slow upload speed on spectrum

If you have found that your Spectrum Internet connection’s download speed is perfect, but the upload speed is appalling, don’t worry! Many users struggle with this issue. This doesn’t mean the problem is with the “provider” or your “capacity”; there could be a handful of causes disrupting the upload speed.
Too often, the cause of slow speed is evident. You must have heard of some of them already. As mainstream as they seem, these are quick fixes for slow upload troubles. Before looking at the solutions, start with the good old speed test.

How to Perform a Spectrum Internet Speed Test?

When performing a speed test, Spectrum suggests using an Ethernet cord for connecting to your modem. This way, it’s easier to identify if the problem is with Spectrum Internet or your wireless connection. You may also try Spectrum Internet outage phone number to get instant help.

To perform an internet speed test, make sure you stop all Internet activities on the device. It’s best to close all current tabs as well. Follow these steps:

  1. Visit a reliable speed testing site such as
  2. As soon as you click the site, click on “GO.”
  3. It automatically starts processing and displays the results.
  4. You will see your current upload and download speed.

Understanding the internet Speed Test Results

Download Speed

It’s the speed at which data is delivered to your PC. It’s the most information your computer can receive from the Internet in a matter of seconds.

Upload Speed

It measures the maximum amount of information a PC can send to the Internet.
Note: If you have an Internet speed of 100 Mbps or higher, it is usually recommended to get a wired connection.

Tips to Fix Slow Upload Speed Issue

Follow these remedies to improve the upload speed on Spectrum:

1. Outdated Device

After the internet speed test, it will narrow down the source of slow speed. Make sure your PC is hardwired to the Ethernet cable to rule out the Spectrum WiFi issues.
The more powerful a device (tablet, laptop, or smartphone) is, the better your Internet will perform. If you are using an older tool, then upload as well as the download speed is likely to affect.

2. Too Many Applications

When too many apps are running on a single device, not only do they consume bandwidth, they make the device slow. As a result, the upload speed suffers.
Check all devices to make sure the apps currently running are necessary. Close the ones that are running in the background but not being used.

3. Blocked WiFi Signals

Obstruction between the router and a connected device degrades the signals. This blockage could be walls and even metal furniture. Clear all obstacles in the way. Ideally, place the router in the middle of the house or business. In other words, make it centrally located within the spot where you use the WiFi most.
Somebody should never place the router/modem in a cabinet. Keep it in an open location at a suitable height. You may also invest in a WiFi extension to boost signals.

4. Wrong Internet Plan

When you subscribe to Spectrum’s Internet services or any other ISP, choose a plan that’s right for you. The provider has three different internet tiers. The lowest level offers 100 Mbps. It’s also cheaper. The second tier provides 300 Mbps, which is for households with up to 2 or more connected devices. Then comes the highest level that delivers 940 Mbps. It’s their fiber optic plan that best suits businesses.

If you have signed up for the provider’s lowest tier and you spend lots of time uploading massive files, it may take ages to act. Our browsing habits and needs change from time to time. In case you now need more bandwidth, consider upgrading your data plan to avoid delays.

5. Limited Memory

Is your computer overloaded with thousands of saved files? If yes, this could take up your RAM and leave you with limited memory. And little RAM causes the PC and its function to slow down. This plan also includes the download and upload speed of your Internet.
To solve this problem, first, remove all unnecessary and outdated data from your hard drive. The next thing to do is segment your system. If you are not sure limited memory is causing the problem, start your PC in safe mode with networking capabilities. Run the speed test to check if your PC is the culprit.

6. Program Limitations

Specific programs impact the upload speed on the Internet connection too. These include KaZaa and LimeWire, which take a large amount of bandwidth for downloading and uploading files. Similarly, using a VoIP service can also drain the bandwidth. Some firewalls can block the bandwidth too.
Shut down or close all programs that could be sucking up the bandwidth. If it has been a while since you have used these programs, delete them. They could be limiting your speed online.

7. Browse Bottlenecks

Certain plug-n features or add-ons on the browser can eat up bandwidth too. Some browsers also have security features for scanning a web page for safety before loading it. You can disable all unnecessary add-ons by visiting the settings of your browser.
Sometimes, even after disabling the add-ons, the upload speed doesn’t improve. In that case, your browse might need an upgrade. On the other hand, if you have noticed the browser has become way too slow, and it may corrupt it. Uninstall it and upgrade to the latest version to ensure your devices are browsing at their maximum speed.

8. Host Server Hang-ups

Often, the host server which hosts a particular website is to blame, not the Internet service. Server hang-ups cause Internet speed to suffer. When a server in use is misconfigured/underpowered, then you might see such issues.
To test if the host server setting is the cause, visit different websites. If other websites are loading fine and only the location which you were experiencing trouble with is slow, that means the problem is definitely with the host.
Next time your upload speed suffers, now you know what to do before directly calling Spectrum customer support.
