I had a mesh network setup with 3 Deco M5 units. Recently I started experiencing network outage on the far end of the house.
So I decided to add more satellite units. I bought 2 Deco M9 plus units with the idea to make one of them the main Deco unit.
I was able to add the new M9 plus units on my existing network and everything was working fine.
But when I tried to make the M9 unit as the main deco using the "set main deco" function on app, M9 unit was unable to get internet.
Tried all options and idea from internet. Also called the Tplink hotline for support. Was told to switch off modem for 20 minutes and disconnect all cables, then try again. Still no luck.
Anyone got a clue on this.
