+# Check Network Quality Stats From The Command Line
+
+MacOS comes with a little known CLI utility for checking your current network
+quality statistics. It is aptly named `networkQuality`.
+
+Here is what a basic run of the tool might output:
+
+```bash
+$ networkQuality
+
+...
+Downlink: capacity 281.430 Mbps, responsiveness 101 RPM - Uplink: capacity 16.629 Mbps, responsiveness 101 R
+Downlink: capacity 285.534 Mbps, responsiveness 101 RPM - Uplink: capacity 16.028 Mbps, responsiveness 101 R
+==== SUMMARY ====
+Uplink capacity: 22.982 Mbps
+Downlink capacity: 288.152 Mbps
+Responsiveness: Low (93 RPM)
+Idle Latency: 26.375 milliseconds
+```
+
+You can get an even more detailed summary with the `-v` option:
+
+```bash
+$ networkQuality -v
+
+...
+==== SUMMARY ====
+Uplink capacity: 18.257 Mbps (Accuracy: High)
+Downlink capacity: 469.355 Mbps (Accuracy: High)
+Responsiveness: Medium (252 RPM) (Accuracy: High)
+Idle Latency: 25.583 milliseconds (Accuracy: High)
+Interface: en0
