How this test works
We send a series of small requests to measure latency and jitter, then run a brief download sample to estimate throughput. All measurements happen in your browser.
- • Latency comes from round-trip times to our test endpoint.
- • Jitter reflects the variation between those round trips.
- • Throughput is a short burst, not a prolonged bandwidth test.
Troubleshooting
- • Move closer to the router or switch to 5 GHz to reduce interference.
- • Plug in with Ethernet for the most consistent results.
- • Pause downloads, backups, or streams while testing.
- • Restart the router or modem if latency stays high across multiple runs.
- • Turn off VPNs or corporate proxies to compare direct results.
Quick steps
- • Run the test and note latency, jitter, and download estimates.
- • Rerun once or twice to spot consistent values versus one-off spikes.
- • If on Wi-Fi, face the router and keep line of sight for the test run.
- • Close other tabs that stream video or cloud sync heavy files.
Interpret the numbers
- • Latency: under 100 ms is fine for video calls; under 50 ms feels snappy.
- • Jitter: under 30 ms avoids choppy audio; lower is better.
- • Download: 5-10 Mbps per HD stream is usually enough for most meeting apps.
- • Packet loss: any visible loss can cause glitches; retest after fixing Wi-Fi or cables.
If results swing a lot
- • Test on Ethernet to rule out Wi-Fi noise.
- • Change Wi-Fi channel or move away from microwave or cordless phone interference.
- • Check for VPN overhead; disable it temporarily if possible while testing.
- • Reboot the router to clear buffers if it has been running for weeks.
Improve Wi-Fi stability
- • Place the router higher and in the open; avoid closets and metal shelves.
- • Use 5 GHz for short range and less congestion; use 2.4 GHz only for distance.
- • Reduce smart-home chatter by splitting IoT devices to a guest network if available.
- • Update router firmware to the latest version.
Reduce bufferbloat
- • Enable Smart Queue Management or QoS on your router to keep latency stable during uploads.
- • Avoid large uploads or cloud backups during calls; schedule them for later.
- • Cap bandwidth on secondary devices if they saturate the link.
Ethernet checklist
- • Use a known-good cable rated for the speed you expect (Cat5e or better for gigabit).
- • Bypass powerline adapters to see if they add latency or jitter.
- • Connect directly to the modem to rule out router issues, then put the router back.
Work or school networks
- • Firewalls or proxies can shape traffic and add delay.
- • If numbers are high only on the corporate VPN, ask IT about split tunneling for calls.
- • Schedule calls outside peak hours if bandwidth is shared heavily.
Plan for peak times
- • Run the test morning, midday, and evening to learn how your connection changes.
- • If evenings are congested, join calls with video off or on a lower resolution.
- • Consider upgrading plan speed or using wired connections during busy hours.
Mobile hotspots
- • Place the phone near a window for better signal.
- • Disable downloads and cloud backups on the phone while tethered.
- • Expect higher jitter during cell handoffs; rerun the test if you move.
When to use this test
- • Right before a call when you suspect lag or audio glitches.
- • After switching ISPs or routers to validate performance.
- • When diagnosing video call dropouts alongside device tests.
- • Before traveling, to compare hotel or hotspot quality quickly.
Safety and privacy
- • Only small requests are sent; no personal content is uploaded.
- • Results stay in your browser and disappear when you close the tab.
- • You can rerun as often as you like without heavy data use.

FAQ
What latency is good for calls?
Aim for latency under 100 ms and jitter under 30 ms for stable HD calls.
Is this a full speed test?
No. We run light throughput samples to gauge readiness without consuming large data.
Will this use much data?
No. The checks use small pings and brief downloads so you can rerun them safely.
Does a VPN change results?
Yes. VPNs add latency. If numbers look high, retest with the VPN off or on split tunneling.
Is upload tested?
We focus on latency, jitter, and a brief download. For streaming, run a dedicated upload test after this quick check.
Why do results spike at the start?
Wi-Fi and VPN links often ramp up. Run two or three passes and focus on the stable values rather than the first spike.
