I have set up a cline and it shows 'Online' with a green tick - but channels are scrambled - i have rebooted etc - iv read somewhere it can be to do with router settings... how can i look in to this - iv been on the Ethernet setup and when i try to turn DCHP to 'Off' it asks for an alternate one - which currently is prefilled with 0.'s - so what do i enter here to turn it off...
