I have 3 Deco M5s in my network and all was working fine until recently.

In the last couple of weeks my main M5 frequently disconnects from the Internet, usually every couple of days.

When this happens I can still wirelessly access the M5 web interface and my modem router (Archer MR200) web interface via the M5. My modem router is still accessing the Internet but the M5 is not. All my devices are still connected to the M5s

Rebooting either the modem router or the M5 restores internet to the M5.

I have set the M5 IP to static but the problem still persists.

Anyone have any suggestions.

Thanks.
