@Rioja I downgraded to 1.4.2, the one hosted on the first page of this thread. @onemoar You can downgrade, you just can't go from 1.4.x to 1.3.x. 

@Colson  But how did you do it please. Thank you.

Belkin Wemo Light Switches are very unreliable with the new firmware 1.4.4, they can only connect to certain Decos and I see "associated / disassociated" messages in the logs. Does this firmware address unstable connections with Wemos?

I see others have mentioned smart devices / light bulbs / etc. are having trouble with 1.4.4 :(

UPDATE: I took the plunge and downgraded from 1.4.4 to 1.4.2 on my M5 and my Wemo lights show back up!

I think there is a major incompatiblity with M5 1.4.4 and Belink Smart Switches - it kills network connectivity. My network has a mix of M5 and M4R. Immediately after reverting to 1.4.2 all my Wemo lights showed back up and are now functional again...

@coolspot18 Same thing happened with me and my Globe lights. My home kit enabled EVE switches continued to work under both. 

@Colson Thanks Colson. I have returned to beta 1.4.2, because with 1.4.4 I had had some punctual loss of internet and also abandonment of wifi from any of the family phones. Which never happened to me with any firmware.phone. Which never happened to me.

Cheers.

I purchased the deco m5 v3 system a week ago, as soon as I made its configuration the decos were updated to version 1.4.4.

It worked for 1 day and then the problems started. The deco remain connected but the devices have the navigation flaws already mentioned by the other users.

I have about 26 devices connected to the deco with a large part (20) IoT devices that practically do not transmit data.

When you restart the decos the system returns. After some time the problem recurs.

I've tried in router mode and ap mode and in both cases the same problems happen.

Unfortunately in Brazil a deco system is very expensive to present this type of problem. We need a solution!

If possible, provide new firmware or the downgrade tool.

I returned my archer c9 and kept the decos until a return. Unfortunately I have no way to return them to the seller.

I am waiting for a return.

On the first page of this thread, there is firmware 1.4.2, install that onto the M5 and it is very stable. 

@PieroSimonassi This isn't meant as an insult, but for me, it took three attempts to get the downgrade to take. If you haven't already make sure to double check the firmware version installed.
