Deco M5 periodically constantly loose internet connection (AP mode, ethernet backhaul)
Deco M5 periodically constantly loose internet connection (AP mode, ethernet backhaul)
2021-03-15 16:23:23
Model: Deco M5
Hardware Version: V3
Firmware Version: 1.5.1 Build 20201022 Rel. 66804

- 3 Deco M5 kit

-  Deco M5 is working in AP mode

- All 3 units connected to Cisco SG110-16 switch

- Router: D-Link DSL-G256DG

- Static IP assingment for Deco M5

 

Deco constantly loose connection internet connection and then connection is restored again. 

When connection is lost, Deco M5 units led is red and naturally it is not accesible through Deco Android application.

Note that all the wired devices connected to the same switch continue working with Internet fine. So the problem is just in Deco WiFi domain.

Looks the IP address assignment is periodically deleted (see fragment of log below).

 

Reboot/Reset, Switch ON/OFF , etc. didn't solve the problem.

Please, help.

 

Thanks.

Re:Deco M5 periodically constantly loose internet connection (AP mode, ethernet backhaul)

@vis0 

Thank you for your feedback.

There is a new firmware 1.5.3 for Deco M5 and could you please try to update the firmware first:

https://www.tp-link.com/support/download/deco-m5/#Firmware

https://static.tp-link.com/2021/202102/20210219/Deco_M5_V1_V2_V3_210203.zip 

 

In case the issue is not fixed, could you please help me check the following information:

1. Is the network topology like this:

ISP---D-Link DSL-G256DG---Cisco SG110-16 switch---3*M5(all in AP mode connected to the switch directly);

2. When the connection dropped, all the Deco units would turn red and restored the connection several minutes later, right?

Thank you very much and wait for your reply.

@TP-Link 

Hello.

 

Strictly saying the network topology is a bit more complex:

 

 

ISP---D-Link DSL-G256DG---Cisco SG110-16 switch---M5  (main M5, AP mode connected to the switch directly)

                                                             |

                                                Cisco SG110-16 switch---2*M5 (all in AP mode connected to the switch directly)

 

 

I.e. I have two Cisco switches (for two floors) in my network.

 

All the rest is correct.

 

Thanks,

Vladimir.
