Good morning

.

What the entire community wants is for you to release a new update that fixes all the problems with the Deco BE63(US)_V2.6_1.3.2 Build 26040912 update.

With all the information provided, it's more than enough for the engineers to resolve these issues.

We kindly request that you release the update soon, because we, as users, have been dissatisfied for over a month now.

I second that request.  I had to replace my 6 month old BE63 due to the bottom two network ports going out and the replacement one I bought updated to the newest firmware and after a day of scratching my head and swapping cables (knowing those weren't the issue) I can't go above 100 mbps.In addition, several things that are hardwired in my network lost internet connection even though their network ports show they are connected.  This is also the first time I decided to use "Router mode" instead of "Access mode" .  I may switch back to Access point mode and see if I have same issues.  All my Decos are hardwired from the main deco and running through a 2.5gb switch except one that is wifi backhauled.  No issues with that setup in last year until this obvious new firmware that no one decided to test in a real world environment.  Not sure if this helps but I am on an Xfinity XB8 modem in bridge mode and using the 2.5gbps port on the modem.

I too have tried  Deco BE65(AU)_V2_1.3.2 Build 26040912 on a mesh of 5 Deco BE65s. 2.4Ghz / IoT devices just would not stay connected.   Was abysmal performance all around.  Lights on all the units were green and I did not get logs.   
I reverted back to a previous beta - BE65V2_BE65V3_multi_v2_SP1_V2-up-ver1-3-0-P1[26022612-rel21001]_2026-02-26_14.44.55.bin.zip and all is good again.

Almost all of the details requested here are irrelevant / inaccessible because the network for the Deco's is in Access point mode.

There are about 74 devices connected, alhough probably 40 on wifi, mostly IoT light switches.  When this happens it is generally the IoT devices that lose connection  (all are 2,4Ghz which I suspect is where the issue lies).

I don't know if they have internet but they certainly don't have connection on the LAN.  If they do connect it is not for long, and there are a couple of devices that just don't manage at all (a Goodwe Solar controller is a prime example of this - it's also 2.4Gz only).
Rebooting devices, the router or all the Deco units does not help.

ISP is Superloop (Australia).  This has not changed in a long time and since this is acess point mode and previous firmware works just fine I dont think its too relevant.

The only way to get the network back to any sort of reliable state is to restore it to an older firmware, which i have done twice.  I 

I'm happy to try a new firmware if required but I just can't be doing with 1.3.2

Hope this helps some

Also, I'd like to add - these devices arrived with firmware 1.16 which did exactly the same thing - 2.4GHz devices failing to connect/dropping. 

I created a post about it here in the forums and David-TP posted a link for a beta version of firmware 1.17 which was a million times better but for a few small issues.

Its like something in 1.3.2 has gone back to how it was in 1.1.6. 

Importantly - this issue only appeared in Access Point mode on 1.16.  I did not try router mode on 1.3.2 because it does not support all i need it to.

I'm also having issues since my kit was updated to 1.3.2. I have three BE65s, set up in series with wireless backhaul in AP mode. One is connected directly to my router, another set up in a hallway, and another in an outside room, roughly equidistant. 

Prior to the update the outside room was fairly consistently able to get speeds upwards of 350mbps. The mesh was set up with MLO enabled, ultra speed mode, and fast roaming and beamforming enabled.

Now the only way I can get a somewhat stable connection over the wireless backhaul over two hops is if I disable MLO and set Stable Mode. The far end device is also having issues showing the connected devices and uplink details in the app, so a lot of the time I can't even say what bands it's using for uplink. It's now having trouble getting over 60mbps. I've even tried factory resetting and swapping two of the devices around to see if there's any difference.

My primary router is a ubiquiti edgerouter-x, the main AP is connected directly to it and when doing an internet speed test from the app I can pull around 900mbps. The recommendations here to disable QoS don't apply to me since I'm running AP mode. Running a cable to backhaul isn't an option, if it were I wouldn't have bought these in the first place.

When I have some time I'm going to see if I can use the recovery method to drop them to a previous firmware, otherwise I might have to look at a warranty return since I've only had them 6 months or so.
