After I installed it and authorized online in my Optimum, the internet speed was very noticeable. My pages load much faster and YouTube videos etc play much faster. I bought this device to save the $10 a month I had to pay to rent a cable TV modem. I figured if it doesn't affect speed I'll save at least $10 a month. I'm so happy I did. I am very happy with the end result. I should have known that big companies like Cablevision/optimum online do not and will not offer high speed or quality equipment to their customers. I know the price you pay for a modem is minimal. But we only use them once. I would recommend anyone reading this review to get their own modem and forget about the low budget modems that these cable companies offer their customers. If that doesn't work, try again or until you get a modem that works for you and your ISP. Thank you all for reading this and God bless you.
