Hub 4 flashing red light

I’ve woken up today to a flashing red light on my Hub 4. The router admin web page shows the error “Internet (No RF signal detected)”. Broadband and phone service are both down.

I’ve followed the self-service steps (switch off/on at the wall, check cables) but it’s still the same: flashing red light, no service.

I’ve checked the cable outside the house: this is just about 30cm of cable going from the plastic box straight down the wall into the ground, and is completely intact.

VM status is saying there’s no outage in the local area.

Nothing has changed with our setup overnight (or indeed in recent months): no changes to cabling or router location, no power cuts, etc.

The only unusual factor is very strong storm winds overnight but that hasn’t caused any physical damage at home and (as mentioned above) the cable coming into the house is underground apart from the last 30cm or so.

I’m in an M33 postcode.

 Any help?
