I had thought that the Apple iPad was only wireless but that is apparently not so.
You can use the iPad connected by the router by a wire (CAT5 cable is technical term) and you can turn the wireless function off in both the router and the iPad.
Wow, now I can authorize the use of wired iPads by my grand kids. And I can now use an iPad with them.
See this facebook group for details.
