We have had fibre for a while, about 6 months ago I upgraded the fibre package to 78MB,
For a while everything seemed fine but over the last month we have SLOW broadband for periods of time, and I mean slow, on all connected devices. Restarting router helps for a short period but it still gets worse, lower than what we got when we were on 30'ish MB.
I do broadband tests and I'll get 55MB then 10 mins later I'll get 4MB...please help
