I installed a deco x20-4G modem with updated firmware 1.1.4 build 20230714 rel. 2881. This modem is connected to a poe switch where are connected a nas and two deco x50 poe units with firmware 1.2.4 build 20230731 rel. 64427.

At home I have installed, among other things, around 40 Shelly devices that connect via 2.4 GHz wifi to the 3 deco units.

Everything was working fine until two days ago when I noticed that:
-I can connect to the NAS with my mobile phone only if I am connected to the x20 deco, when the mobile phone connects to one of the x50 units (obviously in a completely transparent way given that the wifi network SSID remains the same as it is a mesh network) the nas becomes unreachable from both iphone and ipad.

-In the same way, through the Shelly app I can only control the devices connected to the same deco unit as the mobile phone. In practice, the app shows all the devices as they are in the cloud but the commands cannot be transmitted locally unless under the same deco unit. The devices are connected to the internet because I can remotely control all of them with my cell phone.

-A different problem that has arisen is that by inserting the client IPs in port forwarding and in reserved addresses these are saved with the wrong IP (e.g. 192.168.1.109 is saved as 192.168.0.109), this has always been happening for two days because I have opened ports and reserved addresses previously and they were saved correctly.

So yesterday I did a reset of all three deco units and reset my configuration, however the above problems reoccur immediately and in addition to these the devices that connect via wifi are no longer entered with their name ( shelly1plus-xxxxx etc.) but most are labeled UNKNOWN.

The situation creates particular discomfort for me because I would also like to configure the home assistant system that I have installed in the NAS (Qnap) but only the shells connected via WiFi to the x20-4g unit (the same as the NAS so to speak) are detected.

Even to access the home assistant I can only access it if connected via wifi to the x20 while I have no problems doing it via DDNS by selecting the port I forwarded.

I hope to find a solution or I have to change mesh system.

Thank you!
