Spider box HD7000 scrambling

[seanmcevoy]

My Spider box HD7000 works perfectly throughout the day but around 6pm all my channels scramble until 12pm everyday.
I have tried to find a solution for this but so far no luck. My quality and signal are both strong plus got fibre-optic internet which is fine. Any suggestions??

are the fta channels working ok at this time ?

what channels are scrambling exactly ?
