Broadband down but testing ok. Phone not working

[Muckbain]

Our broadband is down again this morning. When testing on the service checker, all appears to be ok but nothing will connect at home and restarting the router hasn't helped.

The only orange light on the router is for the phone which is also not working. 

Happened last week and when I checked the router logs there was an issue with NTP sync. Is this something I can fix or is it a sky issue? How do I report a fault?

[Muckbain]

Just checked the router log and the syslog is reporting:

TR69:Connect to ACS failed: Could not resolve host

Send out NTP request to ntp1.isp.sky.com

Spoke to sky and after factory resetting the router, they are sending an engineer to check but it won't be until Tuesday. If anyone has a suggestion on resolving it, please let me know.

TIA

I've got the same problem with my router. They sent Openreach out and they blamed our old router, so we just installed the new one they sent-but same issue still....all solid green lights, can connect but no internet. Just checked and we have the exact same router logs as you. How did it get sorted for you? I've been told to wait 24 hours and 'see if it starts working'
