@TP-Link My satelite Deco is having this problem. I tried to reset. No use. It is green for 10 seconds and Red pulsating for next 60 seconds. Cycle repeats like this throughout the day. What is the solution

  Greetings

My satelite Deco shows as PORTS NOT FORWARDED . Is it the reason for not being connected to main Deco. If so, how to correct it

  @David-TP Greetings

I notice this in the Firewalla i added

  @TP-Link I have a similar issue wherein a sattelite Deco dropped off and I am unable to reconnect as it flashes yellow then turns to red - I have changed it to the main Deco position and still not change

Wish I had never spent $230 for these stupid W7200 units.  I founght for months to get all my Google speakers to work with them.  Finally found a workaround but it was a mess.  Then a few months later my Ooma wouldn't connect anymore, even though every other device was still connected.  So I tried powering it, the base W7200, and the modem off and back on, and now I get the red light.  Finally did a reset on both W7200 units and did a new setup, and it shows internet working for maybe 30 seconds then goes to red light again.  Tried using the 2nd unit as the main after a reset and same result.  Tried 5 more times and same result.  (Comcast internet thru an M8600 modem.)

After hours of screwing with it, I finally gave up and pulled out the trusty old AC1750 those replaced.  It's always worked well but just doesn't have the range to reach the far end of the house well (Chromecasts seem to need a strong signal).  Spend the rest of the day relocating the modem and old router to a more central spot in the house, and then re-configuring all the plugs and cameras and thermostat etc etc etc.

What a waste of $230.

Switched the Ethernet cable from port 1 to port 3 and the issue was fixed instantly. Unfortunately did not figure this out until I spent over an hour talking to live chat. It ended up being my ISP who figured out the resolution even though it was a Deco issue.
