Connect a wire only device to a wireless only network

Need to work from home?  Maybe you need to use a wired only VOIP hardset but have no access, or reasonable access to run a wire to the router?

Here's a possible option for you using Windows 10 Internet Connection Sharing to connect a wired device(s) via an unused Ethernet port.

(Too Long Didn't Read)You can connect to the WiFi using your windows 10 machine, select internet connection sharing, share it to the Ethernet port and use that to plug in your phone, or devices.  Remeber that you will need a way to power your IP phone.
