Deco M9 Plus firmware update: connection and other issues
I have updated Deco firmware to version 1.5.5 from this official page: https://www.tp-link.com/us/support/download/deco-m9-plus/v2/#Firmware
After update, the second device began to lose contact with the main Deco. Everything was stable before the update.
Now on all Decos, except for the main one, red indicators are constantly on. After rebooting the main Deco, all other modules connect to it normally. Deco app shows strong signal. But after a few minutes, the red indicator on the additional modules lights up again and communication with the main deco is interrupted.
I visited this official page again looking for new updates or fixes. And I saw that update 1.5.5 disappeared from the official site.
Was it wrong and how to fix it? Are there any hot fixes or firmware updates for Deco M9 Plus planned?
