We access the internet at home on a single laptop, and as there is a limit on our Broadband allowance have a metered connection set up. We only connect to the internet briefly each day, and the laptop records data usage of about 2.7 GB a month. However the Broadband usage showing on my Plusnet account is three times the data usage shown on my laptop. This seems like a big difference, and we are wondering why this could be happening?
My first thought is do you have any other devices that use the broadband at all that may not be obviously using data? Such as Sky on demand boxes, mobiles ... ? And the laptop that's recording usage, what's the program/app called that records the usage for you?
