Hello, a first post here with an issue I hope someone can help me with.

I have recently set up 3 Deco M4R’s in my home to support a number of WiFi based smart home devices as well as general internet access. This is partly experimental as I am exploring what can be done and how far you can go with such systems. 

So far everything has gone well, the Deco system was quick and easy to set up and made a huge improvement to our WiFi across the house. I have been adding more and more smart devices over the last couple of months and now regularly see 70-75 devices online - I chose the Deco because it claimed to support up to 100 connected devices and I want to see if this true :)

As I’ve added new devices I’ve also named them in the Deco app so I can see what they are doing, replacing the default manufacturer ID with a user name, choosing a device type eg IoT and putting them into some simple profiles to group them. All good and very helpful for managing the network.

This worked fine until I reached somewhere around 57 devices, after which I started losing the information I’d entered on older devices as I brought in new ones - I’d name a new device and save it and then some of the previous ones would now show in the app as their default manufacturer ID (usually based on their MAC address) and all of the user name, device type and profile info gone. 

Is this a known bug or limitation? As I’ve added new devices the list of MAC-only devices showing in the Deco app has grown until I now see about 19 like this, all of which I’d set up and saved correctly before.

I should point out that the affected devices appear to be random, mostly smart lights and sockets but most recently 3 Amazon Echos went as well.

It’s not affecting the network in any functional way as I am using it at the moment but if I was adding tighter controls on some of the profiles such as phone or laptop access it would mean that would all be lost. There are also limits on the number of devices that can be put into a single profile but I can’t find this documented anywhere - only an error when the number is exceeded!

Request to TP-Link: the app should support full naming etc of all 100 devices which the network can support and also please document any limitations or restrictions on numbers of devices it can handle, either in the app, or the cloud or the routers themselves.

Thanks!
