Hi all, ive had my s11 for a few months now and its not a bad box on a budget but recently (since moving my broadband to sly) i keep getting the "no signal" message on most channels, its really frustrating, can SLY block the signal? or is it just a common problem with the openboxes? never had this problem when i was on any other provider. is there anything else i can do to resolve this before buying a booster? please help? i want my telly back! lol thanks in advance for any help?
