Purchased a TRB140 back in January to serve as a fail-over connection.
After 5-10 minutes, the ethernet interface on the TRB140 just shuts off completely.
The LEDs on the RJ45 connection blink each three seconds; green twice, then yellow (dim) three times, then the loop starts over.
I have updated using the Legacy firmware and then updated again with the latest firmware.
Device was also dropping the ethernet interface with the 1.06 firmware.
