PSActiveNetworkSwitcher

https://github.com/aglasson/PSActiveNetworkSwitcher

Powershell Module to automate the switching of network connection states by having certain adapters disabled when other adapters are connected.
Can be used in automation or deployed to devices running Windows 8 or later. This module will not work Windows 7 or Earlier (regardless of PS version) due to Get-NetAdapter limitations.
Facilitating cleaner network switching when roaming between Ethernet and WiFi, on and off corporate networks.

Features

• Enable/disable wireless & other ethernet based on ethernet adapter state
• Allow or deny multiple ethernet adapter being enabled/connected at once
• Safe handling with Airplane mode turned on - Take no switching action
• Self deploy script runner and scheduled tasks to monitor event log for network changes and re-run the switcher

Logic

Order of priority in which if one is in the 'Up' state the others can not be. When Ethernet connected, wireless is disabled due to wireless being a "connect when possible" medium. Ethernet not disabled when wireless connected so connecting a network cable will trigger the task and switch WiFi off.

1. Ethernet
2. Wireless LAN (WiFi)
3. Wireless WAN (Mobile Broadband/Cellular) Note: If Airplane Mode is enable no action is taken.
