The first time you resume from hibernation after installing a new network device, you receive:
You may need to run the Home Networking Wizard to continue sharing your Internet Connection. Click here to run the Home Networking Wizard.
Windows has detected the installation of a new networking device. If you want to set up a network, click here to run the Network Setup Wizard.
This message only appears once. You may press Cancel to resume normal operation of your computer.
This feature is probably designed to confuse you, as you may have installed and been using this device for months.
