Optimum FAQs

Optimum has plenty of cable internet plans to choose from, but before you go picking the first one you see, there are several important factors to consider. For starters, you'll need to have an idea of how fast you want your internet speeds to be. If you're an avid online gamer or stream a lot of Netflix, odds are you'll need faster speeds. It's also important to consider how many users and devices are typically connected to your internet at the same time. The more people using your internet simultaneously, the more your internet speeds can potentially be slowed. The amount of included data you need, contract preferences, and your budget are also important factors when deciding on an internet plan from any provider.
Don't be too alarmed if these speed test results are a little above or below your plan's listed speed. Several factors can vary the results of speed tests, but in general, internet speed tests like the one on this page are a great way to estimate your current provider's upload and download speeds to your devices at your current location. To make your speed test results as accurate as possible, be sure to follow these steps prior to beginning each test: restart your modem and router, stop any internet use, restart your computer, and clear your web browser’s cache. If your speeds are consistently much lower than expected, you can reach out to Optimum at the appropriate phone number above for help.
Internet speed tests (including the one on this page) generally take less than a minute to report your current upload and download speeds.
If you're looking for faster internet with your Optimum service, try boosting your internet speeds by moving your router to a more central location closer to your computer, adding a WiFi extender, and rebooting your router/modem. If you're still not satisfied after trying those changes, compare other internet plan options that may be a better fit for you using our search tool.
Download speed is important when you are downloading anything from the internet such as photos or videos. Upload speed is involved when you are uploading content to the internet via activities such as live streaming or video calling.
Slow internet connection can be caused by many different factors. You may want to consider increased internet congestion, website/server limitations, corrupted web browsers, adware or spyware, wired vs. wireless connection, the type of modem you're using, your computer's processing speed, and your operating system's efficiency if you are struggling with slowed internet speeds. You can also contact Optimum at the appropriate number above if you have specific questions regarding your internet speeds.
