Updating modem speed
Also don’t buy one if you use your cable provider for telephone service: The models we cover here don’t have phone ports.
If you need one that does, check to see which “telephony” or e MTA modems your ISP supports, and if the company allows you to buy your own.
(Spectrum includes the modem-rental cost in its current Internet plans, but if you haven’t changed your plan since the Time Warner–Charter merger in 2016, you may still be paying a rental fee; give Spectrum a call to see what your current options are.) Unless you have gigabit-speed Internet, you can expect to pay around to for a modem, which means you’ll save money in less than a year.
Many ISPs rent out modems that double as wireless routers, which means that if you want to buy a cable modem, you may also need to buy a wireless router if you want Wi-Fi in your house.
That way, you’ll be sure to get the best option at that time.
Some newer modems support 24 or 32 downstream channels, which could improve the reliability of your connection, but your ISP has to provide those channels for you to get better speeds, and ISPs rarely share channel-bonding information with the public.
Every revision to DOCSIS has improved performance and added new features.
Just as important, it’s compatible with the most major cable Internet service providers in the US—including Comcast, Spectrum (formerly Time Warner, Charter, and Bright House), Cox, Suddenlink, Cable One, and WOW—which gives you the flexibility to switch providers if you move (or if you’re lucky enough to have multiple ISPs to choose from).If the CM500 is out of stock, get the TP-Link TC–7620.It has just as much ISP support, and it should work on most plans that top out at speeds of 300 Mbps.Unless you’re on a very congested network with constant slowdowns, you likely won’t notice a huge difference from added channels on slower speed tiers.Gigabit internet is rolling out broadly over the next few years.
