If you already own your cable modem, it might still be worth it to upgrade. For example, some users are still connecting to the web with DOCSIS 2.0 modems, which can feel incredibly slow by today’s standards. To put it in perspective: if your current device is a DOCSIS 2.0 modem, by replacing it with a DOCSIS 3.0 modem, you could potentially be getting internet speeds that are 32 times faster.
