I bought a new deco m4 to add it to my 2 deco E4's. I made tge M4 the main Deco in order to benefit out of the 1gigabit ports. When I download something or d I a speediest the M4 gies red and all connections lost. I have to reboot to get it working again. I have tried resetting my router and deco m4 multiple times. I have 1 Deco M4 and 2 Deco E4 in my network.
Please help. All worked well when I had the 2 Deco E4.
