Full Fibre - From no issues to regularly slowness

[#1]

Had the service now for approx. 18 months, no issues at all until the last say 3 or 4 months.

The download speeds have dropped dramatically on a daily basis, peaking between 90 and 100, averaging between 60 and 70. This is on both ethernet and WiFi. I have screenshots of 40mb at 2:30pm, 50mb at 18:45pm, 80mb at 3am, there doesn't seem to be much change to warrant peak or off peak.

Few details about my current service;

Full Fibre 500
Hub 2

Email received on activation confirming speeds;

Estimated peak time speeds:
Download: 500 - 550Mb
Upload: 68 - 75Mb
Current line speed: 550Mb
Minimum Guaranteed Speed: 275Mb

I would suggest you contact PN. FF should not, AFAIK, do this unless there is a circuit problem.

I'll have to do that then, it wasn't so much of an issue but now it's affecting day to day.
