Test your WiFi speed with our free wireless internet test. Check your wireless connection from any device — no software, results in under 30 seconds.
A wireless internet test measures your internet speed while connected over WiFi. Most people test their internet wirelessly because that's how they use it. SpeedCheckTest lets you run a wireless internet test from any device in seconds.
Running a wireless internet test takes under 30 seconds:
Note: Your WiFi speed will typically be 20–50% lower than your plan's maximum due to wireless overhead. To find your true connection speed, test over Ethernet. Your WiFi result tells you what your actual wireless performance is.
Your internet plan speed (e.g., 200 Mbps) is the maximum wireline capacity your ISP delivers to your home. When you connect over WiFi, the wireless connection adds overhead that reduces your actual throughput:
Your WiFi speed depends heavily on which WiFi standard your router and device support:
| WiFi standard | Max speed | Typical real-world | Best for |
|---|---|---|---|
| WiFi 4 (802.11n) | 600 Mbps | 50–200 Mbps | Older devices, basic use |
| WiFi 5 (802.11ac) | 6.9 Gbps | 200–500 Mbps | Most modern devices |
| WiFi 6 (802.11ax) | 9.6 Gbps | 400–1,200 Mbps | Modern devices, dense networks |
| WiFi 6E / 7 | 46 Gbps | Up to 2,000 Mbps | Latest devices, fiber plans |
If your wireless internet test shows lower speeds than expected, try these fixes:

What should your WiFi speed test show? Here are real-world benchmarks:
| Scenario | Good WiFi speed |
|---|---|
| Close to router, WiFi 6, 5 GHz | 300–800 Mbps |
| Same room, WiFi 5, 5 GHz | 100–300 Mbps |
| Different room, through 1 wall | 50–150 Mbps |
| Far from router, 2.4 GHz | 20–80 Mbps |
| Multiple walls, many devices | 10–50 Mbps |
If you're getting 50 Mbps or less close to your router, your router is likely the bottleneck. If your plan is 100+ Mbps and you're getting 10–20 Mbps far from the router, distance and interference are the cause.
WiFi and Ethernet both connect you to the internet, but they differ significantly:
| Factor | WiFi | Ethernet |
|---|---|---|
| Speed | 20–500 Mbps (real-world) | Near 100% of plan speed |
| Latency | 1–5 ms added | Minimal added latency |
| Reliability | Varies with interference | Stable, consistent |
| Convenience | Wireless, any room | Requires cable runs |
| Best for | Phones, tablets, casual use | Gaming, work, streaming |
Your WiFi speed is typically lower than your actual internet connection speed due to wireless overhead. To know your true internet speed, test over Ethernet. Your WiFi result reflects real-world performance for the way you actually use the internet.
Different devices have different WiFi chips. A phone with WiFi 6 gets faster speeds than a laptop with WiFi 5. A modern laptop close to the router will show higher speeds than an older phone further away.
Yes. The 2.4 GHz band has longer range but lower maximum speeds (up to 600 Mbps theoretical). The 5 GHz band offers higher speeds (up to 9.6 Gbps with WiFi 6) but shorter range. Use 5 GHz for speed, 2.4 GHz for coverage.
For basic WiFi use: 25–50 Mbps is enough for web browsing and email. For streaming HD video: 50–100 Mbps. For 4K streaming on multiple devices: 200–500 Mbps. For a household with heavy use: 300–1,000 Mbps.
Yes, especially on the 2.4 GHz band. In dense neighborhoods, many WiFi networks overlapping on the same channels causes congestion. Switching to 5 GHz or 6 GHz (WiFi 6E) avoids this interference.
A wireless internet test measures your WiFi speed, which is typically 20–50% lower than your plan's maximum due to wireless overhead. Run the test close to your router for a baseline, then at your normal usage location. If speeds are too low, try moving closer, switching to 5 GHz, reducing interference, or upgrading your router. For the true speed of your connection, test over Ethernet.
