@TP-Link 

I have the same issue with TP-Link Deco AXE5300 Wi-Fi 6E Tri-Band Whole-Home Mesh Wi-Fi System.  I kept on getting these odd occurances where we would loose internet for a brief period, the wifi would come back but the ethernet was down.  I would play around with the Deco and restart it a few times and it eventually came back.  Here lately it just stopped working.  After reading this article, I connected my ethernet to a satelite and converted my satelites to only wifi backhaul.  It worked as described.  I will see how well it goes but it is a huge bug.  I am going to look at other systems but not for sure what issues they will bring with them.

This defect must be fixed with a user selectable WAN port. Even then, if a port fails, you can redesignate the other as WAN and still use the mesh.

  @TP-Link It's been over a year since reporting, and this problem hit me again yesterday. My ISP had some downtime, and all my home network with many IoT devices and NAS went south - unable to use part of the lights (those behind WiFi relays), unable to access NAS - the whole network f*cked...

 

Can you declare if anything is happening with this topic (with some ETA), or do You just have Your clients in the back and won't fix it...

  @TP-Link Because my Deco units will serve only as AP and I have my DHCP server separate, I assume this is not going to affect me Regardless I am browsing the forums to see all the non-sense you guys are spitting out, this one is pretty epic:

 

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.

 

Seriously???

 

First, every other router on the market has fixed ports. This has and will always be the norm. Trying to re-invent the wheel helps no one. Second, if a port is broken, the unit is broken. You get it repaired or you replace it. Better yet, put the classic 1 WAN + 4 LAN. Seriously what is wrong with the product owner who made all these decisions???

Fix the auto sensing or let the hardware works by itself without WAN or Internet.

Hi, For Deco X50/X55 V1, it might be good news that the latest firmware 1.2.0 has optimized this working mode. Deco will not reselect the wan/lan port until the Ethernet WAN cable is re-plugged.

Best regards.

@David-TP This is a pointless mitigation. The first troubleshooting step for loss of internet, is re-plugging the WAN cable, or power cycling the router. This kicks it straight back into WAN sensing mode and we have the problem all over again. Just allow the user to manually set a fixed WAN port in the settings! It's that simple.

  @Grud 
That is very true. Troubleshooting 101 :(
As pointed out by @GaryParr almost ONE YEAR ago... port selection code is already implemented for IPTV functionality.
Just copy/paste this code and use it to WAN port selection... cmon TP-LINK!

 

Everytime my internet goes down, my local devices loose connection between each other. This needs to be fixed ASAP.

Well said @Grud!!!  I hope people read this thread and see TP's complete disregard (for a full year) of customer complaints BEFORE their upcoming next gen product launch.  Wishing them complete failure!
