39 TROUBLESHOOTING TIPS
If you encounter problems running SmartSDR for Windows, please use the following troubleshooting
tips. If these tips do not solve the problem, please submit a HelpDesk support ticket for assistance
from FlexRadio Systems.
39.1 FLEX-6000 DOES NOT SHOW UP IN THE RADIO CHOOSER
If the FLEX-6000 does not show up in the Radio Chooser, the most probable fault is network related.
There are several network components that can be at fault.
39.1.1 Physical Layer Issues
After connecting your FLEX-6000 to a network router, an Ethernet switch or directly to your PC, check
to make sure the FLEX-6000 is properly connected at the network physical layer.
Looking at the back of the FLEX-6000 at the Ethernet connection, below the connector on the left is
the link state LED. It should be illuminated Yellow when the radio is powered on. If not, you do not
have a physical layer connection and you should check or try the following:
• Make sure the Ethernet cable is plugged all the way in on both ends. A click should be heard
when it is seated completely.
• Make sure the network router, PC or Ethernet switch is powered on before powering up the
FLEX-6000.
• Most network routers and Ethernet switches will have their own link state LEDs associated
with the port the FLEX-6000 is connected. Check to make sure the link state LED for the port
connected to the FLEX-6000 is illuminated. Please refer to your network hardware manual
for additional information
• Power cycle the FLEX-6000 to re-initialize the Ethernet port.
39.1.2 Firewalls Preventing Network Access from the FLEX-6000
The FLEX-6000 broadcasts a network discovery packet (message) that is received by SmartSDR for
Windows. SmartSDR for Windows uses this information to populate the Radio Chooser. Therefore,
if the FLEX-6000 is not displayed in the Radio Chooser or after connecting to a FLEX-6000 there is no
spectrum displayed, one reason may be that a software firewall on your PC is preventing access. The
SmartSDR for Windows Installer automatically modifies the Windows firewall to allow the FLEX-6000
discovery packet and other network traffic to pass properly but does not modify third-party firewalls.
A third-party firewall will most likely block access to the FLEX-6000. You may not be aware that
secondary PC level firewalls are installed on your PC, so if you experience connectivity problems, this
is the first thing to check.
Additionally, you may have a firewall running on a network router, which is referred to as a
“hardware” firewall. It too can be improperly configured and may prevent network access between
the FLEX-6000 and SmartSDR for Windows.
In these cases, the action to resolve this condition is to modify the third-party firewall software to
allow access from any host on your local network to SmartSDR for Windows by allowing all TCP and
UDP port access to SmartSDR for Windows.
