How to Change Your Speedtest Server and Improve Test Accuracy

Changing the Speedtest server can help explain unusual download, upload, or latency results, but it does not directly increase your broadband capacity. This guide explains how server selection works, why the default server may be unsuitable, how to compare results across nearby servers, and how to separate ISP, router, Wi-Fi, modem, and server-side problems. It also provides practical steps for choosing a reliable test location and interpreting differences between fiber, cable broadband, and other connections.

Why the Speedtest Server Matters

A speed test measures the connection between your device and a selected testing server. The result reflects more than your ISP plan: it also includes the network path, server workload, routing conditions, distance, and local Wi-Fi performance. Changing the server can therefore produce different download, upload, and latency values without changing your actual broadband service.

The default server is usually selected automatically based on location and estimated network performance. In many cases, it is a reasonable choice. However, a different server may provide a more stable comparison when the default result looks unusually low or inconsistent.

How to Change the Speedtest Server

Open the Speedtest website or app and wait for the main test screen to load. Select the server name or the option that displays the current test server, then search for a city, region, provider, or server name. Choose a nearby server and start the test again.

  1. Run the test once with the automatically selected server.
  2. Open the server selection menu.
  3. Choose two or three nearby servers from different networks when possible.
  4. Repeat each test under similar conditions.
  5. Compare the median download, upload, and latency results rather than relying on one reading.

Server names and controls may differ between the website, desktop application, and mobile application. If the selection menu is unavailable, update the app, use the web version, or check whether the platform is enforcing automatic server selection.

Common Reasons to Change the Test Server

The Default Server Is Too Far Away

A distant server adds physical distance and more network hops to the test. This can increase latency and may reduce throughput, especially on connections with inefficient international or long-distance routing. A nearby server is usually more suitable for checking the performance of your local ISP connection.

The Server Has High Demand

A popular test server can become busy during peak hours. Server-side congestion may limit the measured speed even when your modem, router, and broadband line are working normally. Comparing the same connection with several nearby servers helps identify whether the limitation is specific to one server.

Your ISP Uses a Different Network Path

Internet traffic does not always take the shortest geographic route. An ISP may peer efficiently with one test provider but use a congested or indirect path to another. If results vary widely by server, the difference may indicate routing or peering conditions rather than a fault inside your home.

The Selected Server Is Not Suitable for the Test Goal

A local server is useful for estimating access-network performance, while a remote server can show how your connection performs across a longer route. Testing a server in another region may be appropriate for a specific application, but it should not be used as the only reference for judging your local broadband plan.

Wi-Fi Conditions Are Affecting the Result

Changing servers may appear to fix a speed problem when the real cause is weak Wi-Fi signal, interference, device distance, or a busy wireless channel. If results remain low across multiple nearby servers, test with an Ethernet connection or move closer to the router before drawing conclusions.

The Modem, Router, or Device Is Limiting Performance

Older network equipment, outdated firmware, overloaded routers, background downloads, VPNs, security software, or limited device hardware can reduce measured speed. A new server cannot remove these limits. Testing with one wired device and minimal background traffic makes the result easier to interpret.

How to Tell Whether the Server Is the Problem

First, repeat the test several times using the same server. Large changes between consecutive tests suggest temporary congestion, Wi-Fi variation, or other local activity. Next, test at least two nearby servers. If one server is consistently slower while the others are similar, that server or its route may be the limiting factor.

  • One slow server, several normal servers: the issue is likely server load or routing to that server.
  • All nearby servers are slow: investigate Wi-Fi, the router, modem, device, or ISP connection.
  • Download is low but upload is normal: check downstream congestion, device activity, and the ISP access path.
  • Upload is low but download is normal: check upstream network conditions, Wi-Fi interference, and local uploads.
  • Latency is high on every server: investigate distance, routing, bufferbloat, or network congestion.

Run tests at different times, such as morning and evening, and record the server, connection type, device, and results. This creates a useful pattern for support discussions with your ISP.

Ways to Improve Speedtest Accuracy

  1. Use an Ethernet cable when checking the broadband line itself.
  2. Pause cloud backups, streaming, downloads, and software updates.
  3. Disconnect unnecessary devices from the network.
  4. Restart the modem and router only when appropriate, then wait for the connection to stabilize.
  5. Use a current browser or updated Speedtest application.
  6. Disable a VPN temporarily if you are measuring the direct ISP connection.
  7. Test with a nearby server and compare it with one or two alternatives.
  8. Repeat the test at different times to detect peak-hour congestion.

Do not select a server simply because it reports the highest number. A reliable result should be repeatable and relevant to your goal. For diagnosing an ISP connection, a nearby, stable server is generally more informative than an unusually fast result from a server with a favorable but atypical route.

When to Contact Your ISP

Contact your ISP when wired tests remain well below the expected service range across several nearby servers and at different times. Provide the test dates, server names, download and upload results, latency, connection method, and whether the issue affects multiple devices.

Ask the provider to check signal levels, line errors, local congestion, routing, and any service-area incidents. If only one Speedtest server performs poorly while other servers are stable, report the pattern rather than describing the issue as a general speed failure. You can also use the Speedtest website to compare server results, but remember that changing servers measures a different network path; it does not change your subscribed broadband capacity.
