Mark has a laptop and suddenly everything is slowing down, and his youtube videos are skipping to the point that it's unwatchable. Leo says that YouTube being slow may just be the Internet connection. Since Mark has cable, if everyone is watching Netflix at night, the Internet will really slow down. There's only so much bandwidth to go around. The ISP denies it, but Leo thinks that the problem is with the cable company. Upload speeds shouldn't surpass download speeds. Ask for a new DOCSIS III Cable Modem, which is the latest and fastest modem.
