I Cannot Uninstall WAN Miniport (IP)

Save

WAN Miniport (IP) is a simulated device that is not an actual piece of hardware that can be removed. This virtual device is used by device drives to connect to a network. Windows needs the WAN miniport (IP) to perform wireless networking, PPP0E and Remote Access Service. Microsoft recommends that the user does not uninstall this device. If the drivers for this device are corrupt, then Internet access may be blocked, Virtual Private Networking disabled and RAS unusable.

About

  • WAN Miniport (IP) is created when a VPN if formed when connecting to a network at a jobsite or when remote access is made through the computer. It is necessary when performing peer-to-peer communications through the computer. It appears when automatic updates are rendered to Windows. New network devices write WAN Miniport (IP) to the device management list.

Disabling

  • Disabling the WAN Miniport (IP) is the best option for this virtual device. Uninstalling makes it more difficult to repair if something goes wrong. Run “devmgmt.msc” under the Start menu, and look for Network Adapters. Click on the drop-down arrow, and highlight the WAN Miniport (IP). Right-click, and select “Disable.” If the result is the stopping of network access, then enable the device.

Uninstalling

  • Launch “devmgmt.msc,” and find the WAN Miniport (IP). Right-click the device, and chose “Uninstall” from the list. Confirm the removal, and reboot the computer. If the BIOS lists WAN Miniport (IP) as a necessary device, then the computer will detect it as new hardware and install the drivers when it starts. Search WinUpdate for any updated WAN Miniport drivers when the device re-installs.

Failed Uninstallation

  • When the WAN Miniport (IP) does not install properly, it is because the device is tagged in the registry as “not user removable.” This virtual device is listed as “Packet Scheduler Miniport” in the registry. Always backup the registry before making any changes. Changes to the registry may make the computer crash. Look for the registry key HKLM\SYSTEM\CurrentControlSet, and check the attributes for the entry. 0x20 is the attribute for “not user removable,” and clearing the entry should make the WAN Miniport (IP) removable in the device manager. If the attribute reads 0x00000029, change it to 0x00000009.
