Sly Broadband issues


Had sly broadband in for over 2 years and never had an issue until last night, when suddenly the internet symbol started flashing orange and disappearing, repeating this process over and over. I turned it off and on which had it working again for a few minutes before doing the flashing and disappearing thing again. The online help from sly is useless and i'm in work until 8pm tonight and the wife isn't good with technical things. Anyone on here have any idea what the problem might be?
