WiFi Speed Test.

Connect to your WiFi, pause other heavy network activity, and select GO. Keep the tab open while the test measures download, upload, HTTP latency, and jitter. Repeat in different rooms to compare your connection.

It depends on what you do and how many devices share the connection. This site uses 5 Mbps as an indicative HD streaming threshold and 25 Mbps for 4K. Calls and gaming also depend on stable upload and response time. These are guides, not service guarantees.

Distance, walls, interference, busy devices, your broadband plan, congestion, and the route to the test server can all reduce the result. Compare a test close to the router with an Ethernet test before drawing conclusions.

Download measures data arriving at your device; upload measures data leaving it. Streaming mostly downloads. Video calls, sharing photos, and cloud backups also rely on upload capacity.

Our latency figure is the average round-trip duration of small HTTP requests. Jitter is the average absolute difference between successive round trips. This is application latency, not a precise ICMP ping or a direct measure of radio interference.

Move the router into an open, central position. Test nearer to it, pause competing transfers, compare frequency bands if available, and try Ethernet. Repeat at different times and compare against your plan before contacting your provider.

Yes. No account or payment is required. The test transfers real data and may use up to the configured data budget shown in settings, so normal mobile or metered connection charges can still apply.

Yes, in modern browsers with streaming Fetch support. Tests reflect whichever network your phone uses at the time. Background throttling, battery saving, VPNs, and changing networks can affect results.
