Fiber Internet speed test: How to tell if your connection can keep up

Wondering if your Internet is actually delivering what you're paying for? Here's how to run a fiber Internet speed test, read the results, and know when something's off.


If your connection feels slow but you can't quite put your finger on why, a speed test is the fastest way to get a concrete answer. It takes about 30 seconds and tells you a lot.

How to run one

Start at Ting's speed test. For the most accurate results, run it from a device that's plugged directly into your router via ethernet, Wi-Fi adds variables. That's because a Wi-Fi signal has to travel through walls, compete with other devices, and deal with interference from neighboring networks. The speed you see over Wi-Fi often reflects your wireless environment as much as your actual Internet connection, so ethernet gives you the cleaner read.

What the numbers mean

A speed test fiber result gives you three things to pay attention to: download speed, upload speed, and ping.

Download speed is how fast data comes to you, streaming, loading pages, pulling files from the cloud. Upload speed is how fast data leaves, video calls, file sharing, sending large attachments. Ping is the response time between your device and the server, measured in milliseconds.

For a solid remote workday, you generally want at least 25 Mbps download and 10 Mbps upload per person actively working. For video calls specifically, most platforms recommend at least 3–5 Mbps upload per stream. Ping under 20ms is excellent; anything over 100ms and you'll likely notice lag on calls or in real-time applications.

On a fiber connection, upload and download speeds should be close to equal. That symmetry is one of fiber's defining advantages over cable.

When to call your ISP

If your speedtest fiber results consistently come in well below what you're paying for, not just during a one-off busy moment, but repeatedly across different times of day, that's worth a conversation with your provider. A good ISP will take that seriously. At Ting, real humans answer when you call.
