Assessing your internet speed is an astute method to verify that you are receiving the service for which you have contracted. However, if the findings are slower than anticipated, refrain from hastily attributing blame to your ISP—testing errors may be distorting your data.
Simultaneous Operation of Additional Applications or Devices
A prevalent error when assessing internet speed is neglecting to close other applications or devices operating in the background. Background applications may interfere with the results, as bandwidth will be allocated between the speed test and the other applications.
The magnitude of the impact will fluctuate based on the actions conducted by other applications; nevertheless, for bandwidth-intensive tasks such as streaming, downloading, or backing up content, the outcomes can be considerably influenced.

The same is true for gadgets linked to your internet. When numerous devices are linked to the network, they collectively share the entire bandwidth. Consequently, conducting a speed test will not accurately represent your total available bandwidth. Instead, it will display the velocity of the residual bandwidth accessible to your device at that moment, subsequent to the allocation to other devices.
To obtain an accurate measurement, terminate all extraneous applications and browser tabs before to commencing the test. Furthermore, briefly detach additional devices from the network.
Testing using Wi-Fi In lieu of Ethernet
Testing using Wi-Fi is advantageous and an effective method to assess your current internet speed. However, if you seek the most precise assessment of your network speeds, this is not the optimal choice. Conducting your test over Wi-Fi introduces numerous variables that can skew the findings.
The distance from the router, obstructions such as walls, interference from other devices, and the router's positioning can all influence your Wi-Fi performance. Conducting a speed test from your bedroom while the router is situated in the living room may yield results that are inferior to the actual potential of your connection.
For optimal accuracy, establish a direct connection via Ethernet. If you lack an Ethernet cable, Ugreen's 6-Foot Cat8 Ethernet cable and DbillionDa Cat8 Ethernet cable are cost-effective options that provide high-speed performance. Given the benefits, one should prioritize utilizing Ethernet over Wi-Fi whenever feasible.
If Ethernet is unavailable, attempt testing in proximity to the router to reduce physical obstructions, such as walls, and interference from other devices. Nonetheless, it is important to note that Wi-Fi speeds will invariably be inferior than those of a conventional Ethernet connection, even in optimal circumstances.
3. Testing Conducted Solely Once
Dependence on a solitary speed test may provide a deceptive representation of your internet's performance. While you subscribe to a designated speed from your ISP, that figure mostly serves as an indication of the greatest attainable speed at any moment. The real connection speed fluctuates throughout the day due to variables such as your ISP's routing and network congestion.
Speed test servers may encounter difficulties that distort your results, leading to a misleading perception of network sluggishness when it is functioning properly. Consequently, a single test will not provide a comprehensive understanding. Conduct repeated tests at various times throughout the day to obtain an accurate assessment of your internet speed.
The choice of instrument is significant; therefore, it is essential to do your tests utilizing several testing services. The optimal websites for assessing internet speeds are complimentary, therefore verifying results can aid in their validation.
4. Neglecting Server Location
When conducting a speed test, most tools automatically choose a test server, typically one that is geographically proximate to your location. Nevertheless, the chosen server may occasionally be situated at a considerable distance from your location, leading to reduced speeds.
The location of the server is significant as speed tests evaluate your connection to that particular server rather than the internet as a whole. The greater the distance to the server, the more network hops your data must traverse, resulting in increased latency and potential reductions in download or upload speeds.

To prevent this error, consistently verify the server utilized for the test. If the technology you utilize permits manual server selection, it is advantageous, since you can choose one that is geographically closer. Utilizing tools such as Ookla's Speedtest, one can manually select a server nearer to one's location for more reliable and accurate results.
Utilizing VPNs or Proxies During Evaluation
Conducting a speed test while utilizing a VPN or proxy can significantly distort your results. VPNs and proxies direct your traffic through an intermediary server, potentially situated in a different city or, more concerningly, a different nation. Consequently, they introduce latency to your connection through distance, encryption, or both, leading to significantly reduced speeds compared to your actual internet connection's potential.

Utilizing even the most rapid VPNs will prove ineffective. To obtain an accurate assessment of your network speeds, unplug your VPN or proxy server prior to testing. You can conduct a test both with and without the VPN to ascertain the extent of speed sacrificed for privacy.
Testing During Maximum Usage Periods
The timing of your speed test is also significant. Testing during high internet usage hours, such as evenings when the majority of individuals are engaged in streaming, gaming, or video conferencing, will yield deceptively low numbers. This may be due to network congestion experienced by your ISP.
Network congestion generally occurs between the late hours of 7 PM to 11 PM. During peak hours, ISPs may reduce internet speeds to alleviate network congestion. Testing solely during these hours may lead you to erroneously conclude that your connection is consistently subpar, while in fact, you receive adequate value at different times.
To obtain a more precise assessment of your actual internet speed, do tests at several times of the day, including off-peak periods.
Conducting Tests on Obsolete or Insufficiently Powered Devices
The hardware utilized for testing your internet speed significantly influences the results obtained. If you are utilizing an outdated computer, phone, or tablet, the hardware may serve as a bottleneck, resulting in performance outcomes that may not correctly represent the true speed.

Older devices possess significantly slower processors and obsolete network adapters that are incapable of properly utilizing high-speed connections. If your laptop is limited to Wi-Fi 4 (802.11n) or slower Ethernet connections with a maximum speed of 100Mbps, it restricts the maximum attainable speed irrespective of your internet package.
Despite purchasing gigabit speeds, your speed tests may not truly represent that due to hardware constraints. If you choose to use that outdated tablet for viewing content, make certain to transition to your newer and more proficient device for the examination.
Assessing your internet speeds is straightforward; however, achieving precise findings requires other considerations. Errors in measurement will prevent you from obtaining an accurate representation of your internet speeds. Prior to submitting a complaint to your Internet Service Provider, verify that you have accurately assessed your speeds.
