The Graphs page shows every metric as a time-series chart — signal strength, latency, speed and more, plotted over time so you can see exactly when things change. This is where you go to answer questions like:
- "Is my WiFi slower in the evenings?"
- "When did that dropout happen?"
- "Is 5 GHz consistently faster than 2.4 GHz?"
- "Has my connection been getting worse over the past week?"
Available graphs
Filters and controls
Time window
The Window dropdown controls how far back the graphs show data. Options are 1h, 6h, 12h, 24h, 48h, and 7 days. Zoom into a specific incident with 1h or 6h; zoom out to see weekly patterns with 7 days.
Band filter
The Band dropdown lets you show both bands together, or isolate a single band. Showing both is useful for comparison — if 5 GHz degrades while 2.4 GHz stays stable, the issue is band-specific rather than a general internet problem.
Refresh
Click the Refresh button to reload data without reloading the whole page. Graphs don't auto-update — use this after a manual test run or to check for new data.
Reading the graphs
Each graph plots time on the X axis and the metric value on the Y axis. Both bands are overlaid on the same chart — blue for 2.4 GHz and green for 5 GHz.
Gaps in a line indicate that the test returned no result for that cycle — either the connection was down, the Pi couldn't associate to that band, or the test timed out. A gap is more informative than a zero value, as it tells you something actually failed rather than measured at zero.
Common patterns to look for
Evening slowdowns
Download speed drops consistently between 6–10 pm. Classic network congestion — your ISP's infrastructure is overloaded during peak hours.
Latency spikes
Gateway ping spikes to hundreds of ms but external ping is fine. Usually indicates WiFi interference or a device causing local network congestion.
Gradual degradation
Speeds slowly decline over days or weeks. Could indicate a failing router, interference from new neighbouring networks, or ISP issues.
Band discrepancy
5 GHz ping is consistently much lower than 2.4 GHz. Normal — 5 GHz has lower latency when close to the router. Large differences when far away suggest range issues.
Packet loss bursts
Packet loss graph shows periodic bursts rather than continuous loss. Common with microwave ovens, baby monitors, and other 2.4 GHz interference sources.
Overnight issues
Problems only appear between midnight and 6 am. Could be scheduled router maintenance, ISP network work, or automatic firmware updates on your devices.
