No, modem/router is in a different room. I'm going to be running ethernet to a room the other end of the house. Also in that second room, I have a tablet that can only connect to WiFi. And the WiFi signal in the second room isn't strong enough.In the simplest terms, if your ethernet cable in that room is connected to the current wifi router, just install a wifi router/access point to the other end. It will allow wifi and ethernet access in that room as well.
An access point.But I'm wondering if there was something that I could put on the Ethernet in that room that could communicate to the tablet with WiFi.
