Troubleshooting
If you are having difficulties connecting to the device on Linux, quickly verify proper setup with the
following steps.
- Verify the device is connected to the correct network interface, the device power cable is
plugged in and the LED on the device is solid green. The LED should be solid green ~12
seconds after power is applied if a valid network connection is detected.
- Verify the correct profile is selected in the Network Settings for the given network interface.
- Use the commands in the Network Configuration commands section to view and verify all
network parameters have been properly set.
- Use the following commands to determine if any network errors or overruns have
occurred.
$ netstat -su
$ netstat -i
$ ip -s link
- Disable hyperthreading. If you find that during operation (such as I/Q streaming) one of
the CPU cores is at or near 100%, this could be the source of data loss. Network traffic is
handled on a single thread in the kernel. If that thead is saturated, and unable to handle
the transfer rates of the device, data loss can occur leading to device disconnection
events. Disabling hyper threading could increase the single threaded performance of the
PC alleviating this issue. You can disable hyperthreading in the BIOS of some PCs. If this
has no effect, Signal Hound recommends re-enabling hyperthreading as it can impact the
performance other other heavily threaded applications.
