Zgemma picture freeze ? attenuators ?

Hi I bought a Zgemma box for use with vermin problems at the start but they have mostly been fixed. One issue still a bit of a bug I am getting occasional picture freeze. This only happens at random times never lasts very long but it can be a bit of a pain if it happens at the wrong time during a Tv show. I have been told it may be fixed completely if I put an attenuator on the cable leading into the back of the box. My question is what size attenuator do I fit.On my router there is a 4db forward path any help would be great TIA
 
Does it happen on FTA channels or is it just on encrypted channels? If it's just on encrypted channels it could be your line. Try another test line and see if that helps.
