It should be here in two days and will try that next. So I have ordered a different usb-to-ethernet adapter that is specific for android connection that shouldn't need drivers. I have determined that the usb-to-ethernet adapter that I have is meant only for PCs (windows and MAC) and requires drivers, which the Jetpak apparently can't accommodate.

I'm also posting this question so that others would have the information should they choose to go this route. I thought that there would be an easier solution. I was only able to find one other thread regarding similar issues, and that one suggested that you have to set your LAN router to a BRIDGE configuration, but in doing so with this router, I would also have to change the IPV4 settings on the router, which messes up the router. I know very little about cellular and android technology, and a moderate amount about PC technology.

Bottom line is I'm trying to keep some very old technology running while at the same time add new technology, and mixing cellular and LAN based. The basic issue is that this particular Jetpack (MIFI 7730L) is new, and there just isn't much information out there on how to connect a cellular modem it to a home-based LAN router and what settings or changes have to be made to the Linksys AC5400 router to do so (this router is also new and updated technology, it was expensive, and we have multiple devices, some that have to be hard-wire connected to the router, and others wireless. The decision for cellular internet vs poor land line internet with no other alternatives has already been made for various reasons, including slow dsl speed, poor dsl reliability, internet availability, cost, mobility, and others. Ann, Thank you for your kind information, but we have gotten a little off track.
