Dear all,
Since 27th July my broadband has been terrible. On the M200 Fibre Broadband package. Speed has fallen to basic service levels and failed DNS queries are hovering around the 15% mark. Here is my SamKnows whitebox download trace to show the issue. Note that I was already only receiving 75% of the advertised service since the last engineer visit .
Attaching the required Superhub log and power details (Superhub 2ac):

Thanks for the suggestion. I checked and there are no faults reported for my area.
In troubleshooting, so far I have moved the SuperHub into router mode, rebooted it, checked the physical connections and cables, and restarted the various boxes connected to the SuperHub.

After the reboot yesterday, things have gone back to the ~150Mbps I was experiencing in July. Progress 🙂
Thanks for the input everyone!
