Test your internet speed in seconds. Free. No app needed.
WiFiSpeedTest.io measures your internet connection performance using multiple data points. The test downloads and uploads sample data to Cloudflare's global edge network, measuring throughput in real time. We calculate download speed, upload speed, latency (ping), and jitter to give you a comprehensive picture of your connection quality. All tests run entirely in your browser — no app installation required, and we never store your personal data.
Basic browsing and email: 1-5 Mbps is sufficient for web browsing, social media, and email. Most modern websites load quickly at these speeds.
HD video streaming: Netflix recommends 5 Mbps for HD quality and 25 Mbps for Ultra HD (4K). YouTube 4K requires about 20 Mbps. Multiple simultaneous streams multiply these requirements.
Online gaming: Most games need only 3-6 Mbps, but low latency (under 50ms ping) matters much more than raw speed. First-person shooters and competitive games benefit from ping under 20ms.
Video conferencing: Zoom, Teams, and Google Meet need 2-4 Mbps for HD video calls. Group calls with screen sharing may need 5-10 Mbps. Upload speed is especially important for video calls.
Working from home: A reliable 25-50 Mbps connection handles most remote work needs including video calls, cloud apps, VPN access, and large file uploads. Consider 100+ Mbps if multiple household members work or learn from home simultaneously.
Your speed test results can vary significantly depending on how you're connected. Ethernet (wired) connections deliver the most consistent speeds — often 95-100% of your plan speed. WiFi connections are affected by distance from your router, physical obstacles (walls, floors), interference from other devices, and the WiFi standard your router supports.
WiFi 6 (802.11ax) routers can deliver speeds up to 9.6 Gbps in theory, though real-world speeds are typically 300-1000 Mbps. WiFi 5 (802.11ac) maxes out around 100-400 Mbps in practice. If your speed test shows much lower speeds on WiFi than your plan allows, the bottleneck is likely your wireless connection, not your ISP.
Pro tip: For the most accurate speed test results, connect via ethernet cable and close other applications that use bandwidth. Test at different times of day — evening hours (7-11 PM) often show slower speeds due to neighborhood congestion on cable internet.
Latency (Ping) measures the round-trip time for a data packet to travel from your device to a server and back. It's measured in milliseconds (ms). Under 20ms is excellent for competitive gaming, 20-50ms is good for most uses, and over 100ms causes noticeable delays in real-time applications.
Jitter is the variation in ping times over multiple measurements. High jitter (over 15ms) causes choppy video calls, audio drops, and inconsistent gaming performance — even if your average ping is low. Consistent latency matters as much as low latency.
Packet Loss occurs when data packets fail to reach their destination. Even 1-2% packet loss can cause buffering, call drops, and gameplay issues. If you're experiencing packet loss, try restarting your router, checking cables, or contacting your ISP.

For most households, 100+ Mbps download is good. 25 Mbps is the minimum for HD streaming. 300+ Mbps is great for gaming and 4K video. Gigabit (1000 Mbps) is considered excellent.
Try: 1) Restart your router, 2) Use ethernet instead of WiFi, 3) Move closer to your router, 4) Close background apps using bandwidth, 5) Upgrade your internet plan, 6) Check for interference from other devices.
Ping measures the round-trip time for data to travel to a server and back, in milliseconds. Lower is better — under 20ms is excellent for gaming, under 50ms is good for most uses, and over 100ms may cause noticeable lag.
Download speed determines how fast you receive data (streaming, browsing, downloading files). Upload speed is how fast you send data (video calls, uploading to cloud, live streaming). Most home connections have faster download than upload.
Several factors can reduce speeds: WiFi signal degradation, network congestion during peak hours, router limitations, old ethernet cables (Cat 5 vs Cat 6), background downloads, VPN overhead, and distance from your ISP's equipment. Run a wired speed test first to rule out WiFi issues.
Test weekly for general monitoring. Test more frequently if you notice streaming buffering, gaming lag, or slow downloads. Running tests at different times helps identify if your ISP throttles during peak hours. Keep a log to track trends over time.
WiFiSpeedTest.io uses Cloudflare's global edge network for testing, providing accurate results from servers near your location. For best accuracy: use a wired connection, close other apps, and run the test multiple times. Results may vary based on your device, browser, and current network conditions.
