I've searched on Google, although maybe I'm not using the appropriate terminology or keywords to get the right answer, because I haven't really found any answers that I can understand. So here's the task:
I want to use a cantenna or some other directional type wifi antenna to receive the park-provided wifi signal as my ISP. BUT I want to use my own private, secure wifi network that I've already got configured. My wifi router has a USB port that I've got a backup drive plugged into. I don't want to connect my computer/ipad directly to the park wifi, I want to use my own secure network. What the heck sort of device do I need to accomplish this? It needs to be able to receive a wifi signal via. coaxial connector (hooked to the external antenna), and output this signal via. ethernet so I can plug it into my wifi router. OR, replace my wifi router with a single device that could accomplish this.
