Cable Modems

Cable modems are needed to connect to your TV and internet service provider. As opposed to regular modems, cable modems have a coaxial cable port to connect with the cable input from your wall, as well as ports for Ethernet cables. Since modern data plans can have up to eight downstream channels coming into your home, a coaxial cable modem is an efficient tool in your home’s Wi-Fi network because it’s able to maximize throughput using one big cable instead of individual ones. Best Buy carries a large selection of DOCSIS 3.1 cable modems for you to choose from.

Perhaps you already own a cable modem and you’re unsure whether you need to upgrade to a new DOCSIS 3.1 modem for your Wi-Fi network. To give you a clear answer, think about how well your current device is operating and even run an internet speed test to give you a better idea. If your internet speed has slowed, drops off frequently, or has trouble connecting to the internet, a high-performance internet cable modem could improve your experience considerably. Advanced technology DOCSIS 3.1 modems bond multiple data sources together while still accessing the individual channels’ information so that their data loads are balanced more efficiently. Those concerned with saving space and money might choose a cable modem router that combines two devices in one compact unit to ensure there aren’t any delays in receiving and displaying your audiovisual entertainment. 

After you’ve chosen the best cable modem for you, schedule a home network setup service with our professional Geek Squad® team, or you can always go the route of DIY if you’re confident in your abilities. To preserve the life of your cable modem, plug it into a surge protector that prevents damage to your electronic devices. Cable modem routers tend to run hot, so it’s a good idea to turn them off when they’re not in use. This helps to save energy as well, which is key for sustainable living. If you don’t want to forget to shut off the power each night, use smart plugs and outlets to do the work for you. Too much humidity in a room can also reduce the longevity of your coaxial cable modem, so consider investing in a smart thermostat to regulate your home’s ideal climate.
