Unstable broadband connection

[Dubz]

Unstable broadband connection since changing contract and broadband service as the original sky one doesn't exist anymore so sky put me on a new one. Since this we have had unstable connection, when running diagnostics everything seems and looks fine apart from stable connection says NO. Nothing has changed internally and have had sky engineers out on a numerous of occasions over the past year because of broadband constantly being intermittent and not working as expected. There has only ever been a problem with external hub (main hub sky uses for the community) 

what exactly could be causing this?
