Hello,

I’ve recently installed new TP-Link equipment and I am having issues with an EAP773. The device keeps going through adoption → re-adoption cycles in the controller and constantly shows “Heartbeat Missed” messages.

My setup:

1. ER707M2 – dual WAN load balancing (2× 1Gb connections).

2. SG3428X – L2+ switch.

3. EAP773 – connected via SFP+.

Network path:

• The EAP773 is connected to the SFP+ port on the SG3428X.

• From there, the connection passes through a Mokerlink unmanaged 2.5Gb switch (with SFP+ uplink).

• The Mokerlink links to one of the 2.5Gb WAN/LAN ports on the ER707M2.

• ISP1 is connected to ER707M2 LAN3, ISP2 to the other 2.5Gb WAN/LAN port.

Problem:

• The EAP773 shows as “Adopting” then “Connected,” then drops again with Missed Heartbeat and repeats the cycle.

• I have not made significant configuration changes – only created a single SSID for testing stability.

• Other devices on the same path are stable, so the issue seems to be specific to the EAP773.

Questions:

• Could the intermediate unmanaged 2.5Gb Mokerlink switch (with SFP+) be causing instability?

• Is there a recommended connection path for the EAP773 to avoid heartbeat issues?

• Any firmware or configuration adjustments I should try?

Thank you for any guidance!
