How to Use an Internet Speed Test to Improve Your Connection

Your internet connection isn’t performing the way it should, and everything from work meetings to weekend Netflix binges is suffering. Before you pick up the phone to call your ISP or run to reset your modem, the best place to start is with an internet speed test. But it’s not just about checking numbers. Understanding how to interpret the results and what actions to take can make all the difference.

What Is an Internet Speed Test?

An internet speed test is a tool that measures how fast data travels from your device to the internet and back. It typically evaluates three core components:

• Download speed: How fast your device receives data from the internet.
• Upload speed: How fast your device sends data to the internet.
• Ping (latency): The time it takes for a signal to go from your device to a server and back.

These metrics help you determine whether you’re getting the internet performance you’re paying for and whether your setup supports your online activities, like streaming, gaming, video calls, or working from home.

Why You Should Run an Internet Speed Test

Running an internet speed test isn’t just about satisfying curiosity. It helps you:

• Troubleshoot slow connections
• Verify your internet provider’s advertised speed
• Optimize Wi-Fi setup or router placement
• Improve streaming or gaming quality
• Identify bandwidth hogs on your network

Without concrete numbers, you’re just guessing at the root of your internet problems. Speed tests give you data to make informed decisions.

How to Run an Internet Speed Test Properly

To get accurate and actionable results from your internet speed test, follow these steps:

Step 1: Choose a Reliable Speed Test Tool

Here are some of the most trusted tools:

• Speedtest by Ookla
• Fast.com by Netflix
• Google Speed Test
• Xfinity Speed Test
• AT&T Speed Test

Choose a tool that allows you to see download/upload speeds, ping, and even jitter if possible.

Step 2: Prepare Your Device

• Close all background applications using bandwidth (streaming apps, cloud sync, torrents).
• Disconnect other devices from your network temporarily.
• Use a wired connection (Ethernet) if possible for the most accurate results.

Step 3: Run the Test at Different Times

• Test during peak and off-peak hours (morning, evening, late night).
• Compare Wi-Fi vs. Ethernet speeds.
• Run multiple tests to calculate an average speed.

How to Read Internet Speed Test Results

Once your test is done, you’ll get a summary that includes:

1. Download Speed (Mbps)

This shows how quickly you can stream videos, load websites, and download files. The higher, the better.

• 5 Mbps: Minimum for basic streaming
• 15-25 Mbps: Good for HD video streaming
• 50+ Mbps: Ideal for multiple users and 4K content

2. Upload Speed (Mbps)

Important for sending emails with attachments, uploading videos, and video conferencing.

• 3 Mbps: Basic video calls
• 10 Mbps+: Smooth video conferencing and file uploads

3. Ping (Latency)

Measured in milliseconds (ms), this is critical for gaming, video calls, and real-time applications.

• Under 20ms: Excellent
• 20-50ms: Good
• Over 100ms: Poor (lags and delays)

4. Jitter

Jitter measures the variability in ping. High jitter causes stuttering in video/audio calls.

• Under 30ms: Acceptable
• Over 50ms: May cause problems

What to Do If Your Internet Speed Is Slow

1. Compare Against Your ISP Plan

First, check what speed your ISP promises. If you’re supposed to get 200 Mbps download and you’re only seeing 50 Mbps, something’s wrong.

2. Reboot Your Modem and Router

Turn off your modem and router, wait 30 seconds, and turn them back on. This clears temporary glitches.

3. Check for Interference and Distance

Wi-Fi signals weaken with distance and physical barriers like walls and floors.

• Place your router centrally
• Avoid placing it near microwaves, cordless phones, and other electronics

4. Update Your Equipment

Old routers or modems may not support high-speed internet. Upgrade to a modern router with dual-band or tri-band support.

5. Limit Bandwidth-Heavy Applications

Multiple people streaming or downloading large files can drain bandwidth.

• Schedule downloads during off-peak hours
• Use Quality of Service (QoS) settings to prioritize important traffic

Advanced Tips to Improve Internet Speed Based on Test Results

1. Use a Mesh Wi-Fi System

Mesh systems like Google Nest, Eero, and Netgear Orbi extend coverage throughout large homes and eliminate dead zones.

2. Change DNS Settings

Switching to a faster DNS server like Google (8.8.8.8) or Cloudflare (1.1.1.1) can improve loading speeds for websites.

3. Install Wi-Fi Extenders or Powerline Adapters

Wi-Fi extenders help spread your network further. Powerline adapters use your home’s electrical wiring to extend your internet.

4. Scan for Malware

Viruses and malware can slow down internet performance. Regularly scan your devices using antivirus software.

5. Use Ethernet for Critical Devices

For tasks like gaming or Zoom meetings, connect directly with an Ethernet cable.

How Often Should You Run an Internet Speed Test?

• Weekly or monthly to monitor performance trends
• After setting up new equipment or switching ISPs
• When you notice slowdowns or buffering

Consistent testing helps you identify when things go wrong and builds a history you can reference when talking to your provider.

When to Contact Your ISP

If your internet speed test results are consistently below what your ISP advertises:

• Take screenshots of your results over several days
• Document times and dates of tests
• Call your ISP with evidence and request a resolution

In some cases, they may offer a better plan, troubleshoot remotely, or send a technician.
