Flex 6300 has been running great, was operating this afternoon, clicked some control on screen, don't recall what, and received a Connection Lost window with message The connection to the radio was lost. Please reconnect. I am now unable to get beyond this problem. I clicked ok and the Radio Setup screen reports the Flex-6300 In Use (126.96.36.199) and has a yellow Update. The cycle repeats as follows: shut down 6300 by holding in the power button until the power stops. The Radio Setup screen Radios goes blank and the yellow Update continues. Reboot the 6300, after green light goes steady the Radios shows the Flex-6300 available. Click on Available, yellow Update becomes green Connect. Click on Connect, Smart SDR reports client connected at 188.8.131.52 but no live activity displayed, just controls on the right, and the TNF CWX on the bottom. The mouse is live, I can click on CWX and get the screen. After about 5 seconds the Connection Lost screen displays and the entire cycle is repeated. I have rebooted the computer numerous times and tried a different Ethernet cable.
