How to Save Money with Charter Spectrum

As the cost for reliable internet service goes up every year, nearly everyone is interested in easy ways to save on those expensive cable internet bills, especially on those extra fees that get tacked on in addition to the service charges. If you’ve ended up here, you’re likely looking for ways to either upgrade your internet service OR save money on your bill. We can help out with BOTH with one easy change! Simply by owning your modem and router with Spectrum Charter, you can start to save anywhere from $5-$10 on every Spectrum internet bill going forward! The tricky part is finding a Spectrum compatible modem to fit the bill so you can return your rental equipment.

Unfortunately, most cable carriers don’t make this process too easy for their customers. Charter Spectrum has strict compatibility rules for which models are permitted on their network, and it can be a pain to activate with their customer service since some of their support reps refuse to provide technical support if the device you’re using is not one of their rentals.

We know firsthand how difficult it can be to find the right modem for your service! That’s why we pulled together this Charter Spectrum modem list of that includes all equipment currently known to work with Spectrum, Time Warner Cable and Charter cable. Every Spectrum modem listed on this page has been tested & confirmed to work with and perform well on any of those three networks. Our testing and assessment of the Spectrum Approved modems listed here include verification of technology compatibility, real world maximum speed, and IPv6 compatibility as well as customer reviews for each product mentioned. We want to ensure that you have an easy transition off of your rental so that you can save money and feel good about your upgrade!

Even though these modems are compatible with Charter Communications, we still always recommend contacting Charter Communications prior to purchasing to ensure the modem you get will meet the speed & service requirements of your Charter Communications internet plan.

Best Spectrum Charter Modems

Now that we’ve narrowed it down to what models work well with Spectrum Charter, we can take a look at some of the more common features that are included with most models so that you understand which ones you may need and have a better idea of what each of them are for. Here is a list of things to consider when deciding what models would meet your needs best:

  • DOCSIS Version (3.0, 3.1, etc.): Most cable providers are currently allowing DOCSIS 2.0, 3.0 and 3.1 models to be activated on their network, however some providers limit the number of DOCSIS 2.0 devices due to network infrastructure upgrades that have made them obsolete in recent years.
  • Max Wired download Speeds: This is the maximum speed your modem can support with a wired connection via ethernet cable. Generally the advertised speeds for this specification will be about 10-20% higher than what you’ll experience on a normal day using the device in your home. Because of this, we recommend going with a model that supports speeds at least slightly above whatever your internet plan provides.
  • WiFi / Wireless: Is the device you’ve picked out a modem router combo, or just a modem. If your device does not have WiFi built-into it, you’ll need to go without or purchase a separate wireless router to provide your home with WiFi. In many cases, it can be better to purchase a separate WiFi router to use alongside your modem. This can make troubleshooting common network problems a bit easier, as well as allow you to upgrade your WiFi in the future for much lower cost.
  • Beamforming / Beamforming+: Beamforming is a wireless technology that boosts your wireless signal out to your devices, adding more signal strength to your WiFi networks and allowing you to connect from a further distance.
  • Dual-Band WiFi: Dual-Band wireless is a technology that splits your wireless into 2 separate WiFi networks. These networks are broadcast at slightly different frequencies which give you more flexibility with your network. One frequency is usually broadcast at 2.4GHz, which is better for signal strength, range and going through walls. You’d want to use this network for accessing from across your home, or from your mobile devices. The other network that’s typically broadcast is done at a frequency of 5GHz. This network doesn’t penetrate through walls as well, but offers much faster speeds. We recommend this for stationary devices that are somewhat close to your router such as a TV, media streaming device, printers, desktop computers, etc.
  • Max WiFi Download Speeds: Your max WiFi download speeds may be totally different from your max wired download speeds, and that’s okay! We often see a modem that supports speeds of nearly 1000Mbps but its wireless speeds only go up to N450 (400Mbps). Just be aware that just because a modem says that it’s speeds are Gigabit, does not mean that the WiFi will too.
  • Telephone Service: There are a few devices that are still made that support landline phones, however most of them don’t support speeds higher than 400Mbps. If you’re stuck between the rock and hard place of needing a landline phone, but wanting higher speed internet as well, ask your provider about activating 2 separate modems on your account and having the phone portion of your service on one device, and the cable/internet/WiFi on another. You may need to speak with a higher tier of technical support to get it done, but it’s something that can absolutely be done.
  • Backup Batteries: This is more of a luxury feature in our opinion. The battery backup serves as a protection for your phone line only, during loss of power for up to 16hrs (with equipped 16hr battery). Keep in mind that this just keeps your phone on, not the internet, and only works if your landline phone itself has power still. These are fine, but we would actually recommend taking the plunge and investing in a larger surge protector/battery backup combo that will cover more than just your landline phone service, and for more than 16 hrs.
  • Ease of Activation & Setup: This one’s a no-brainer. You definitely want to pick out something that you’ll be able to set up yourself. Many cable internet providers don’t like to offer technical support for customer-owned modems and routers, so having one that you can DIY is really important. Luckily, if you ordered from we offer free technical support with each order, so if you do get stuck, or go into your activation totally out of your element, just contact us and we’ll help you out!
