Spectrum doesn’t play around with “bargain” slow speed plans that are sure to disappoint anyone living in the twenty-first century. The slowest plan offered by Spectrum whizzes along at speeds up to 100 Mbps, which is ample speed for a household of three to four people to stream video on multiple devices. Hopping up to even faster speeds up to 100 Mbps (wireless speeds may vary) for $49.99 per month for 12 months, Spectrum gives you more bandwidth for gaming and faster file uploads and downloads.

In some areas of the country, Spectrum offers speeds up to 940 Mbps (wireless speeds may vary) for $109.99 a month for 12 months. In other places, up to 100 Mbps (wireless speeds may vary) for $49.99 a month for 12 months is the fastest available. That’s because Spectrum uses cable infrastructure originally installed by three different telecommunications companies to deliver cable internet to 41 states.

Spectrum’s parent company—Charter Communications—bought out two other telecommunications companies (Bright House Networks and Time Warner Cable) and combined them to create the third-largest telecommunications company in the US—Spectrum. In some areas, the infrastructure is built to enable faster connection speeds, which is why there are different Spectrum speeds available across the country.

Spectrum Mobile broadband

Spectrum Mobile utilizes the most reliable 4G LTE network, which we assume is Verizon. Connection speeds for 4G data vary based on network congestion and your proximity to cell phone towers. Verizon’s 4G LTE data averages speeds of 5 to 12 Mbps, with upload speeds topping out around 5 Mbps. That’s usually fast enough to watch YouTube videos and browse the web while you’re sitting on the train during your morning commute. (Just keep those earbuds handy.)

Plus, if you’re a Spectrum Mobile customer, you’ll also have access to Spectrum Internet’s network of WiFi hotspots, since Spectrum Mobile is only available to current Internet customers. You can use these WiFi hotspots around the city to keep data usage low on your phone.

Internet Speed Test – Cable Speed & Bandwidth Test Spectrum

With Spectrum Mobile, you can pay for data by the Gig ($14/GB) or pay for an unlimited data plan ($45 per line). By-the-Gig data can be shared with other phones you have on your plan.

As far as data speeds go, keep in mind that if you opt for the Unlimited plan, you will experience reduced data speed after the monthly 20 GB threshold.

About our Spectrum Internet speed test

Our Spectrum Internet speed test will show you how fast your Internet is actually clipping along—which might be different from the advertised speeds. By connecting to servers near you, our speed test gives you the most accurate results possible.

Internet speeds vary throughout the day, so make sure you try the speed test during peak and off-peak hours to get a good idea of how well your Internet is performing. You can also test your WiFi from different rooms in your house to determine where you have the strongest signal. If you have dead zones, adjusting the location of your router/modem can help.

How does the Spectrum Internet speed test work?

An Internet speed test will show your actual connection speed in megabits per second (Mbps).

The Spectrum Internet speed test will prompt your browser to attempt to download a test (or dummy) file. The speed test will keep track of how long it takes for your computer to download this file. Don’t worry—the file is harmless. This size of the file is then divided by the download time to calculate your download speed in megabits per second (Mbps).

Next, the speed test switches things around to upload the same file, calculating how long it takes. The file size is then divided by the upload time to calculate your upload speed.

Your latency is measured in the test as well. Latency is also known as lag time, and a high number is a bad thing here, folks. To test for latency, a signal known as a ping is sent from your computer to your internet server, which then boomerangs back to your computer. The faster data can travel, the lower your latency. The longer it takes for a ping to travel this distance, the higher your latency score is. Low latency scores of 20 ms to 40 ms (milliseconds) is fantastic. A high latency (over 70 ms) can give you noticeable delays when you’re doing things like playing games online.

Keep in mind that advertised speeds are listed as “up to” and are not a promise of actual speed. Still, you should be getting close to the speed you’re paying for most of the time. If not, contact Spectrum and let them know.

Test

For the best results, we recommend using a wired connection to your internet (with an Ethernet cable). Then try it on your WiFi. If there’s a big difference, you might have problems with your router/modem.

If you aren’t getting the speed you need, try resetting your modem. Powerpoint similar. If that doesn’t work, you can contact Spectrum about it. And if you still can’t get the speeds you need, it’s easy to cancel Spectrum and switch to another provider since Spectrum doesn’t have contracts. But keep in mind that a new provider will probably charge an installation fee, though, and may require a contract.

Spectrum Internet speed FAQ

How fast are Spectrum Internet speeds?

Spectrum Internet speed packages vary based on your location. In some cities, there are three plans, up to 100 Mbps (wireless speeds may vary) for $49.99 a month for 12 months, up to 400 Mbps (wireless speeds may vary) for $69.99 a month for 12 months and 940 Mbps (wireless speeds may vary) for $109.99 a month for 12 months.

Comcast Speed Test Business

According to our data, three of the five cities with the fastest Spectrum Internet connections are located in the DFW (Dallas–Fort Worth) area in Texas, with two others located in Southern California and Long Island, New York.

The slowest Spectrum Internet service is in Montana, Idaho, Nebraska, western New York, and Lexington, South Carolina. The slowest Spectrum speed we’ve seen come through our test is about 36 Mbps, while the fastest hit 82 Mbps. That’s not to say Spectrum can’t get faster than that—we just haven’t had any Spectrum Gig customers use our test yet.

Does Spectrum offer cable TV with no contract?

Yes, Spectrum offers no contract cable TV service. Spectrum TV packages range in price from $44.99 to $104.99 per month. Spectrum offers Double and Triple Play bundles with Internet, mobile phone plans, and home phone (landline) service.

Spectrum also offers a streaming TV service called TV Essentials for $14.99 per month. Rather than delivering content through cable boxes, TV Essentials streams live TV content to your Internet-connected device. Since there’s no setup fee, it’s easy to cancel or add service anytime.

TV Essentials has over 60 basic channels like A&E, Comedy Central, Discovery, Animal Planet, BBC America, Hallmark, and more. You can’t get premium channels like HBO® or STARZ®, but it’s a great bargain package for Spectrum Internet customers who want a little live TV to go along with their Netflix or Hulu account.

Xfinity Speed Test FAQ

Xfinity speed test results shown above are based on thousands of real-world Comcast Xfinity connections. Keep in mind that these test results are run by actual users, not technicians or IT experts — because of this, our Xfinity speed test results often include home networking issues caused by user error. This results in lower speed averages than you are likely to experience on a properly-installed Comcast Xfinity connection. To remedy this, the tables above show 90th percentile results in addition to raw Xfinity speed test averages. 90th percentile results remove the lowest tests, which are commonly the result of test error, to provide a higher average that more closely mirrors the actual experience of Xfinity connections we’ve tested.

Why Are Xfinity’s Upload and Download Speeds Different?

Xfinity is a cable Internet provider, which means that their Internet service is provided over coaxial cable networks. These copper cable networks are older than the “fiber” networks, and have limited bandwidth compared to fiber-optic technology. Even using the latest DOCSIS 3.1 transmission technology, the upload speed of Xfinity speed tests will almost always be significantly lower than the download speed.

Xfinity, like all cable Internet providers, chooses to prioritize download speeds for their customers because most users download much more content than they upload. For example, when using Netflix to stream a film, most of the transmission of data is going from Netflix’s server down to your home network. The only data going “up” will be the small requests you make while interacting with the Netflix interface, like pushing pause, selecting a film, fast forward, and etc.

Is Xfinity’s Latency Normal?

Our Xfinity speed test tool shown above includes latency measurement. Latency is how long it takes for data to make the round-trip journey from your home network to a server and back again. You can think of it as a measurement of “lag.” Latency matters most for gaming, video chat, and other real-time activities. Latency is not a major concern for regular activities like scrolling through Facebook or watching Hulu.

Xfinity speed test records we’ve analyzed show that their latency is similar to other cable providers, and is good enough for the vast majority of users. Only professional gamers are likely to have any issue with Xfinity’s latency performance.

What Speed Is Xfinity Performance Internet?

Global

Xfinity’s “Performance” Internet service performs similarly to all other Xfinity plans in terms of how the “promised” or “advertised” speed compares to the delivered speed. In general, you can expect that the speed you get on a laptop when testing your connection over WiFi will be around 10–30% below the speed of your plan. This is normal — a variety of factors slow down the speed that reaches individual devices on a healthy home network, with signal fade in WiFi being the biggest issue. When running a speed test on an Xfinity Performance Internet plan, you’ll only get 100% of the speed if you plug directly into the router with ethernet. Wired connections are much faster, and it prioritizes the wired device over other “WiFi hog” devices in your home.

Xfinity Internet Speeds in Context

Overall, Comcast speed tests are comparable to other cable providers. Since launching their DOCSIS 3.1 update, they even outperform the average in many cities. Their network quality varies from area to area, so be sure to check results in your city. Search your zip code with our search tool at the top of this page to see local speed statistics.
