Cannot connect amazon echo dot or echo after long time of working correctly
I have a deco m9 mesh network with 3 nodes... its been up a running for a couple of years... I had many amazon devices connected to it with little problem for all of that time. Recently. I've had 2 echo dot (3rd generation) and an echo (3rd generation) stop connecting. Now no matter what I do they will not connect back to the m9 mesh network.
I tried a guest network new name, changed settings etc. Nothing at all will work.
I do have two very old gen 2 echo, an echo show 5, an echo show 8, and 2 echo inputs still working totally fine. What gives? It's so so frustrating...
