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 |

Absolutely horrible design and customer support on this front. All this time and still no solution to dedicate a port for WAN? I have recommended the deco devices to several people but never again. This is unacceptable as I have to have my LAN working when there is no internet. NAS, Server, Printer, etc. for business purposes. Please release a firmware update for the x55 deco to address this issue.

@TP-Link Will you please give us an eta on when WAN port assignment will be added to each deco model?
" It is also planned to support manually fixing a specific Ethernet port as WAN post on the Deco APP later" Later is totally unacceptable for a bug like this. Give us a timeline. It has been three years since this bug was reported to you.

@TP-Link Very Dissapointed. It's 4 almost years. I am long time TP-Link user. I will never us TP-Link again.

This is a BUG! Needs to be resolved ASAP.
Deco X55 on latest firmware STILL does not have the option to disable auto sensing.
It is inconceivable that a LAN network is impacted by WAN access availability.

@TP-Link Found a firmware update 1.4.0 Build 20240718 Rel. 44385 - seems to have a fix for this and allows to set WAN port. However, since installing it the router seems to lose connection intermittently. I have tried restarting/rebooting system still occurs. doesn't appear to be ISP dropping but router dropping. Appears to maybe be a bug in this new firmaware.

@Ronix73 Unfortunately this solution does not work either. As soon as the WAN link to the router drops, the Deco mesh network drops.
There is NO SOLUTION other than to buy a new mesh system taht works as it should.
When you also add that the US and Australian governments are looking to ban TP-Link products due to allegations of spying through their devices, this is a good case to remove ALL TP-Link devices and buy elsewhere.
