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 Deco BE65-POE_v1 Deco BE65-Outdoor_V1 Deco BE68_V1

Dear forum members, it was nice being with you...
It was sad to see that TP-Link:
- abandon its customers
- don't care about correcting unacceptable errors for a mesh system,
After years of problems & swearings, I found the definitive solution.
I finally threw the deco S7 in the bin and bought a new mesh system.
Ps I switched to Fritz!Mesh
Wow!!!!!
More expensive but an epochal turning point.
I recommend it to everyone. top software and applications, maximum configuration, works great with HomeAssistant and even the Mesh is definitely better, another planet.
Goodbye TP-Link

@TP-Link I also find this astounding that this LAN not working without WAN issue hasn't been addressed in such a long time, including on high-end devices like the BE95. Is there any plan to fix this in the near future?

I highly doubt that this will ever be fixed... they never reply!
After going through 4 models since 2021, none of the them have included the option to turn off the auto wan/lan switching... I originaly got these stupid deco systems thinking that it would integrate nicely with my tapo iot devices but whenever the internet drops out, my wired iot devices suddenly disconnect, which is annoying... Every deco model advertises up to "hundereds of devices" but with just 50 wifi clients at home, even the be65 requires reboots every week...
Its a shame that tp-link prioritizes releasing new products and marketing them rather than improving the firmware of the existing or even the new products....

Well, I do reply.
And the 1.3.0 firmware here has supported fixing the WAN port:
Deco BE65/BE63/BE11000_V2_1.3.0 Added DoH & DoT, Speed Limit and Internet Backup
Best regards.

Hi, Deco BE95 is also planned to support fixing the WAN port.
If you don't mind, could you please send an email to support.forum@tp-link.com?
The engineer might be able to find us a workaround first.
Best regards.

Hi, the 1.3.0 hasn't been officially released.
Based on the user feedback, it is a great firmware that can't be missed, and it has also added many other new features, like DoH/DoT and Internet Backup.
Best regards.

1.9.1 firmware on a deco M5 definitely does NOT allow fixing of the WAN port and definitely does shutdown if the broadband connection is lost (phrased this way as my M5's are configured as access points not routers and therefore I have another device as a router)
