The connection randomly drops out between one or several days
I think the problems started begone after the last update.
My setup, I have a cable modem in bridged mode, connected a 1GB/S Router (disabled wifi) and when the Deco's M4 (AP mode) are connected with utp cables of the best Backhaul. There are 40+ devices connected
The problem: After a few days (one to three times a week) the connection of all three the deco's to the router drop's, I can't connect the internal webgui or ping the devices from the LAN site. The Wifi is stili broadcasting but it is using a internal dhcp with 'No internet'. The lights on the Deco's are still white. The Deco App shows that the network is offline.
The only way to resolve the issue is by disconnection all three the device's from power. power on the main deco wait to the white light and then power on the other two.
I found these steps on the website.https://www.tp-link.com/nl/support/faq/2428/ but that didn't help. I have also did a full factory reset of all devices and make a new network profile. That also didn't work.
I have added the log of the main deco after the reboot of a crash of the system. There are a lot of daemon.err in it and errors about sync-server.
I hope there is a solution, i have leaner my kids to reset the Deco's but i think that is not the way. If extra information needed i can help you with if have some computer and network knowledge.
