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 cable modem failed to provide 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 failed to assign IP address for the main Deco, once the cable modem recovered, 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 WAN post on the Deco APP later. (Some models already support this feature, such as Deco X80-5G/Deco X20-4G)

@Sus_Deco it's really hard to say as the scanner on this thread objects and blocks messages with competitors names.
there is an open source project for the old linksys routers - and a hardware manufacturer that uses that firmware. The hardware has gli in their name

Unacceptable that if the ISP Router has problems, the Mesh Deco S7 become useless and the local network doesn't work.
The worst thing is that this problem has been reported for 4 YEARS ago, but TP Link hasn't fixed this bug yet.
They don't care about their customers, simple as this.
I'll not buy TP-Link anymore, simple as this.
I just made my 1star review on Amazon.
I'm just sorry that I discovered this bug too late for the free return.
4 years and no fix for a bug like this???!!!!

There is a new firmware released in late December that fixes this issue 1.4.0. However, while it fixes this issue it creates a new issue that may be worse. Since the firmware can't be rolled back and it was so impacting to me as my wife and I both work from home, I ended up having to buy a new router. So be warned on upgrading firmware.

@TP-Link I tried different options and found that enabling IPTV/VLAN -> Bridge -> Select Port on Main Router is now providing Ethernet access via the other Port.
Works great so far (last 10 min). Need to wait to see if it holds up.

@SGTM It is not working for me.
Still waiting an official solution by TP-Link.
But it is clear that they do not care....

My BE65 is dropping all WiFi connections when facing some dns problems (NOT lack of Internet, router had 100% time internet), red light and all your wifi is gone, cya. Of course all local connections are down because my deco is set as access point while im using own router, and ive spend whole week to monitor my router, my pihole server, running cables to iot devices to "fix them", and then ive found this thread, oh boy.
But i realised something, they just cant make deco smart or managed, because it would be omada, and deco cant be omada. It have to be stupid app dependent, it will have autosensing, we can all write some funny posts, but i have another week to return this guano to vendor, you may not, i wish you best, and i hope tp link will fix it.

I would definitely return it, they promised this fix thru tech support saying 6/2024, and still nothing, they will tell u what u want to hear so u don't return, it, I say return it asap because they will try to screw u out of a return, by saying a firmware release would be fixed after your warranty timeframe passes. There is no fix they are going to do, it's a bold lie on their part
