Hey, we can get some details to do the further analysis first.

1. What is the led status of Deco when you lose internet? Do both wired connections and wireless connections have the same issue? 

 

2. When it stops working, please connect your computer to the main Deco directly and verify whether you can access internet; in the meantime, try to connect your PC to the modem, bypass the Deco and test whether it works.

 

3. Try to simplify the network diagram, in other words, connect the main Deco to the modem only with other slave Decos unplugged; and is there any heavy traffic network activities before it crashed? 

 

4. You can swap the locations of the Decos or switch the slave Deco to the main Deco to give it a go.

Thanks Kevin for your reply!

Q1: As far as I remember, the light on the main Deco was still green, but anyhow the wireless still worked on the main Deco when I checked with my phone close to the main Deco. Only the slaves are indicated as lost in the app, and their led is red. The wireless clients conneced to the slaves show an exclamation mark close to the wireless symbol.

Q2: As the wireless functionality still worked on wireless client (my phone) when connected to the main deco, see Q1, I did this more or less...

Q3: I have removed all other switches from my network and cannot simplify it more. The main Deco is directly connected to the router (as well as two servers and a backup server). The rest of the network (wired and wireless units) is connected to the internet through the main deco. See the description of my network in my original post.

Q4:I have put so many hours in reading posts, switching deco's, buying new TP-link switches, simplifying the setup, that I am reluctant to do it all over again. 

To me the whole system is quite buggy. Sometimes the app tells me my phone is wired connected to the deco (!), or doesn´t show upp in the list at all, while I am using it.... The stability was improved when I put the rest of network in series with the main deco though. But apparently, there are more bugs.

It looks like the system needs an overall check of the firmware.

@RalfH  here is an example of the Deco system claiming my Samsung S8 is wire connected to the system. Right now, the Deco claims I am not connected at all, while I am connected to the wifi.

Any feedback on these obviously wrong statements?? Sorry for the Swedish language, but I think you understand ....
