Network Diagnostics

The Network Diagnostics dialog provides a live view of the network link to the radio. It features a multi-pane layout with a navigation tree on the left and a content area on the right. Pages include an overview dashboard, detailed metrics, per-stream performance graphs, an application log viewer, and a TCI clients page.

Opening Network Diagnostics

1. Go to Settings > Network....
2. The Network Diagnostics dialog opens.

Navigation

The left pane contains a tree navigation widget that lists all available diagnostic pages. Click any page name to display its content in the right pane.

A search field at the top of the navigation tree lets you filter the list by typing part of a page name.

Pages

The dialog contains the following pages, selectable from the navigation tree:

• Overview – Shows four health cards (Status, Latency, Packet Loss, Audio Buffer) and four time-series charts (Latency and Jitter, Recent Packet Loss, Total Stream Rates, Audio Buffer).
• Connection Details – A scrollable grid with labeled values for Network Status, Incoming Stream Rates, Packet Loss, Audio Playback, and the Adaptive Frame-Rate Throttle subsection. Includes a Read-Only Clipboard Copy action to copy the whole diagnostic summary. Renamed from "Details" in the v26.8.4 tree-navigation rework.
• Latency – Full-width time-series chart of RTT, arrival gap, and jitter in ms.
• Rates – Full-width log-scale time-series chart of per-stream incoming bitrates (RX total, Audio, FFT, Waterfall, Meters, DAX) in kbps.
• Packet Loss – Full-width time-series chart of packet loss percentage per stream category.
• Audio – Full-width time-series chart of playback buffer fill (ms) and underruns per second. Includes per-stream RX audio diagnostics showing feed rate, deficit, late packets, packet class code, and stream health for each active audio stream.
• Logs – Live tail of the AetherSDR log file, filtered by category checkboxes. Syntax-highlighted by log level and category name. The timeframe selector is hidden while this page is active.
• TCI Clients – Lists connected TCI clients with a live traffic monitor (Pause/Save log/Clear), answer-command suppression controls, and per-client details. New in v26.8.4. Build-gated by HAVE_TCI / TCI support. The timeframe selector is hidden on this page.

Timeframe selector

A dropdown at the top-right corner of the content area selects how far back the time-series charts display history. The following options are available:

• 1 minute
• 5 minutes (default)
• 15 minutes
• 1 hour
• 1 day
• 1 week

The timeframe selector is hidden when the Logs or TCI Clients page is active.

Pause log scrolling to inspect an older entry

The Logs page tails the AetherSDR log file in real time. This section explains how to pause that automatic scrolling so you can read an older entry without it jumping away, and how to resume live tailing when you are done.

Steps

1. Open Network Diagnostics via Settings > Network....
2. Click Logs in the navigation tree.
3. To pause scrolling, do either of the following:
4. Scroll up in the log viewer. The viewer automatically switches to Paused.
5. Click the toggle button, which reads Live, to switch it to Paused.
6. Read the entry you need. The display stays fixed while the button shows Paused.
7. When you are ready to return to the live tail, click the toggle button, which now reads Paused, to switch it back to Live. The viewer immediately jumps to the newest output and resumes auto-scrolling.

Logs page controls

Control	Default	Behavior
Live / Paused (toggle button)	Live	When set to Live, the viewer auto-scrolls to the newest log output. When set to Paused, scrolling stops and the display holds its current position. Scrolling up in the viewer automatically switches the button to Paused. Clicking the button while it reads Paused resumes auto-scrolling and jumps to the tail.
Filter Categories (checkboxes)	–	Per-category checkboxes filter the log view. Includes a "General" (default) category plus all registered LogManager categories.
Select All (push button)	–	Shows all log categories in the viewer.
Deselect All (push button)	–	Hides all log categories from the viewer.

Tips

• Scrolling up is the fastest way to pause — you do not need to reach for the toggle button first.
• The log view is syntax-highlighted by log level and category name, which makes it easier to spot the entry you are looking for.
• Category filter checkboxes and the Select All and Deselect All buttons remain active while paused, so you can narrow the visible entries without resuming live scrolling.

Indicators

The dialog displays the following indicators:

Indicator	Meaning
Status	Overall link quality, color-coded green → red. States: Excellent, Very Good, Good, Fair, Poor
Target Radio IP	IP of connected radio, or "Not connected"
Selected Source	Local NIC/bind path used for the connection
Local TCP	Local TCP endpoint
Local UDP	Local UDP endpoint
First UDP Packet	Whether the first UDP packet has been received since connect (Yes/No)
Latency (RTT)	Current round-trip time. Displays "not measured on this link" when the transport has no round trip to time.
Max Latency (RTT)	Highest RTT seen since connect. Displays "not measured on this link" when the transport has no round trip to time.
Audio / FFT / Waterfall / Meters / DAX rates	Per-category ingress rate in kbps. Displays "n/a" when the transport does not provide per-stream category statistics.
Total RX / Total TX	Aggregate bytes per second in each direction
Audio / FFT / Waterfall / Meters / DAX drops	Per-category dropped-packet counts and percentage. Displays "n/a" when the transport does not provide per-stream category statistics.
RX Buffer Now / Peak	Current and peak audio buffer fill in bytes and ms
Underruns (total / last sec)	Audio underrun counters
Audio Arrival Gap / Max Arrival Gap	Inter-packet arrival timing. Displays "not measured on this link" before the first delivery-timing window closes.
Network Jitter	Smoothed jitter estimate of audio stream in ms. Displays "not measured on this link" before the first delivery-timing window closes.
Adaptive Frame-Rate Throttle	Current State, Pending Lift, and Sessions This Run values. Reduces panadapter frame rates when latency or loss is detected. Hidden until throttle data is available.
Log path label	Full path of the log file being tailed
