, delete it
3. Test your Mobile Hotspot again (with both enable and disable Sharing Connection as my above post)
Scan you Windows
In case your Windows has corrupt files, please run these 2 commands on Command Prompt (Run as Administrator) to scan and fix
```
   sfc /scannow
   Dism /Online /Cleanup-Image /RestoreHealth
```
After that please reboot your computer then test the Hotspot again.

Hi FURKAN YILDIZ,
Welcome to Microsoft Q&A forum. I'm happy to help.

The driver of your Wi-Fi chipset may not be compatible with latest Windows 25H2. You may try to fix the issue with this command (Run as Administrator):

netsh wlan set hostednetwork mode=allow

If the problem still persists, please let me know with some screenshots of your Hotspot settings.

Thank you for your time.

RE: Mobile Hotspot Not Working on Windows 11 25H2 (OS Build 26200.6901) - MediaTek MT7921 Adapter

Hi Lucus-V,

Thank you for your reply and suggestion.

I have followed your instructions and ran the netsh wlan set hostednetwork mode=allow command as an administrator, then rebooted my computer.

Unfortunately, this did not solve the issue. The Mobile Hotspot still turns on, but no device can connect to it (they fail to obtain an IP address).

As you requested, I am providing detailed screenshots of my settings and system state after running your command.

Screenshot 1 (Command Output): This image shows two things:

The command netsh wlan set hostednetwork mode=allow executed successfully.

The output of netsh wlan show drivers, which (as I mentioned in my original post) confirms that the currently installed driver reports "Hosted network supported : No". This is likely why the set hostednetwork command has no effect.

Screenshots 2 & 3 & 4 (Mobile Hotspot Settings): These images show my Mobile Hotspot settings page. The feature is "On," but as you can see, "Devices connected: 0 of 8" because no device is able to complete the connection.

Screenshot 5 (Driver Version): This is the driver property page for my MediaTek MT7921 adapter. As noted in my original post, I am using the absolute latest driver available from the Microsoft Update Catalog (Version: 25.40.2.582, dated Aug 7, 2025), which is specifically for Windows 11 version 24H2/25H2.

Screenshot 6 (Device Manager): This shows my list of network adapters. As you can see, the MediaTek driver is installed and appears to be "healthy" (no error icons or yellow triangles).

Given that I am on the latest OS build (26200.6901), using the latest 25H2-compatible driver, and have already tried a network reset, this problem does not seem to be a simple configuration error.

This appears to be a compatibility bug between the Windows 11 25H2 networking stack and the MediaTek driver.

Are there any other diagnostic steps I can take, or is this a known issue being tracked by the engineering team?

Thank you for your time.
