Why Is Download/Upload Speed Slow On Spectrum?

Bad weather is the most common reason why the Spectrum is so slow on your system. Thus, check out the weather in your area. But, if that’s not the issue, you may go through the reasons mentioned here: 

  • Network capacity crunch: Spectrum has a limited network capacity. Consequently, the internet speed may slow down when the demand is high. Hence, the spectrum internet download speed may slow down considering the number of users in your area. 
  • Network Throttling: Spectrum offers users a fantastic “always-on” connection feature. That means the Spectrum remains active 24 hours a day. However, this may throttle (slow down) your internet speed if you stream heavy data or download large files. 
  • Spectrum hardware: Spectrum uses Motorola SurfBoard cable modems for its string signals. It can therefore manage the internet for all of your household gadgets. But if it’s handling multiple devices, it can also slow down the performance.
  • Software update: You need to stay aware of its latest update, which may roll out for security or privacy reasons. Thus If you wonder- why has the spectrum internet been so slow? Check the software updates.

Here’s How to Troubleshoot Why Spectrum Is So Slow?

Several factors may influence your internet speed and internet connection. This, in turn, can affect your upload and download speeds. So, to find the cause and resolve the issue, let’s troubleshoot using these methods. 

Fix 1: Restart Your Modem and Router

Restarting the device is the leading solution for technical issues. It’s easy and quick. Thus, anyone can perform the steps without requiring any technical knowledge. 

  • Press the turn-off button on your device.
  • Unplug the modem/gateway cable from the power outlet.
  • Wait for one minute.
  • Plugin in the back of the power cable.
  • Press the power button to restart the device. It may take some time.
  • Restart your computer/laptop also. 

Note: You can use the same steps for your standalone router. 

Fix 2: Verify Your Cables

Your spectrum setup has a coaxial cable to connect to the modem or gateway. Ensure the cable is connected correctly, is not damaged, and fits the coaxial wall outlet.

If you still get the issue, you should check for damage. Usually, when the cable is twisted or stretched to its capacity, it gets torn and kinked. Hence, you may have to replace it. 

Fix 3: Use Ethernet Cable

Undoubtedly, the Ethernet cable connection is far more secure than anything. One primary reason why people opt for Ethernet over a wireless connection.

But, it also has some limitations. It cannot be used for more than one device at a time. It is not feasible for a home network where you have multiple devices. Thus, it can be a temporary solution. 

Pull out the cable packs with the router to use the Ethernet on your system. Plug one end into the spectrum router’s Ethernet port and the other into your device. Wait until it establishes the connection. Once it’s done, you can enjoy the flawless speed.
