Wifi and Ethernet dropping daily but hub stays blue

[darrenjhopkins]

I have Fibre 2, FTTC and a SmartHub 2. About 5 weeks ago the Wifi and Ethernet just stop working randomly on the router. I can connect to the admin page which says it it connected and the hub light stays blue. 

Had a Cube engineer out who changed the master socket, nothing changed. Got a new SmartHub 2 sent out, nothing changed. Had an OpenReach engineer here when the problem happened. He tested the line, got a sync and couldn't find a problem on the infrastructure. Even he couldn't connect to the Wifi or via cable. Rebooted the router and it all worked fine again!

Any thoughts? Could I send logs which may help?

have you replaced the cable from the master socket to the hub and ensured the cable is secured at both ends?

as you have replaced the SH2 unlikely 2 hubs with same fault

[darrenjhopkins]

New everything! New hub, new cable, new master socket. 

It's almost as if something "happens" to the hub and it stops passing connection through. 

All the devices on my Wi-Fi network stay connected and they can ping each other, they just can't ping anything on the internet. I can also add new devices to the network and they get assigned a local IP address but also can't access the internet.

What happens when you  depower the SH2 then power it back on?

[darrenjhopkins]

Like magic, it all works again fine when I reset, pull the plug or press the power on/ off button. Very confusing.

Are you switching the hub off overnight? if so then don't, it screws the line speed up

[darrenjhopkins]

It never gets switched off.

Line speed is fine when it is working. Even when not sending internet to the devices the hub is in sync and showing blue. Speed is not a problem, lack of complete internet is. Thanks!

Hello.

Did you get this problem resolved?

I have exactly the same problem as you described.

Yes, I did get it resolved!

I resolved it by cancelling my BT line with (on a good day) 20 down/1up and got Starlink instead!

"New everything! New hub, new cable, new master socket. "

New power supply?

It could have an intermittent fault that is only apparent when it has been on for a while.

Possibly a slight drop in the output voltage? I have known that to happen with these plug in the wall types: they show the correct voltage open circuit with a meter, but fail when conected to equipment.
