The Netgear CM700 DOCSIS 3.0 cable modem is down to $64.99 at Newegg as a refurbished unit. The cable modem is sold by Newegg and comes with a 90-day warranty. This is a very inexpensive price compared to other options where the modem sells for as high as $120 new at places like Best Buy and Walmart. Even other refurb options go for around $95 at B&H.
If you use a cable modem for your internet, you should be using your own cable modem. ISPs tend to charge you for renting their cable modems, and they usually don't even tell you they're doing it. You could be spending an extra $10 to $15 a month for something you don't even need or that isn't very good. If that's true, then the CM700 will pay for itself before the end of the year. Plus, it's pretty much guaranteed to be better than the stock cable modem they gave you at install.
The CM700 can handle download speeds up to 1.4 Gbps, which makes it great for streaming even HD content or playing video games online. You'll get 32 downstream and eight upstream channels, which means efficient internet all around. Plus, the cable modem is DOCSIS 3.0 certified, which most modern ISPs require from a new cable modem.
The CM700 is compatible with a lot of services, including Comcast Xfinity, Spectrum, Cox, and more. You will want to check with your ISP, even if it's one of these, to make sure the CM700 will work. It definitely won't work with some networks like Verizon.
Get super stable speeds with the Gigabit Ethernet port on the back or connect a wireless router for Wi-Fi around the house. You'll want something like the TP-Link Archer A7 router for $68.99 at Best Buy. It's a super affordable router that won't disappoint with its coverage.
