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 |

I need this fixed for the Deco M4 as well.
Simply not activating auto-sensing until a cable is disconnected is not a useful solution, given that my LAN network would get disrupted every time I need to power cycle the modem.
Come on @TP-Link you already did the most complex thing implementing auto-sensing. How hard is it to add an option to turn it off?

@gilg57 Thank you for bringing this to our attention. i just upvited. I’ve been subbed to this thread for almost a year but tplink still hasn’t fix this issue yet. I refuse to accept their explanation that this is a feature.

Please vote this bug up (button on the left upper corner of the page).
Seems we need to pass 50 to get the support team's attention.

Please also fix this autosensing problem for the Deco M4. Thanks.

@MarkRound yeh they do become expensive AP's and it is true the router side is poor for technically minded users. for plug and play they are ok, but still lots of limitations due to the current bugs

yeah - sad - the product has poor design. I bought 4 of these to provide coverage on a biggish area - but also have a bunch of wired devices and want a 'guest' wireless network that cannot access the wired devices. THe Deco when it works does this ok (although I am beginning to think the router functions are pretty pants! - the device naming doesn't stay consistent and the device list doesn't often match an IP address scan of what is active)
They become expensive Access Points - very disappointing

@David-TP well that's good news - and shows that the problem is in the code (and is fixable there!)
lets hope they have plans for the M5 firmware as well (hopefully they are built from a common code base!)
I will ask as I now have a case open with TP-Link support (and an official reference number!)
