@TP-Link Wow, this thread is still alive. I will say it again: deco wont be fixed, because managed deco would be omada - and that will never happen because of pricing and market positioning. Im glad i returned mine in time (thanks to this thread).

  @nlow2323 

I just thought to check this thread to see how long it had taken for TP-Link to fix this issue.

My last post was in July 2022. I can't believe they are still so incompetent (or just don't care in the least about their customers) to have continued to ignore this.

I gave up on TP-Link totally at that point and replaced my Deco M5s with an ASUS router (that has the ability to add to it as a mesh but that has not been needed yet) and have had not one single problem from that day.

I binned the Decos as I was not going to inflict these on anyone else.

I would advise anyone that's having this problem with TP-Link to just jump ship now as I did.

  @TP-Link 

FIX YOUR ROUTERS!

• 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.

  
Given that the BE65 model released last year, I expected it to have an option to disable auto wan sensing. But instead, I'm greeted with a mess. All 4 Deco models (M9+, X50 X68, BE65) I've owned have different settings and features, some have a Speedtest option while some do not.

Seriously, your workarounds are complete nonsense. No way I'm having a nas in my hallway or bedroom. ADDITIONALLY, THE WHOLE POINT OF A NAS IS SO YOU CAN ACCESS FILES EVEN IF THE INTERNET GOES OUT - WHAT'S THE POINT OF HAVING QUAD 2.5GBE IF I CAN'T ACCESS HOME ASSISTANT OR MY NAS WHEN THE INTERNET GOES OUT? I SERIOUSLY WOULD HAVE GOTTEN UBIQUITI IF THEY WERE SOLD IN MY COUNTRY.

The whole Deco “easy and simple plug-and-play” nonsense completely ruins the experience. Anything logical to have is stripped away in the name of “simplicity.” I would’ve recommended TP-Link routers to my family and friends, but Deco’s obsession with dumbing everything down just makes the whole thing a frustrating mess.

  @BadRouters which doesn't work !

the 'workaround' doesn't work, my deco's are setup as AP's and I have a router from another supplier running open wrt and my decos all go offline if there is no broadband/internet access

  @TP-Link This is not acceptable. Add XE75 PRO to the list. For something labeled PRO, it as far fewer capabilities than my old AX3000. The paywall for features I used to have, and now this is forcing my network to be unusable. 

People with a positive experience tell 3 people, and those with a negative experience tell 10 people. How many customers have you already lost with this flaw? 

  @TP-Link When will Deco BE25 has the fix?

  @TP-Link 

It’s really frustrating that most Deco mesh models don’t have the option to turn off WAN auto-sense or at least give us an option to lock an RJ45 port as LAN only or WAN only.

I’ve bought 4 Deco models, and only the X50 supports disabling WAN auto-sense. Even my new BE65, which is clearly marketed for slightly advanced home setups with a consumer NAS, Home Assistant, etc, still forces auto WAN sensing, dropping connections to my server running home assistant, pi-hole and network storage. I mean the Deco BE65 is literally made for running a home nas with its Quad 2.5gbe ports and super fast wireless back hauling.

Deco is supposed to make networking simple, but the over-simplified settings actually get in the way. Basic options such as disabling WAN auto-sense or disabling LAN isolation on Guest WiFi should be available. These are not “expert-only” features; they’re essential settings for anyone running a home with slightly more than the basics.

Ease of use shouldn’t mean removing control from the people who actually invest in your higher-end products.

Please allow users to disable auto-wan sensing and create guest network without device isolation. At least on newer, still supported deco models. 

  @TP-Link My Deco X20 (v2.0) was updated today (FW: 1.3.0 Build 20250912 Rel. 56370). Unfortunately, TP-Link still hasn’t added the option to set the WAN port, so the long-standing bug remains unresolved.

What was added instead are new parental control subscription features. Clearly, TP-Link had the time and resources to develop that, but not to fix a core functionality issue that many users have been waiting for.

If this problem isn’t addressed soon, my next router will definitely not be a TPLink.

  @TP-Link I finally FIXED my issue with the Deco units.  I threw them in the bin!

My network is working Sooooo much better now.

It's worth trying...... and don't forget to tell ALL your friends about your TP-Link experience!

Bye and thank you Tp-Link!
