Accepted WAN/LAN auto-sensing
Background:
There is a typical network topology：
Some users might notice that, once the internet service fails, they are no longer able to access the NAS server from the local network.
The cause of this Phenomenon:
When internet service went down and the cable modem failed to provide an IP address for Main Deco, both Ethernet ports on the main Deco would work as WAN ports to detect internet connection. NAS would no longer obtain an IP address from Deco.
Why do we use WAN/LAN auto-sensing on Deco?
For the Deco Mesh system, normally, it would have more than 2 units, and each unit has at least 2 Ethernet ports; It would be time-consuming and confusing to find out which port should be connected to the ISP modem. And supposing that the WAN port is fixed, once this port is broken, the whole Mesh kit would be useless.
Recommended Solutions:
- Given that the issue arises only when the ISP modem fails to assign an IP address for the main Deco, once the cable modem recovers, the problem should be resolved. It is suggested to contact the ISP to restore the modem connection as a priority.
- The current workaround would be connecting the wired servers to the satellite Deco units instead of the main one.
- And we have also implemented enhancements on certain models, ensuring that the WAN port remains constant as long as the physical Ethernet connection between the modem and main Deco is unchanged, even when there is no internet service from the modem. Moreover, it is also planned to support manually fixing a specific Ethernet port as the WAN post on the Deco APP later.
The following models already support fixing the WAN port:
| Deco X80-5G Deco X50-5G Deco X20-4G Deco X50/X55_V1/V1.2 Deco X20/X60_V4 Deco X60_V3/3.2/V4.2 |

Hi,
That's interesting, as when my internet went down yesterday, so did the LAN. I will check what version I am on, as I might just not be up to date.
Thanks

Hi, the latest 1.7.1 firmware for Deco M5 has improved the WAN-LAN auto-sensing feature. If the physical connection between the modem and the main Deco has not been disconnected, the original WAN port has remained.
Best regards.

@David-TP Is the an ETA on this feature? It's been two months since it was said to be coming.
Like many I have a lot of devices such as my cameras, doorbell and loghts that don't require internet, instead working locally through Home Assistant. This is to reduce my dependency on the internet and cloud.
So to lose my local network when my internet goes down is counter to what I am trying to achieve.
I'm running 3x Deco M5, with the main one connected to the modem and a network switch. My house is then running cat 5 to the other rooms.
I'm about ready to ditch Deco and TP-Link altogether as this has been a bit of an issue lately with with several external infrastructure issue with my internet.

@MarkRound you could also do what i've done and returned the product, in UK the device has to be fit for the purpose it was purchased for and in its current state it is not. I mentioned this to Amazon that I believe TP-Link have had adequate time to resolve seeing this has been ongoing for 2 years and that normal network security/configuration is behind a paywall on top of the fee of the product then it is not actually fit for the purpose of being a router and requested a full refund.
This might make TP-Link listen but if they do when will the resolve...

Ok, so I've given up waiting - I've email the UK MD for TP-Link in the faint hope that generates some interest and action. I have refereed to this thread showing the level of dissatisfaction that this stupid design decision has caused - and to show how much distain the lack of response/action is generating for TP-Link customers (and ex-customers).
anyone interested in doing the same - I found him through LinkedIn - and have had as much response that route as through this forum.
