Why Is My Internet Slow? How to Do a Proper Speed Test

Slow internet is one of the most common tech frustrations, and it's not always your provider's fault. Before assuming you're paying for speeds you're not getting, it helps to run a proper internet speed test and understand what the numbers actually mean.

This guide walks through how to test correctly using the Internet Speed Test and Network Latency Test, plus common fixes.

What Speed Test Numbers Actually Mean

• Download speed: How fast data transfers from the internet to your device, relevant for streaming, downloading, and browsing.
• Upload speed: How fast data transfers from your device to the internet, important for video calls and uploading files.
• Latency (ping): The delay between sending a request and receiving a response, critical for gaming and real-time communication.
• Jitter: Variation in latency over time, which can cause choppy video calls even when average speed looks fine.

How to Run an Accurate Speed Test

1. Close other applications and browser tabs that might be using bandwidth in the background.
2. Open the Internet Speed Test and run the test.
3. Review your download and upload results alongside the reported latency.
4. Run the Network Latency Test separately for a closer look at connection responsiveness.
5. Test at different times of day, since speeds can vary during peak usage hours in your area.
6. If possible, test with a wired connection and compare against Wi-Fi to isolate the source of any slowdown.

This can help determine whether slow internet is a genuine bandwidth issue from your provider, a local Wi-Fi problem, or something specific to one device or application.

Common Causes of Slow Internet

• Too many connected devices: Streaming, gaming, and downloads happening simultaneously across multiple devices can strain your available bandwidth.
• Wi-Fi signal interference: Distance from your router, walls, and interference from other electronics can significantly reduce wireless speeds.
• Outdated router firmware: Routers that haven't been updated can perform below their capability or have unresolved bugs.
• ISP throttling or network congestion: Some providers slow certain types of traffic during peak hours or after exceeding a data threshold.
• Malware or background updates: Unexpected background processes can consume bandwidth without your awareness.

Step-by-Step Fixes for Slow Internet

Fix 1: Restart Your Router and Modem

1. Unplug both devices for about 30 seconds.
2. Plug the modem back in first and wait for it to fully reconnect.
3. Plug the router back in and wait for it to establish a connection.
4. Retest speeds after everything reconnects.

Fix 2: Switch to a Wired Connection to Compare

1. Connect your device directly to the router using an ethernet cable.
2. Run the speed test again and compare it to your Wi-Fi results.
3. A significant improvement points toward a Wi-Fi signal issue rather than an overall bandwidth problem.

Fix 3: Check for Bandwidth-Heavy Background Activity

1. Check other devices on your network for active downloads, streaming, or backups.
2. Pause unnecessary downloads or updates during important tasks like video calls.
3. Retest after reducing simultaneous usage.

Fix 4: Update Router Firmware

1. Access your router's admin panel, typically through a web browser using its local IP address.
2. Check for and install any available firmware updates.
3. Restart the router after updating and retest.

Fix 5: Contact Your ISP With Test Results

1. Run multiple tests at different times of day and note the results.
2. Compare your results against the speed you're actually paying for in your plan.
3. If results consistently fall well below your plan's advertised speed, contact your provider with this data.

Wi-Fi Issue or Provider Problem?

When to Escalate to Your Internet Provider

If you've restarted your equipment, tested with a wired connection, ruled out background bandwidth usage, and updated your router firmware, but speeds still consistently fall well below what you're paying for, it's reasonable to contact your provider with documented test results from multiple times of day.

FAQ

Why is my speed test result different every time I run it?
Internet speed can vary based on network congestion, time of day, and what else is happening on your network at that moment, so some variation between tests is normal.

Does Wi-Fi always test slower than a wired connection?
Not always, but wired connections are generally more consistent and can reach higher speeds than Wi-Fi, especially at a distance from the router or through walls.

What's a good latency number for gaming?
Lower is better, with under 30 milliseconds generally considered excellent and under 60 milliseconds usually acceptable for most online games.

Can too many smart home devices slow down my internet?
Yes, a large number of connected devices can add up in bandwidth usage and Wi-Fi network congestion, even if each device individually uses little data.

Should I test speed at multiple times of day?
Yes, testing during both peak and off-peak hours gives a more complete picture of your actual real-world internet performance.

Conclusion

Slow internet often comes down to Wi-Fi interference, too many devices competing for bandwidth, or outdated router settings, rather than always being your provider's fault. Testing properly, and comparing wired versus wireless results, gives you the real picture before deciding what to fix or who to contact.
