My Macbook only connects to internet in the evenings

I have recently moved home and signed up to Sky Broadband, our phones and Playstation connects anytime of day no problems at all, but my Macbook only connects in the evening, even early hours of the morning its fine, I wake up in the morning and connection is lost and I cannot reconnect all day until around 6pm. Has anybody else had a similar problem? I work from home and am starting work again next week! Not sure if its my laptop or the broadband which has the problem?

Many Thanks in advance!
