Deco x20, router and switch address problem
2023-04-25 17:45:14
Model: Deco X20   TL-SG108  
Hardware Version: V6
Firmware Version:

I have connection problem with next combo:

Sagemcom F-3890v3

TL-SG108

Deco X20 V1 (x2) 

 

I think that problems related IP-address and DNS settings.

 

Can somebody tell step by step how I set all settings? 

 

Sagemcom is bridge mode and Decos routed. 

Deco change Lan ip itself and then I have problems.

Hi, 

The network layout is supposed to be:

Internet---Sagemcom F-3890v3---main Deco X20---TL-SG108---2*Deco X20s(if you want to create Ethernet Backhaul among Deco X20s).

 

As for the LAN IP issue, most of the cases I have seen about IP auto-change are due to IP conflicts.

Is there a customized DNS server in the LAN network, like Pi-Hole?

It is also suggested to check the IPV4 settings and LAN IP/subnet on the Deco APP to see if there are any overlaps.

Thank you very much.

Best regards.

The network layout is: Internet---Sagemcom F-3890v3---main Deco X20---TL-SG108---1*Deco X20s

I don't have customized DNS server in the LAN network, like Pi-Hole. This would be help?

I have tried to check all IPV4 settings and LAN IP/subnet on the Deco APP. Can you tell some example how these settings need to be and what Sagemcom settings related to these?

Thank you very much!

Best regards, Jaakko
