Open Control Panel Click Hardware and Sound Click Device Manager In Network Adapters, find the LAN card you want to reset. This is often something like:

  • Realtek PCIe GBE Family Controller
  • Broadcom NetXtreme 57xx Gigabit Controller
  • Intel PRO/1000MT Network Adapter

Once you have identified the adapter,

  • Right click on the adapter and click Uninstall
  • You will be warned that this will remove the device from the system - ensure that 'Delete the driver software' is not ticked if this is shown

    Note: Clicking OK will disconnect your remote access session if you are connected!

  • Click OK
  • The icon will disappear, and the network adapter will be disabled
  • At the top of the device manager list, the PC name is displayed
  • Right click this PC name and select Scan for hardware changes
  • The network card should reappear in Network Adapters
  • The network card will be reset to default settings, so you may need to reconfigure IP addresses, reconnect to a wireless network etc.
