I am trying to figure out why I cannot reach 12 Mbps download speed, because I am supposed to have 'high-speed' internet. In order to get a job I have been working toward for about a year, I need to have a minimum of 12 Mbps. I can barely get to 11 Mbps and that takes some doing. I have tried all suggestions to 'speed up' my laptop but to no avail. Please advise. What is my 'high-speed'?
