Hello. I have TP Link Deco S7. I have the same problem. The Deco device is connected to the main router by cable. If the main LTE router disconnects from the Internet and starts up again after a certain time, the DECO device disconnects, the indicator lights red and it no longer connects. I have to restart the whole system, which is impossible, since I am not always with this device. Please fix this problem

@David-TP 

 

yesterday I had make one small change to my network - I've connected the main-DECO to a switch instead directly to the router. then I've updated the FW on my router causing, surprise-surprise, an internet outage angel

 

Observation:

  • the main-DECO stayed white - no red-madness anymore yes
  • the main-DECO was still serving DHCP requests while the router was down no

 

Conclusions:

  • the red-madness is definitely triggered by ETH interface of main-DECO going down
  • the DHCP is still activated when the Internet connection is down 
    • Q: is this triggered by main-DECO disconnected from cloud? or is the main-DECO periodically checking for presence of foreign DHCP?
  • all my M4R v2.0 are on FW level 1.6.1 Build 20231227 Rel. 80438 and Android App on version 3.7.14 - but I can't turn Smart DHCP off as advised by @Alexandre as the option to do so is (still) missing
  • after changing the network topology, only devices which are periodically checking for internet availability were affected - e.g. mobile phones (they're trying to reconnect and get new IP)

 

Workaround:

  • so, my suggested workaround for red-madness is: use switch between router and main-DECO as this is triggered by ETH-down event

They now offer beta firmware 1.7.0, which they claim for sure will let you turn SmartDHCP on. You can get it from here: https://community.tp-link.com/en/home/forum/topic/651248

Update:

 

after installing beta FW 1.7.0 Build 20240307 Rel. 49485:

  • I can turn off the Smart DHCP
  • tested several disconnect scenarios - it seems like red-madness is gone yes
  • To be improved: I can't access the System Parametes menu in WebUI - just eternal spinning circle.........

 

anyway, I'll strongly suggest, that the main DECO should be not connected directly to main router, but to a switch in between to eliminate the ETH-down event which started all the troubles.

 

hereby I consider this issue as preliminary closed - looking forward to non-beta FW
