Measure browser-to-edge performance and display browser-reported estimates. Radio signal and channel data remain unavailable.
This page measures HTTP download throughput and round-trip time between your browser and this site's Cloudflare edge. When the browser exposes the Network Information API, it also shows that API's rounded bandwidth and RTT estimates. The API has limited browser availability and does not expose WiFi radio strength, channel use, or nearby networks.
Use your operating system, router interface, or a trusted native analyzer to inspect radio strength in dBm, channel occupancy, and neighboring access points. This page does not infer those values from speed.
Band performance depends on the access point, client, walls, distance, and local spectrum use. Microsoft's current Teams network guidance notes that 2.4 GHz can be affected by other consumer devices and that 5 GHz is better suited to real-time media but needs denser access-point coverage. Compare bands in the same location instead of assuming one will win. Source: Microsoft Teams network guidance.
Record radio details with your operating system or router, establish a repeated baseline, change one location or setting, and repeat. Follow the access-point vendor's placement, channel, band, and firmware guidance for the exact model. The browser result alone does not justify a hardware purchase.
It measures browser-to-edge throughput and RTT. Supporting browsers may expose rounded Network Information API estimates. It cannot measure WiFi radio strength, channels, or nearby networks.
Use your operating system, router interface, or a native analyzer that can read dBm and channel information. Browsers do not expose those radio measurements.
A browser measurement can be affected by the device, browser, other traffic, WiFi conditions, the access network, and the route to the test edge. Compare repeated runs and an Ethernet run before assigning a cause.
Use the streaming provider's current requirement. For example, Netflix lists 3 Mbps for 720p HD, 5 Mbps for 1080p, and 15 Mbps for 4K per stream. Source: Netflix Help Center.
Use the same device and location, record several baseline runs and router/OS radio data, change one variable, and repeat. Follow the hardware vendor's model-specific guidance.
