Extending Wi Fi Across a Castle Grounds
So Friday I have a new internet provider setting up 12mb download service at the castle. It's satellite (Exede), but it's better than Hughes.net. Once I have a pipe worth sharing, I need to extend my wireless coverage. It's currently set up off a single router in the castle proper, and only covers a portion of that. I need to extend it throughout the castle, as well as out to and across the entire village complex - probably an area of 5 acres or so.
At home I extended my wireless range by simply adding a second wireless router, hardwired into the network, with the same SSID on different channels. At the castle I'm not going to be able to get a hardwired connection out to the village without trenching. Is it possible to extend my wireless range in a purely wireless manner? Can I setup a second wireless router while it's connected via Cat5, then disconnect it and move it to the edge of the current wireless range? Or once it's disconnected from the wired connection will it stop working as an extender? What other options do I have?
Thanks again to the GWJ Tech Horde!
