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)

@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.

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.

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

According to the Deco XE75 Pro support web page, there is a 1.2.1 firmware update, but the update screen on mine says it's on the latest firmware, although it's on 1.0.3.
I was going to do a manual firmware update, but I'm confused about the hardware version. On the bottom of my router there is a label:
S/N: Y226xxxxxxxxx US/1.6
MADE IN VIETNAM
From this I would assume version 1.6. However, on the web interface in the page Advanced -> System -> Firmware Upgrade, under Online Upgrade, both of my units show XE75Pro(1.0) in the model column. I would expect the (1.0) there means it's version 1.0.
So which one should I download? The one for version 1.0 or 1.6? And why does automatic update say there isn't a new version, when there is one in the product's support web page?

Hi, Deco XE75 Pro V1 and V1.6 shared the same firmware.
The latest version for XE75 pro-V1 is 1.2.1
https://www.tp-link.com/us/support/download/deco-xe75-pro/v1.60/#Firmware
Since it is just released, it might take a while before detecting via Deco APP.
Best regards.

@David-TP Thanks! I have the Deco XE75 running on version 1.2.5. Where do I go to set a fixed port the the WAN? I don't see it on the APP.

Hi, I see now why I don't have this feature. Seems it was added for hardware version 3.20, I have hardware version 3.0 which is still on firmware v1.6.5 from January this year.
Will version 3.0 of the Deco M5 be getting the same upgrade?
Thanks
