Speeds of 10 Mbps and higher are good for gaming, but what you really want to consider when choosing an internet service for gaming is latency, or ping. Latency is the measure of how long it takes for your device to communicate with the server and is the main contributor to lag. The higher the ping, the more likely you are to experience lagging. Shoot for an internet service with latency below 100 ms.

Yes. Fiber-optic internet is a completely different technology than DSL or cable internet, and therefore requires a different type of modem. In many cases, you can get the required modem from your internet provider at no extra cost.

Download speeds of 25 Mbps and above are considered broadband speeds, and can handle most online activities including streaming and gaming. For households with multiple devices using a Wi-Fi connection, speeds of 100 Mbps and higher are likely to offer a better online experience. Learn more about what speeds are best for your home.

Upgrading your internet plan or switching to a new provider that offers faster internet service is the best way to get significantly faster speeds, but that will likely also come with a price increase. To get faster internet without changing your plan or provider, upgrade your internet equipment or reduce the number of devices connected to your network.
