Is Your Spectrum Wi-Fi Slow? Here’s How to Troubleshoot it

A broadband technician’s pro tips to solving Spectrum Internet issues.

The trick to fixing your Spectrum Internet problems fast is to start with the most likely causes. As a prior broadband technician, I solved internet problems on over 1,000 home networks, and I know how easy it is to become overwhelmed by the heaps of possible causes. Some Spectrum Internet issues tend to pop up more often than others, and that’s where we’ll start so you can get back online as quickly as possible.

Slow internet?

If your plan doesn’t provide enough bandwidth, your internet may seem slow and sluggish, even if nothing is technically wrong with your internet service. Use our How much internet speed do I need? tool to find out if you need a faster internet plan.

Begin by restarting your modem and router

This is the go-to solution of every IT pro simply because it works so often, and it’s quick and easy. You may have a modem and separate router or a combo modem/router unit called a gateway. Whatever your setup, the restart process is the same.

Restart your equipment using your Spectrum account

Step 1: Sign in to your Spectrum account.

Step 2: Choose the Your Services tab and then choose the Internet sub-tab.

Step 3: Select your equipment from the list.

Step 4: Select Restart equipment and confirm.

Restart your equipment using the Spectrum App

Step 1: Tap the Services icon.

Step 2: Select Internet.

Step 3: Select your equipment from the list.

Step 4: Choose Restart Equipment.

Step 5: Hit the Restart button.

Restart your equipment manually

Step 1: Power down your connected device.

Step 2: Unplug the modem or gateway power cable.

Step 3: Wait 60 seconds.

Step 4: Plug the power cable back in.

Step 5: Wait for your modem or gateway to restart. This may take several minutes.

Step 6: If you have a separate, standalone router, restart it using steps 1–5.

Step 7: Restart your connected device.

Check your cables

Make sure all your cables are properly connected and undamaged, starting with the mainline into your home. Your Spectrum Internet signal comes through a coaxial cable (the same type of cable used for cable TV) connected to the back of your modem or gateway. Ensure the coaxial cable is screwed snuggly to the modem and to the coaxial wall outlet.

Next, check your Ethernet cables. If you have a separate modem and router, there will be an Ethernet cable connecting the two. The cable should click when inserted into the Ethernet ports on the modem and router.

Lastly, check for damage like tears and kinks in the cables. Cables are often damaged by harsh twisting, stretching, and tension. Also, check for chew marks if you have a pet.

Connect using an Ethernet cable

Connecting your computer directly to your router or gateway using an Ethernet cable bypasses your Wi-Fi network, ruling out an issue with your Wi-Fi. To do this, you’ll need an Ethernet cable and a computer with an Ethernet port. Plug the cable into an outport on your router or gateway (usually colored yellow) and plug the other end into the Ethernet port on your computer.

If your internet improves with a wired connection, you likely have an issue with your Wi-Fi. You could also run a speed test using Wi-Fi and then again over Ethernet and compare the results to confirm.

Check your internet speed

A speed test can tell you if you’re actually getting the speeds advertised by your internet plan. Use our internet speed test to find out. We recommend running the speed test over a wired Ethernet connection, as most ISPs guarantee plan speeds only over a wired connection.

Try a different device

Your internet issue could be with the device you’re using rather than your Spectrum Internet connection. Try accessing the web on a different computer, phone, or tablet—if it works, you know there’s an issue with your device.

Try a different website

Along the same line of thinking, the website you’re trying to access could be down. Try loading a different website. If it loads, chances are your internet is fine, and the original website you tried to visit is just experiencing issues.

Clear your browser cache

Your browser stores information from the websites you visit in what’s called a cache. This is so your browser can load the websites faster on your next visit. But sometimes, pesky data and glitches sneak into the cache and cause problems. Your browser has a function that will clear out the cache, refreshing your browser with a clean slate.

Instructions for clearing your cache:

Clear the cache in Google Chrome1

Step 1: Open Chrome and open the More menu by clicking the three vertical dots in the upper-right corner.

Step 2: Select More Tools.

Step 3: Select Clear Browsing Data.

Step 4: Check the boxes next to “Cookies and other site data” and “Cached images and files.”

Step 5: Select “Clear data.”

Clear the cache in Safari (on Mac OS)2

Step 1: Open Safari and click Safari in the top menu bar.

Step 2: Select Preferences.

Step 3: Select the Privacy tab and click Manage Website Data under Cookies and Website Data.

Step 4: Click Remove All.

Clear the cache in Microsoft Edge3

Step 1: Open Edge and open the menu by clicking the three dots in the upper-right corner.

Step 2: Select Settings, and navigate to the Security and Privacy section using the menu on the left.

Step 3: Click “Clear browsing data.”

Step 4: Check the boxes labeled “Cookies and other site data” and “Cached images and files.”

Step 5: Click the “Clear data” button.

Scan for viruses and malware

Viruses and malware can have tremendously negative effects on your home network. Spectrum actually provides a tailor-made security solution for its customers called Security Suite. You can download Security Suite from the Spectrum website.

Turn off your antivirus firewall

Your antivirus software is vital for keeping your network safe from viruses and malware. However, sometimes it can interfere with your internet connection. If you’re running out of options, try turning off your antivirus firewall briefly, just to see if it fixes the problem.

If it does, we recommend you turn it back on and either work with your antivirus software provider to fix the issue permanently or replace your antivirus software immediately. You really don’t want to put yourself at risk by surfing the web unprotected.

Check for a service outage

Unfortunately, service outages do happen, and Spectrum has several ways you can check. You can use the Spectrum app or your online account to set notification alerts for outages. You could also use Spectrum’s chat feature on its website or call to ask if there’s an outage in your area.
