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)

@Sus_Deco How is the parental controls (ability to block devices from the internet) on those. That's the best feature of the Decos for me

@TP-Link I agree with the latest poster. It doe NOT make sense for TP-Link to leave this bug in their devices AND tell the customer they can suck it up or go elsewhere.
I have now switched to Orbi and Asus and find the support great and the product even better. Worth paying the extra few dollars folks!

I just setup a PX50 (1.0) a week ago. FW version = 1.2.2 Build 20231226 Rel. 74361. To confirm whether this has been fixed in the PX50, I unplugged the cable connected to the fiber modem and as reported in this thread, I lost access to my shared drives within my home network. So it doesn't appear to be fixed/optimized/etc with my setup.
I was getting intermittent "all devices/network are/is offline" for a second or two. While researching that issue I stumbled across this thread. I've seen other threads complaining about ATT fiber going offline for a second or two randomly during the day. I wonder if that coupled with this auto sensing is the cause of my intermittent network issues...

From elsewhere in this thread I believe the nature of the fix in the px50 is to allow you to use an advanced setting to assign a fixed WAN port and that will stop the autosensing.
Did you find such a setting?

I've got PX50, X50-Outdoor, X50-4G and they all behave differently.
X50-4G has option to assign a port to WAN so 4g kicks in when its down.
PX50 has no option to specify WAN so it throws a wobbler if WAN isnt there.
From the forums I believe the X50 (not PX50) has a way to set the WAN port

@C0deape I can confirm the PX50 doesn't have the option (unless it is very well hidden in options) to assign a WAN port.
Anyway I'm being plagued by a problem that intermittently happens several/many times during the day when the entire network (wireless and wired) goes down for a second or two. I thought it was related to this thread and that during this down time my ISP (AT&T fiber perhaps temporarily went down). But like someone in this thread suggested to put the DECOs (including the "main" one) into access point mode and then introduce another router as the DHCP server. We'll, even in this setup I still get the annoying intermittent network is down.
And FYI I have my setup (both the original setup with the main deco as the DHCP server and latest setup where the DECOs are in AP MODE) with ethernet backhaul.
My previous setup was with the slower older ORBI. I had no issues with the same wired topology. I do have an unmanaged switch in play as well - I can't imagine that is a factor?!

@ClemDaddy have you got anything with a fixed IP on your network, or a device that may also be a DHCP server?
Reason being I had OMADA outdoor access points linked to the LAN with an OMADA controller, and they didn't always play nice. I also had set some devices to fixed IP which I think caused thr 2 systems to fight.

@C0deape thanks for the suggestions. In my original setup, I had not disabled DHCP on the fiber modem, but I don't think that was a factor. My new setup where I have the DECOs in AP mode, I ended up making the fiber modem/router the DHCP server. So for sure in this configuration there isn't any other DHCP server on the network competing. I also don't have any devices with fixed IPs. I do have reserved IPs for machines, but it is still the DHCP server handing those resevered IPs out.
Well, I don't want to hijack this thread with my unique issue. I'll keep searching other threads to see if others have a similar issue, or perhaps I start a new thread. If for some reason the issue ends up being related to this thread, I'll be sure to give an update!

@ClemDaddy AP mode doesn't prevent the deco's from trying to auto sense the wan connection. They are still cloud reliant!
I have now replaced 3 of my 5 decos with open wrt based devices with the decos only in secondary areas (guest spaces) and I don't lose my wired devices or home WiFi when the broadband drops out

@Mark-R thanks for the info. I guess it makes sense that it is still cloud reliant to be able to configure via the mobile app. BUT I can confirm that in AP mode (with another DHCP server in play - in my case my ATT fiber modem/router) you do NOT loose you home LAN when the WAN wire is disconnected. Things seemed to go offline for a few seconds (I almost concluded that the LAN was offline), but eventually I was able access my network shares (despite the WAN wire disconnected).
SINCE I was fed up trouble shooting this nonsense (my wife works from home and can't deal with this unreliability - and I don't want to waste my evenings trouble shooting something that should just work out of the box), I restored everything back to router mode. I disconnected the WAN wire and as reported in this thread, my LAN (wired and wireless nodes) all went offline.
I put back my older Netgear Orbi RBR50. It tops out around 300 up/down - but it is stable - and that's what counts!

@ClemDaddy I think the behaviour varies if you have wired back haul or not. With wired, my m5
master goes hunting a wan if it's disconnected. As
the wireless range isn't enough in my case to
use wireless back haul ALL my decos go offline as the master tries to auto sense using both its wired
ports - which is where I've connected My streaming and home automation systems and als where the backhaul to the other m5s is. At which point it's all in a snotty heap.
if your decos can see each other on WiFi - You may get a different behaviour, but using only wired connections for backhaul I lose everything!
this renders the decos useless to me apart from for guest access to WiFi
