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)

connecting the wired devices to the satellite deco's doesn't work. Neither does introducing another router and using the decos merely as access points. None of the workarounds work!!
and this issue has been present for approaching 3 years now.
tplink are willfully selling a product that is not fit for purpose!
inam replacing the decos in the main house with gl.iNet routers and access points because of this issue and have stopped recommending pr buying any tplink products because of the arrogant ignoring of hundreds of customers concerns over this product.
i have emailed the ceo and the uk ceo through LinkedIn and concluded they are utterly oblivious and ignore their clients as their profiles are virtually and my messages have been ignored

So this is probably why I cannot locally access my Jellyfin server without internet? I'll be renovating soon and will have to tear down the entire living room (ISP router will be removed) and thought I could still have all my content available, so to test I unplugged my ISP cable from the main M9plus and my local server wasn't serving anymore :( What a shame.

Hi, yes, It should be and the 1.5.0 firmware on Deco X55/X50_V1 and Deco X80-5G/Deco X20-4G have already supported this feature.
Best regards.

Replying to myself as I have found a solution for my version of this issue. When my ISP is down, I change in Deco app the mode it's supposed to function as. (Mine is in Norwegian so unsure what it's in English) . I change from WiFi mode to access point mode. Then I can access my jellyfin server locally.

@David-TP if it's supported on Deco X20-4G ... are there any plans on supporting this on the regular Deco X20 ??

@TP-Link My fiber ONT died while I was out of the country. I expected my cameras to function since it's all static IP addresses and on a local network. Instead, there was no video footage being recorded while I was out of town. One of my properties was burglarized and thank goodness it wasn't the property with the internet outage.
Had this equipment failure from the ISP caused my entire camera and home automation system to not function during a home burglary I would have filed a lawsuit. This is such an unacceptable problem as a thief merely needs to disable the internet to disable an entire security system. The fact that this has been an issue with such a simple solution as to be able to dedicate a WAN port which doesn't affect the LAN. Why doesn't this get done ASAP?
