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
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!
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.
