Spectrum Internet Speed frequently throttling down to 30-40 MBps, paying for 1 GB.

Title: Troubleshooting Spectrum Internet Speed: A Journey Towards Resolution

Are you paying for high-speed internet but finding your connection less than satisfactory? You’re not alone. I’ve been grappling with inconsistent Spectrum Internet speeds since moving into my new home in August 2019, despite my subscription promising speeds of up to 1 Gbps.

Here’s a brief overview of my experience: on occasion, I’ve seen speeds soar to 1150 Mbps, which indicates that my connection can perform at its best. However, I frequently experience significant drops to speeds of just 30-40 Mbps throughout the day. During speed tests, I often see my connection start strong, peaking at about 700 Mbps, only to gradually decline to around 500 Mbps before the test concludes.

Despite having eight different technicians from Spectrum visit my home, the issue remains unresolved. Many of them seemed uncertain and brushed off my concerns by stating that everything was “functioning as intended.” This experience has been frustrating, to say the least.

Recently, I called Spectrum support and was informed that my modem might be exhibiting packet loss. However, my own continuous pings to Google’s DNS (8.8.8.8) show no evidence of this, adding another layer of confusion to the issue.

To clarify my setup: I’m using a Spectrum modem connected to a Spectrum WiFi router, which then feeds into a 16-port gigabit switch that powers my desktop computer, among other devices. I’ve already had my modem replaced, which temporarily resolved the speed drops, but the problem resurfaced just two weeks later. Since I’ve been traveling frequently, I haven’t had a chance to troubleshoot effectively until now.

Here are some factors to consider during my troubleshooting journey:

  • New Construction Home: Could the wiring in my house be impacting the connection? A cable tester may be necessary to investigate this further.

  • Coaxial Line to Node: I’m aware that my connection isn’t true fiber, which could affect performance.

  • Spectrum’s Equipment: It’s crucial to analyze how the provided equipment interacts with my setup.

  • Connected Devices: My home network includes an array of devices such as an Arlo security system, two smart TVs, two PS4s, three laptops, three smartphones, two desktops, and a Sonos speaker, all of which could potentially affect bandwidth.

As I look for assistance to narrow down the cause of these speed fluctuations, an update is looming. Today, at 1:

  1. Hi there,

    It sounds like you are experiencing intermittent speed fluctuations despite your equipment being relatively new and properly configured. Here are some steps and considerations that might help you troubleshoot further:

    • Check for Network Congestion: With multiple devices and heavy usage, bandwidth can be impacted. Try performing speed tests during different times of the day to identify if peak hours cause the slowdown.
    • Inspect Cabling and Connections: Since you have a new construction home, ensure all coaxial and Ethernet cables are high quality and securely connected. A cable tester can definitely help identify any wiring issues or signal attenuation.
    • Monitor Modem and Router Logs: Access your device logs to look for errors or warnings related to packet loss, disconnects, or signal issues. Sometimes, firmware updates are needed for optimal performance.
    • Optimize Network Topology: Consider placing your router in a central location, minimizing interference, and updating firmware. You may also want to temporarily disconnect some devices to see if bandwidth improves.
    • Spectrum Support: Since they’ve mentioned potential packet loss, request detailed diagnostic tests such as documentable signal levels, SNR, and downstream/upstream power levels. Persistently high or low levels could hint at wiring or infrastructure issues on their end.
    • Bandwidth Management: Use Quality of
