My Network adapter for some reason is called "Ethernet TALKTALK752AB3_EXT". EXT is the name I gave to a WiFi extender many years ago that I am about to upgrade and have now disconnected. I have no idea how _EXT has ended up on my cable connection but I would like to rename it to avoid any confusion with the new WiFi extender I am about to install. When I go to Change Adapter Settings and Rename I only get the option to change the Ethernet part of the name. Can anyone tell me how to get rid of the _EXT on the ethernet connection?
