Some users experience connectivity issues when docking or undocking from a hard-wired to a wireless connection and vice-versa . This article describes how to correctly configure the wireless network adapter priority in Windows to prevent network communication loss.
Click the Start button.
Right Click Network and then left Click Properties.
From the Network and Sharing Center window click Change Adapter Settings.
On the Network Connections window, press the ALT key on your keyboard to bring up the menu bar.
Click the Advanced menu and then Advanced Settings.
In the Advanced Settings window you will see the Adapters and Bindings tab and under Connections you will see the order they are in. You can use the arrows to the side to move the Wireless Network Connection priority up for this example.
Traffic will go over the adapter with the highest priority first (when connected). The computer will still connect to all adapters, unless you have one disabled.
