We have tried the Aukey PB-W2 (discontinued) and Aukey PB-W3. Just attach to the C3 ethernet port and turn on, no configuration is needed. Connect your laptop to the Aukey wireless network and you can do diagnostics from the ground instead of climbing in the machine cab.

TP-LINK TL-MR3040 is a portable Access Point I am currently using for doing this same thing with an MD4. It works really well and is also self powered.
