How to measure speed before choosing an ISP plan

You are comparing internet plans, but the speed listed on each offer may not match what you get at home. A single speed test can also be misleading if Wi-Fi, other devices, or busy evening traffic affect the result.

Measure your connection under a few conditions before you choose. The Speed Test reports download speed, upload speed, ping, and jitter in your browser. These results help you spot when your current connection is limited, and whether the issue may be Wi-Fi rather than your ISP plan.

Measure your current connection

1. Open the Speed Test and run it once. Note the download and upload speeds, ping, and jitter.
2. Write down the date, time, device, and connection type. Record whether you used Wi-Fi or an Ethernet cable, and whether anyone else was using the internet.
3. If you can, connect a computer to the router with Ethernet and test again. This gives you a useful comparison with Wi-Fi. If you do not have an Ethernet cable, test near the router first, then in the room where you normally use the internet.
4. Repeat the test at different times, such as morning, afternoon, and evening. Try this on at least two or three days, including a time when your household is normally online.
5. Run one test when the connection is quiet and another during your usual busy period. Keep the same device, browser, and location where possible, so the comparison is fair.

Speed tests exchange test data with our server to measure your connection. If your internet plan has a data limit, keep in mind that testing uses some of that data. For a closer look at how results change through the day, see how to test your internet speed at different times.

What the results mean

Download speed is low in every test

Download speed affects activities such as loading websites, streaming, and downloading files. If it is consistently low on Ethernet as well as Wi-Fi, and no other device is using much bandwidth, your plan, modem, router, or ISP connection could be limiting the result. Compare your readings with the speed your plan advertises, but remember that an advertised speed is not always a guaranteed speed at every moment.

Ethernet is fast, but Wi-Fi is slow

Your internet connection may be working well, while the wireless link between your device and router is the weak point. Distance, walls, interference, and the device's Wi-Fi hardware can all affect the result. Upgrading to a faster ISP plan may not improve the speed in that room.

Speed drops during busy hours

If wired results are reliably lower in the evening than at quiet times, the connection or network may be congested. If the drop happens only when people at home are streaming, uploading, or downloading, the household may be using most of the available capacity. One test cannot identify which cause applies, so compare readings across days and conditions.

Ping or jitter is high, even when speed looks good

Ping is the time it takes for a request to get a response, measured in milliseconds. Jitter is variation in that response time. High or uneven readings can affect video calls and online games, but they do not directly tell you how many megabits per second your plan needs. If the readings rise only during downloads or uploads, the connection may be getting delayed when busy.

Get a fairer reading before changing plans

1. Pause large transfers. Stop file downloads, cloud backups, and app updates for a quiet baseline test. Then run a separate test during normal household use to see how the connection behaves when busy.
2. Check the connection type. Test with Ethernet if possible. On Windows 11, see Settings › Network & internet to check whether the computer is using Wi-Fi or Ethernet. On a Mac, open System Settings › Network and check the active connection.
3. Move closer to the router. Test in the same room as the router, with as few walls and large objects between you as possible. If that reading improves, test again in your usual spot to see how much the room affects your connection.
4. Restart the router and modem. If results are unusually poor across devices, restart the network equipment, wait for it to reconnect, and run another test. Do not reset it to factory settings unless your ISP tells you to.
5. Compare another device. Test a second computer or phone in the same place. If only one device is slow, check its Wi-Fi connection or network settings before blaming the plan.
6. Contact your ISP with the readings. Share the test times, connection type, and results, especially if wired speeds are consistently far below the plan's stated rate. Ask whether there is an outage, a line issue, or a modem limitation.

Choose an ISP plan from the results

A speed test shows how much capacity was available during that test. It does not show how much bandwidth your household actually needs, or how much each activity uses. If your current connection is fast enough for the things you do, a higher plan may not make a noticeable difference.

Think about the busiest time you expect to use the internet. Count activities that happen at once, such as several video streams, a video call, and a large upload. Choose a plan that can handle that combined demand with some room to spare. As a simple planning example, if you estimate that simultaneous use needs about 160 Mbps, a plan around 200 Mbps leaves roughly 25 percent extra capacity. That is a planning margin, not a promise that every device will always reach that speed.

Check upload speed separately if you send large files, back up photos, livestream, or make frequent video calls. Some plans have much lower upload speeds than download speeds. Also check the provider's terms for advertised versus typical speeds, equipment fees, data limits, and how long a promotional price lasts.

Use repeated wired readings to judge the connection reaching your home, and Wi-Fi readings to judge coverage where you use your devices.
