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)

@Mark-R Thanks for the info/suggestions/discussion/etc! My setup is only ethernet back haul. With my old Orbi setup restored, I no longer have any issues. I had an older ASUS mesh setup prior (it had a terrible mesh solution - but in their defense it wasn't their latest MESH solution - unfortunately the experience was so terrible that I don't want to risk their newer solutions). But seemless handoff issues aside, the ASUS system was rock solid as far as overall network staying up. So its hard to believe there is something "wrong" with my setup for the Deco solution to hiccup (only a second to a few seconds) so frequently during the day. Could it really be my AT&T fiber ISP losing connections for split seconds (perhaps the ASUS or Negear simply "ignore" these hiccups and that's why everything appears to be stable) and throwing the Deco into port sensing mode?!
Anyway, I left all my Deco setting as is - so if there is a firmeware update/fix in the future, I can easily swap it back in for a weekend or so to test. But until there is a fix (this thread is 3+ years old?!), I'm going to stick with my "slowish" Netgear Orbi!

Are there any progress on this issue. I got X50-4G, and using it as wifi-router, with my fibre connection as primary WAN and 4G as backup. When my fibre drops out, it uses 4G to provide, but it drops both my wired satellite and my 16 port switch, and only provides wifi enabled devices. Seing as Fixed WAN port already exists on other similar deco devices, this should be implemented on the rest of them.
I'm loving both my X50-4G as main router, and both my satellites (X50 and X50-Outdoor), but this simple issue makes me considering switching the setup, even if I'm really happy with the rest of it.

@Vang1 I thought that was already an option on x50-4g?
I've not got mine set as primary at the moment so can't check, but could swear there was a setting to specify the wan port it listens to in order to flip to 4g? Does that not force the other 2 to lan? Seems a huge oversight if not!

Sadly, I haven't found that setting. It's not under Advanced, not under Offline Detection or anywhere else that I can find.
It's strange, as X20 or X80 with cell backup got that setting, but not X50 does not, witch just doesn't make sense. And since other models already have it, it should be relatively easy to fix.
