Got a pair of MA2500D and one of the unit's 'SEC' light indicator does not light up. What does 'SEC' stands for?
I've tried to establish a link between the 2 units with a coax cable directly connected to both devices but the 'MOCA' light indicator does not light up and I couldn't get an internet connection.
Sorry to hear this.
The SEC light is the indicaitor for MoCA secutrity status. By defualt the security funciton is disabled. So the SEC light should be OFF.
If SEC light of one adapter is ON, another one is OFF. They can't link up.
For the SEC light ON adapter, after power up, please press the reset button more than 5 seconds. This will clear the security configuraiton. Then please connect them direclty with a short coaxial cable. and check the MoCA link again.
If you still has Link issue, please let us know.
