You will need the following components:
Lightning to USB3 Camera Adapter - (must be the official Apple dongle, not a knockoff - and it must include a lightning power port)
USB Ethernet Adapter - (some knockoffs could work, but the official Apple adapter is the one we've been testing)
Standard Ethernet Cable - (length to fit your specific setup)
Order of operations is important, and it MUST be powered from an AC outlet, not via USB from a computer:
Connect ethernet cable to network
Plug the ethernet adapter into the camera dongle
Plug in the power (Lightning) connection into camera dongle
Turn off wifi on the iPad
Connect camera dongle to iPad
After 5-10 seconds, should have internet and network access
