Quick Note

Before trying the fixes, make sure:

  • Your Windows 11 is up to date. Updates often contain important bug fixes.
  • You have a stable internet connection (wired or wireless) during troubleshooting.
  • You have administrative rights on your computer to make system changes.
  • You have closed any applications that may be using mobile broadband services.

Step 1: Restart Your Computer

Sometimes, the simplest fix is to restart your PC. This refreshes system processes and can clear temporary glitches causing mbbservice-exe to malfunction.

  1. Click on the Start menu.
  2. Select Power and then click Restart.
  3. Wait for your computer to reboot and check if the error persists.

Restarting is important because many Windows services rely on fresh starts to work correctly, especially after updates or accidental conflicts.

Step 2: Run the Windows Troubleshooter for Network

Windows has built-in troubleshooters that automatically detect and fix common network-related errors, which might include issues with mbbservice-exe.

  1. Press Windows + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find the Network Adapter troubleshooter and click Run.
  4. Follow the on-screen instructions and apply any fixes suggested.

This step helps because the troubleshooter checks for driver issues, service problems, or configuration errors affecting mobile broadband services.

Step 3: Check and Restart the MBBService Service

The mbbservice-exe runs as a Windows service. If this service is stopped or disabled, it can cause errors. Restarting it manually may fix the problem.

  1. Press Windows + R to open the Run dialog.
  2. Type services.msc and hit Enter.
  3. In the Services window, scroll down and find Mobile Broadband Service or MbbService.
  4. Right-click on it and select Properties.
  5. Set the Startup type to Automatic if it is not already.
  6. Click Start if the service is stopped, then click OK.
  7. Close the Services window and see if the issue is resolved.

This step ensures the system service responsible for mobile broadband is active and set to run automatically every time you start Windows.

Step 4: Update or Reinstall Network Drivers

Outdated or corrupted network drivers can cause the mbbservice-exe to stop working. Updating or reinstalling these drivers can restore proper functionality.

  1. Right-click the Start button and select Device Manager.
  2. Expand the category Network adapters.
  3. Look for any device related to mobile broadband or cellular modems.
  4. Right-click the device and select Update driver.
  5. Choose Search automatically for updated driver software.
  6. If no update is found or the problem continues, right-click the device again and select Uninstall device.
  7. Restart your PC, and Windows will try to reinstall the driver automatically.

Drivers act as a communication bridge between your hardware and the operating system. Keeping them updated is crucial for smooth service operation.

Step 5: Perform System File Check (SFC) Scan

Corrupted system files can cause errors with essential services like mbbservice-exe. Running the System File Checker tool repairs these files.

  1. Press Windows + S and type cmd.
  2. Right-click on Command Prompt and choose Run as administrator.
  3. In the Command Prompt window, type the following command and hit Enter:
sfc /scannow

This scan will check your system files and automatically fix any corrupted files it finds. It may take some time, so be patient.

Step 6: Reset Network Settings

If previous steps don’t work, resetting your network settings can help by restoring all network components to their default state.

  1. Open Settings using Windows + I.
  2. Go to Network & internet.
  3. Scroll down and click Advanced network settings.
  4. Click Network reset.
  5. Press the Reset now button and confirm.
  6. Your PC will restart and reset all network adapters and settings.

This is useful when complex network misconfigurations cause service failures.

Alternative Methods and Advanced Options

If you are comfortable with advanced troubleshooting:

  • Check Event Viewer Logs: Open Event Viewer (eventvwr.msc) and look for any error messages related to mbbservice-exe under Windows Logs > System or Application.
  • Use DISM Tool: This tool repairs Windows image files. Run Command Prompt as admin and enter:
DISM /Online /Cleanup-Image /RestoreHealth

Follow this with the SFC scan for best results.
