Description of Issue:

After installing the latest firmware update, all three Deco PX50 units developed critical issues:

1. Powerline Backhaul Failure

   • “Powerline” no longer appears as a backhaul option in the Deco app.

   • Units no longer connect through the powerline network — only Wi-Fi or Ethernet.

   • Mesh performance has degraded substantially.

2. Excessive Fan Noise

   • All units now run their fans at full speed continuously, even when idle.

   • The noise level is very high and wasn’t present before the update.

3. One Unit Unresponsive (Solid Light Green)

   • One satellite Deco stays on solid light green.

   • Factory reset does not work — LED blinks once and returns to green.

   • Device is undetectable in the Deco app and cannot be re-added.

Steps Tried:

• Rebooted all units, swapped power cables, and changed sockets.

• Held the reset button 10 s – 30 s — no effect on the green-light unit.

• Attempted re-adding each unit to mesh; powerline option never reappears.

• Connected directly by Ethernet; unresponsive unit not detected.

Expected Behavior:

• Powerline backhaul should function as before the update.

• Fans should remain quiet under normal operation.

• Reset should restore factory defaults with pulsing yellow LED.

Actual Behavior:

• Powerline connection missing and non-functional.

• Fans run at high speed constantly.

• One unit permanently stuck with solid light-green LED.

Request:

Please advise on next steps — firmware rollback, recovery procedure, or RMA.
If a recovery tool or earlier firmware is available, I’d like to test it before sending units for replacement.
