Would like to use a GPO if possible to disable a wireless connection when a laptop is plugged into a LAN, then release the IP address when disconnected and re-enable the wireless connection. This needs to be done for security reasons. Can it be done with a GPO or will software have to be purchased? I've found this option, but would rather it be done by a GPO if possible. Thanks.

  • What kind of laptops does your company use? If it is Dell you may be in luck. Dell has an option in the bios that disables the WiFi when LAN Is detected and automatically re-enables it when LAN is disconnected. Check out this guide from Dell.

Err, what?

Its not possible to "release" the IP when it is unplugged - there is no way to have the ability when someone pulls the network cable out. Your best option is to have a very short IP4, presuming you are using IP4, lease time so the IP gets recycled quickly.

In regards to the mutually exclusivity re: LAN and Wifi, I suspect you need some software to apply that kind of security(?) feature. I know HP laptop used to do that at a hardware level, but that was a long time ago.

  • This was a project given to me by higher ups where I work. I currently work at a bank, so security with wireless is a huge concern. So even if an IP couldn't be released, there's still no GPO that would disable a wireless connection when it's plugged into a LAN, correct. Have you used the software that the link directed you too? Thx
    • I've never heard of a GPO that can disable the Wifi when connected to the LAN...

      Oh I stand corrected:

      And if your on Windows 7...

      Not a easy thing to implement, unless your on Windows 8 by the looks of it.
      • Thx for the reply. Does not look easy at all since we're not running Windows 8. They'll have to spend some money for software.
