I just replaced my cantenna (LTE Installed) service with a Jetpack. The Cantenna was an antenna connected by coax to a wireless router, and all the home devices connected to that router. I need to keep a separate home network for file sharing and printing but I don't want the Jetpack on all the time. I turn it off when I can to prevent any devices from inadvertently downloading updates etc. I don't see how to connect to both networks at once. What's the simplest way to do this? Is there an ethernet adapter for the Jetpack to connect directly to the old router? Do I have to set up bridging? Or is there some easier solution?
