Internet Speed Test – Check Ping, Download & Upload Speed

Measure WiFi and mobile broadband ping, jitter, download and upload speed through a nearby server.

Before you start

What this internet speed test measures

This free online internet speed test measures WiFi and broadband performance from your browser, including ping latency, download speed and upload speed in megabits per second.

Use it to verify whether your connection matches your plan, compare WiFi with Ethernet, or document results before contacting your ISP. After a slow result, continue with the network diagnostics suite for DNS lookup, ping tests and port checks.

Close heavy downloads, pause VPN software when appropriate and run the test several times at different hours for a fair comparison.

Check if you get the speed you pay for

  1. Run the test on Ethernet first, then repeat on WiFi.
  2. Compare the result with the speed stated in your broadband plan.
  3. Review upload speed separately for video calls and cloud backup.
  4. If wired results stay low, use the bandwidth calculator to estimate expected usage.

WiFi feels slow in some rooms

  1. Run the test near the router and again in the weak area.
  2. Close background downloads, updates and streaming apps.
  3. Check latency and jitter — they matter for calls and gaming.
  4. Improve coverage with the router setup guides.

A website or app feels slow

  1. Measure your own connection speed first.
  2. If your speed looks healthy, run a website audit on the target URL.
  3. For naming issues, use DNS lookup.
  4. For routing problems, try traceroute on the hostname.

Understand your internet speed test results

Start the Zerolink internet speed test to measure ping, download speed and upload speed. Latency shows response time in milliseconds, while download and upload speeds show data transfer in megabits per second.

For a useful comparison, pause large downloads, disconnect VPN software when appropriate and repeat the test over WiFi and Ethernet at different times instead of judging the connection from one measurement.

Why Test Your Internet Speed?
Diagnose
Know if your ISP, WiFi, router, or device is the issue.
Verify
Compare actual vs advertised speed. Document for ISP disputes.
Optimize
Find WiFi dead zones. Position router or upgrade equipment.
How Activities Affect Speed
Streaming: Required speed varies with resolution, codec and simultaneous viewers.
Video calls: Upload stability and latency matter as much as headline download speed.
Gaming: Consistent low latency usually matters more than maximum throughput.
Remote work: Allow capacity for calls, cloud sync and every active device.
What Affects Speed Test Results?
Network congestion: Shared networks can slow down when more users are active.
WiFi conditions: Distance, walls, interference and device capability affect wireless performance.
WiFi vs Ethernet: A wired comparison helps reveal whether the wireless link is the bottleneck.
Background Activity: Downloads, updates, cloud sync reduce test speed. Close other apps first.
VPN connection: Encryption and a distant VPN endpoint can affect throughput and latency.

Who this speed test is for

Run this as a wifi speed test when rooms feel slower than the plan, or after a new fibre activation. It also works as an independent check if you are comparing Airtel, Jio or BSNL performance — it measures your live path, not a branded ISP widget.

Households and offices on Zerolink broadband in Gharaunda, Panipat and Karnal can run the same WiFi speed test on wireless and Ethernet, then open the local broadband page if results stay below the subscribed plan after a reboot.

Close bandwidth-heavy apps, press Start Speed Test and keep the tab open while latency, download and upload are measured. Repeat the test under similar conditions to compare results.

The speed you need depends on video quality, the number of simultaneous users and the applications in use. Compare your result with the current requirements published by each service and with the speed included in your internet plan.

Slow speed may be caused by WiFi distance from the router, network congestion, background transfers, a VPN, provider conditions or device limitations. Restart the router, pause transfers and compare WiFi with Ethernet before contacting the provider.

Latency is the measured response time to the selected endpoint in milliseconds. Lower and more consistent latency generally makes calls, games and interactive applications feel more responsive.

The tool transfers test data through M-Lab NDT7 when available and an alternate measurement endpoint when necessary. Results are a snapshot of current conditions, so close bandwidth-heavy applications and repeat the test at different times for a more useful comparison.

More advanced questions

Broadband is the connection supplied by your Internet Service Provider. WiFi is the wireless link between your device and router, so distance, walls, interference and device capability can make a WiFi result lower than a wired Ethernet result.

Internet speed varies because of network congestion, WiFi conditions, background activity, server routing and device performance. Test at different times under comparable conditions to understand the pattern.

Streaming requirements vary by provider, resolution, codec and the number of simultaneous streams. Check the current recommendation from the streaming provider and allow additional capacity for other active devices.

Upload performance affects video calls, file transfers, cloud backup and content publishing. The capacity you need depends on application requirements and how many devices upload at the same time.

Greater distance, walls and radio interference can weaken WiFi and reduce measured speed. Compare a test near the router with a wired Ethernet test to identify whether the wireless link is limiting performance.

Yes. On WiFi it measures the connected broadband service; on cellular data it measures the current mobile connection. Mobile results vary with signal strength, location, radio conditions and network congestion.

Restart the router, pause background transfers, test closer to the access point and compare with Ethernet. If repeated wired tests remain below the conditions stated in your plan, ask the provider to check the connection.

Using this speed test with Zerolink broadband in Haryana

Run a wifi speed test after installation or when streaming feels slow. Homes and offices on Zerolink fibre in Gharaunda, Panipat and Karnal can compare WiFi versus Ethernet results, then open the local broadband page if the plan speed needs a follow-up.
