I have cable internet and WiFi at my house. When I moved in I asked the provider tech what I needed to get WiFi to my workshop about 240 feet away. He said to get direct burial coax cable (I forget the rg#) and a WiFi router. I had a sub-contractor bury the proper cable and connect it to coax on the pole with a splinter. I acquired a WiFi router and attempted to connect only to be informed by my cable provider that they would have to charge me for second internet connection. That's a no go, considering that I don't need it that bad. My workshop/man-cave has a smart TV that's used only occasionally.
So, can I connect the house router to the coax going to the shop via a LAN - coax adapter, and then have functional WiFi out there?
