Hello, I've been having trouble for some months with my mesh network. I have a set of 3 M4 decos, all of them are connected via Ethernet to my ISP router and are configured in AP Mode. Every now and then I will lose internet connection in my PC which is connected via Ethernet to one of the Satellite decos.

However this connection loss is really weird, as my computer keeps receiving some packets but won't be able to send any. For example, if I'm in a Zoom call I will keep hearing everyone else talking but I won't be able to respond. And a few seconds later I won't be able to hear them anymore. I did some testing last time this happened and I noticed I could ping any of my Decos from my PC, however I couldn't ping my ISP router. Also, any device connected to my ISP router won't have any issues, so I assume there's something wrong with my mesh network.

Let me add a picture of my topology for clarification:

Is there any way I can solve this issue? I can change my topology if its necessary. Thank you very much.
