How we measure: a real-world test to a neutral point on the open internet, not a server inside your provider network, so it reflects everyday speed and can read slightly below best-case on-network tests.

We record anonymized results (speed, latency, your provider and coarse location) to publish honest, real-world speed data by provider. No personal information is stored.

Neptuno Networks Speed Test FAQ

Why is my Neptuno Networks speed lower than advertised?

Advertised speeds are “up to” peaks measured on an ideal connection. Real-world speed to a neutral point on the open internet runs a few percent lower, and Wi-Fi, older equipment, or peak-hour congestion lower it further. For the truest read of your Neptuno Networks line, test over a wired connection.

How does ISPReports measure Neptuno Networks speeds?

Tests run against the nearest of Cloudflare’s edge locations, so the result reflects your access network rather than a server inside Neptuno Networks’s own network. We verify each result by network operator, aggregate it as a median (not an average, which a few fast tests would skew), and only publish a provider’s measured speeds once enough independent tests exist. We do not accept provider-submitted numbers.

Is Neptuno Networks good for gaming and video calls?

Run the test above. The connection-quality grade reads latency under load and packet loss, which determine whether calls and games stay smooth, beyond the raw download number.
