Hi folks,
Hoping someone can help steer me in the right direction. I've had recent issues where my Wifi drops on my Mesh network. I've put a diagram of my setup and honestly my head is melted.
My setup is:
Fibre to the Home via ISP (Eir).
One main Deco M5. This connects to the ISP via PPPOE with the appropriate VLAN tagging etc.
Three Deco M5 nodes.
This was working fine for a long time, but recently I have periods where Wifi connections drop. When speed testing in the Deco app (using a 5G connection on my mobile) I get my full ISP fibre speed. But the nodes drop for some reason and any connected devices to the 3 nodes drop connection.
The diagram below is my setup. All cables are Cat5e or Cat6.
Also I have "Fast roaming" enabled; this never changed. QoS is off / not enabled. I do have a Guest network enabled (mainly to allow 2.4GHz smart devices connect to the network).
