Hi David,

Have you got any link to get these firmware update before anyone else? Because Deco download center shows old version.

Thanks for your answers.

Hi David,

Your technicians still have not provided a fix for 1.5.0 or any feedback as to any progress with the situation, and to be fair it's been a while now. 

So I tried again to downgrade to 1.4.5 to one single S7 via ethernet direct to the computer. All I got was an "uploading" box for ten minutes so I gave up. After that I downloaded 1.5.1 but a message in red flagged up that it was an invalid file, so I did not push the upgrade button?

My system consists of one X50-PoE as the main and three S7s as slaves.

If you or anyone out there has a guaranteed step by step solution to downgrade to 1.4.5 I would be very nuch obliged.

I'm still facing connectivity issues with the released firmware 1.5.1 Build 20240711 Rel. 38529. Manual resetting the Deco S7 units are necessary to restablish the degraded performance.

Are you guys working on it? There are several complains similar to mine. I do not want to downgrade the firmware due tot he IoT Network feature.

I can help to grab debug data if you instruct me.

Like other users, I am experiencing connection issues with the last available beta firmware. I am being forced to daily restart my deco to reestablish the degraded performance. It has been a couple of months since the last beta version's launch, with many clients complaining and no movement from tp-link side.

It's very frustrating to receive this treatment from the company since I've been a tp-link customer for a long time.

I think it's time to consider other router brands...

1.5.2 is available. I was on 1.5.0 but had no real issues, besides needing to turn off and on my main unit now and again.

I installed 1.5.2 yesterday, no issues to relay so far.

Yesterday I received a notification from Deco APP to install version 1.5.2, which I did.

I'm not using any IPV6 on my network, my main Deco is connected with the ISP modem which is making a PPPOE call.

The thing is that since I installed this update, looks like my Decos keep constantly losing connection to each other. My desktop computer is connected throught the cable from the Deco in my office, and suddenly my internet/network just hangs. I'm unable to ping other devices in the network or access anything on the internet.

When this happens I open the Deco app in my phone and see that the Decos are offline and only the main one is online. If I turn the wifi on and off and try to connect throught the wifi to the main deco it works.

After a while they start working again, but this keeps happening many times a day.

I rebooted them, remove them from the power outlet for minutes, but nothing helps. I was using 1.5.0 before, this also happened but in a much less extension.

@David-TP 
I'm having exact issue with 1.5.2 which @EddFigueiredo has. Main deco stays online but my 2 satellite decos somehow freezes and becoming unresponsive to network requests. Their lights turns to red in that moment and impossible to connect to those devices. They are recovering themself after a couple of minutes. Never had such an issue with 1.4.5. I feel like this is a dns/dhcp issue between the devices. I'm using custom signal source feature and choosing the sources manually which is published within 1.5.x versions. That may be the reason too.
