Why Your Cable Modem Matters More Than You Think
Your cable modem is the gateway between your home network and your internet service provider. A quality modem can mean the difference between buffering videos and seamless 4K streaming, between laggy video calls and crystal-clear conversations, and between slow downloads and lightning-fast file transfers.
Many people stick with their ISP’s rental modem, paying $10-15 per month indefinitely. By purchasing your own modem, you can save hundreds of dollars over just a few years while potentially getting better performance and more advanced features.
We’ve tested and reviewed the top cable modems on the market to help you make an informed decision. Our selection includes options for different speed tiers, budgets, and specific use cases. Whether you’re a casual internet user or a power user with a multi-gigabit connection, we’ve got you covered.
