Hello Jamie, If the AR2412 is the older version, then yes the first step is to go back to V1.61 firmware. Also, use a short, 3M, factory Cat6 patch cable to test. Use the D-Snake connector on both the GLD80 and the AR2412. Once you establish you can sync the AR to the GLD, then you can try a longer shielded Cat cable. I have used 150’ Ethercon and 150’ shielded cat6 with success. Hope this helps, Lee ---
