Disable wireless when connected to Wired Network

Greetings,

Simple question:

Is it possible via a GPO/other way, to disable wireless when connected to a wired network?  Then when the end user pulls out the network cable it returns to wireless?

We have two many end users using the wireless connection even when they are connected via cable to the corporate network.  This is taking a lot of unnecessary bandwidth.

We wish that when user comes out of a meeting, and they re-dock their laptop, that it automatically changes to the wired connection.  Then when they undock, it goes to wireless.  

Thanks in advance

Declan

at first, you commonly no need to worry about extra bandwidth usage when wireless and wired links are both connected as all traffic will go through the default gateway over the wired connection with lowest metric value (higher bandwidth hence higher priority) in the routing table. the reason is normally a wired connection has better bandwidth. please see below the MSKB on how it works on Windows.

of course, when both wireless and wired links are connected, some standard local traffic such as broadcast and diagnosis services does apply to both connections. however, comparing to whole traffic over the LAN, the amount can be normally ignored.

lastly, if you really think it is necessary to automatically disable wireless anyway from Windows level, this third-party application may help you

Sorry for the late reply.  We work with Juniper and they have a program called Junos Pulse that will automatically change the connection state.
