crashes with 4.1.5

ka1jy · December 30

I seem to be getting more than a few crashes showing dot net exceptions with this version. Just sitting there monitoring digital stuff with wsjt and jtalert running. It might run for 6 hours and then suddenly dump. Anyone else seeing stuff like this? I wasn't having any issues with 3.10 or whatever I had before 4.x

None here . . . Mine will run for days with no crashes. Turned the radio off twice in the last month of ownership

No problem with my 6400 or 8600 both running 4.1.5. You might want to try a factory reset if you haven't already. Be sure to export your profiles first.

I have done the factory reset. This radio crashes 3 times a week. This morning it dropped off the network. Didn't even answer pings. I used a fixed IP address so it was off. No problem with the cables, unmanaged ethernet switch or anything else on the network. I think I got stuck with a used lemon.

Hi

Let's do some testing just to be sure it isn't the switch. Gigabit switches seem to be problematic, especially the lower quality versions. You may also want to try using just a 100mb switch and see if the problem goes away. Sadly, not all switches are equal. Some are just .. junk to be honest.

We want to do this before sending something in for repair as this is the test they run when diagnosing a communications layer issue. It creates a very simple network.

Diagnosing Network Issues with a Link-Local Test

A Step-by-Step Guide for FlexRadio Users

Introduction

FlexRadio transceivers rely on stable network connections for optimal performance. If you’re experiencing disconnects, audio dropouts, or other network-related issues, performing a Link-Local Test helps determine whether the problem lies with your radio or your network.

This test directly connects your PC to the radio, bypassing any external network components.

This document outlines how to conduct the test and interpret the results.

Why Perform a Link-Local Test?

Isolates the Problem – Helps determine if the issue is related to your network or the radio itself.
Eliminates Variables – By removing routers, switches, and other network devices, we can focus on potential hardware or software issues.
Simplifies Troubleshooting – If the radio works properly in this test, then the issue is within your network setup.

Step-by-Step Instructions

1. Gather Required Equipment

Your FlexRadio transceiver
A PC or laptop running the latest version of SmartSDR
A single NEW LAN (Ethernet) cable

2. Power Down Your Equipment

Turn off both your PC and your FlexRadio completely.
Unplug any existing network connections to ensure no external devices are affecting the test.

3. Directly Connect the Radio to the PC

Use an Ethernet cable to connect your PC directly to the LAN port on the FlexRadio.
Do not connect the radio or PC to any router, switch, or other network devices.

4. Power Everything Back On

First, turn on your radio and allow it to fully boot.
Then, turn on your PC and let the operating system load completely.

5. Launch SmartSDR

Open SmartSDR on your PC.
In the radio chooser window, check if your radio appears as an available device.

Interpreting the Results

✅ If the radio appears and works correctly:

Try to recreate the same problem. If you are not able to, then this means your radio is functioning properly, and the issue likely stems from your network setup.

The next steps are:

Check for faulty Ethernet cables, switches, or routers.
Ensure your network is properly configured for SmartSDR.
Look for any network congestion or interference.

❌ If the radio does NOT appear or crashes:

This could indicate a hardware or software issue with the radio or PC. In this case:

Restart the test to confirm consistent failure.
If the issue persists, contact FlexRadio Support and report your findings.

Conclusion

The Link-Local Test is a crucial step in troubleshooting network-related issues with your FlexRadio system. By eliminating network components, you can quickly determine whether the problem is internal to your radio or caused by your home network.

If you require further assistance, please reach out to FlexRadio Support with your test results.
