I've recently updated the firmware on my Deco M5 devices (1.4.7 20200725) and since then my internet connection drops. The Decos' LEDs are red when this happens, and although my Plusnet Hub One router is still connected to the internet (LED stays blue as it should), it and the Deco M5 require a reboot to get everything back up and running again. This happens regularly, and almost like clockwork at 9.30 am, 1.45 pm and again at 10 pm. I'm in access point mode.

I've turned them off for a few days and relied on the Plusnet router only - no trouble. Everything else is as it was pre-firmware update.

Turn the Decos back on today - same issue.

Any ideas?

Cheers.
