What Smart Diagnostics Does

Most people know their internet "feels slow" but can't pinpoint why. Smart Diagnostics runs a battery of network checks in sequence and translates the raw data into clear, actionable results. Instead of staring at a gateway-latency number, you get a recommendation like "Your latency to the gateway is high -- try restarting your router or moving closer."

One-Tap Analysis

No configuration needed. Tap once and PingKit checks your network interface, gateway, DNS servers, internet reachability, HTTPS connectivity, and download speed automatically.

Six-Step Sequence

Checks your network interface, gateway ping, internet reachability, DNS resolution, HTTPS connectivity, and download speed in sequence. Covers every layer of your connection in seconds.

Actionable Results

Each finding comes with a specific recommendation. Not just "high latency detected" but "latency is 180ms to your gateway -- this suggests Wi-Fi congestion, try switching to 5GHz."

Plain English

Results are written for humans, not network engineers. Color-coded health indicators and clear explanations make it easy to understand what's wrong and what to do.

When to Run Smart Diagnostics

Quick Network Health Check

Wonder if your connection is actually fine or just barely working? Smart Diagnostics gives you a definitive answer in under 30 seconds. It checks every layer from your Wi-Fi link to the public internet and grades each one. Use it as a daily spot check or whenever something feels off.

Before Calling ISP Support

ISP support calls are painful. They'll ask you to restart your router, check your cables, and run their own speed test -- all of which takes 45 minutes. Run Smart Diagnostics first and you'll have concrete evidence: "My gateway latency is 4ms but external latency is 340ms, so the problem is upstream of my router." That skips straight past the script.

After Changing Router Settings

Changed your DNS server? Switched Wi-Fi channels? Enabled QoS? Run Smart Diagnostics before and after to see if your changes actually improved anything. The multi-test approach catches regressions that a simple speed test would miss -- like faster downloads but worse DNS resolution.

Regular Maintenance

Networks degrade gradually. A weekly diagnostic catches slowly rising latency, a gateway that's gone flaky, or DNS servers that have become unreliable. By the time you notice slow video calls, the problem has usually been building for days. Regular testing catches it early.

Diagnostics That Actually Help

The problem with most network diagnostic tools is that they dump raw numbers on you and expect you to interpret them. PingKit's Smart Diagnostics is built differently -- it understands what those numbers mean in context. A 50ms ping is great for browsing but concerning if it's to your own router. 340ms to reach the public internet while your gateway responds in 4ms points squarely at your ISP, not your Wi-Fi. Smart Diagnostics applies this context automatically and tells you what matters for your specific situation.
