What it does

Speed Test measures the actual throughput and latency of your internet connection by transferring data between your browser and a nearby test server. It reports download speed, upload speed, latency (ping), and jitter, giving you a real-world snapshot of whether your connection is meeting the performance you're paying for and whether it can support latency-sensitive workloads like video calls, gaming, and remote desktop. To see which IP and ISP your traffic is leaving from, use What is My IP; to inspect any IP's network owner and ASN, use IP Lookup.

When to use it

Verifying that your ISP is delivering close to the advertised plan speed before raising a support ticket.
Comparing wired and Wi-Fi performance from the same device to determine whether your router or the ISP link is the bottleneck.
Diagnosing why a video call is freezing — high jitter or packet loss matters more than raw bandwidth for real-time media.
Testing a new router, mesh node, or ISP upgrade to confirm the change actually improved throughput.
Establishing a baseline before reporting recurring slowness, so you have data points across times of day. If a specific site is the slow target, check its HTTP headers for redirect chains and DNS Checker for resolver lag.

How to read the results

Download speed is what you'll observe loading sites and streaming. Upload speed matters for video calls, cloud backups, and any service where your device is the source. Latency (ping) is the round-trip time to the test server in milliseconds — under 30 ms is excellent for gaming, 30 to 80 ms is fine for most uses, and over 150 ms will be felt in interactive applications. Jitter is the variation in latency between packets; high jitter (over 30 ms) causes audio dropouts even when bandwidth is plentiful. Speeds within 80 to 90 percent of your plan, measured wired, are normal.

Common mistakes

Running the test over Wi-Fi and concluding the ISP is at fault when the bottleneck is actually wireless interference or distance from the access point.
Comparing results to your plan's "up to" speed and expecting an exact match; ISPs advertise peak rates, not guaranteed minimums.
Testing while other devices on the network are streaming, downloading, or backing up, which divides the available bandwidth.
Ignoring latency and jitter when troubleshooting calls or gaming — bandwidth alone doesn't determine real-time quality.

Frequently asked questions

What is a good internet speed?

For typical home use, 25 Mbps download is enough for streaming HD video on a few devices. 100 Mbps is comfortable for 4K streaming, video calls, and gaming. Beyond 300 Mbps the bottleneck is usually elsewhere (Wi-Fi, the source server, or the device).

What is the difference between download and upload speed?

Download speed is how fast data arrives from the internet to your device — it matters for streaming, browsing, and downloads. Upload speed is how fast data leaves your device — it matters for video calls, cloud backups, and live streaming.

What is ping (latency)?

Ping (or latency) is the round-trip time for a small packet, measured in milliseconds. Lower is better. Under 50 ms feels instant; 50-100 ms is fine for most use; over 150 ms is noticeable in gaming and video calls.
