What Does Spectrum Internet Troubleshooting Mean?

What is troubleshooting? Simply put, troubleshooting is identifying why something isn't functioning properly and suggesting ways to improve it.

Thus, Spectrum Internet troubleshooting means figuring out why Spectrum's network is sluggish, unstable, or unable to connect, among other issues, and resolving these problems.

Troubleshooting Spectrum Internet

Now, let's begin troubleshooting Spectrum Internet problems.

Why is Spectrum Internet Performance Poor?

Many factors can influence network performance, including hardware and software factors. Hardware factors involve the quality of devices like wires/cables and WiFi routers. Software factors include the quantity, properties, and types (functional, communicational, entertaining, etc.) of programs.

Here is a list of common causes that significantly impact Spectrum network performance.

• Power outage
• System memory (RAM)
• File-sharing Programs: File-sharing programs, such as BitTorrent, consume a large amount of data during their processes, leading to slow network speed.
• Firewalls: Firewall software monitors all network traffic on your PC. A strict firewall can result in slow connection speed.
• Viruses/malware/spyware/adware/ransomware/trojan/hijacker...

How to Make Spectrum Internet Faster?

After troubleshooting Spectrum Internet, you know the reasons for poor network performance like slow speed. Then, what are the solutions?

Method 1. Close Idle Programs

If you experience low Internet speed while opening many applications, then, it is those programs that share your bandwidth and slow down the network speed of your computer. Thus, close the software you do not use currently.

Method 2. Upgrade RAM

The random-access memory (RAM) is a core processing unit within a PC. If it is old or small, even if you have a good bandwidth, your machine cannot make full use of the Internet. Therefore, upgrading your old or small RAM will also improve the performance of your Spectrum Internet.

Method 3. Avoid Using File-Sharing Programs While Doing Other Business

As described earlier, file-sharing software will take a large amount of data. So, if it is not urgent, you can use it when you do not have other business to do on the computer. Otherwise, you have to spend more time on your business while also getting slow progress on the file-sharing program, leaving both tasks unfinished even after a long time.

Instead, if you do the two tasks one by one, it may cost you less time together compared with the time taken by doing the two tasks simultaneously.

Method 4. Reset Firewall to Default Settings

As mentioned in the above Spectrum Internet troubleshooting, firewall software will slow down your Internet speed. However, you do need at least one firewall program to ensure your network security. So, the compromise is to set the firewall to default settings. Below is an example of resetting Windows 10/11 firewall.

Step 1. Click Start in the bottom left and select Settings.

Step 2. Choose Update and Security.

Step 3. Click Open Windows Security on the top.

Step 4. In the new window, select Firewall and network protection on the left panel.

Step 5. Click Restore firewalls to default.

Then, follow the guidance to finish the task.

Method 5. Check for Harmful Software

Sometimes, when you are attacked by viruses, you will also experience a slow Internet speed for the viruses will also use your network to carry out their attacks. Then, you need to rely on an anti-virus program, such as Windows Defender, to find and eliminate the viruses.

Method 6. Keep Your Programs Up-to-date

Old hardware, such as RAM mentioned above, will consume much data. Similarly, old or outdated software will also occupy much bandwidth. New refined programs use fewer Internet data compared with their old versions. Thus, updating your old programs is also a way to speed up your machine.

Method 7. Ensure Your System Meets the Minimum Requirements

The following minimum requirements are for Windows operating systems (OS).

1. OS: Windows 8 or later

2. Network capability:

• 1 Gbps (1,000 Mbps) full-duplex Network Interface Card (NIC)
• An 802.11 AC router for speeds higher than 300 Mbps
• An 802.11 N router for WiFi speeds up to 300 Mbps

Method 8. Restart Computer or Device

Restarting your computer or devices will refresh them and improve the Internet performance as known through Spectrum Internet troubleshooting. Particularly for PC restart, it will close all running programs and services. So, the reconnection of the network will give you a faster speed as well as address other internet problems like inability to connect.

Method 9. Upgrade Spectrum Internet Speed

Speeds vary depending on location and package. You can try to find out whether you are eligible to upgrade your network speed or not.

Of course, you can test your speed before upgrading it. There are two ways; one is using a wired device like a computer connected to the modem with a Cat 5e or higher Ethernet cable; while the other is to download an app to test internet speed via wireless data.
