Flex6400 with direct internet connection looses after several hours connection.

Hi all,

Have a FLEX6400 (4.1.5.39794) which is wired directly to a 1GB switch with the PC and then off to the router.

The issue is the radio internet status goes to NONE after X hours of use/none use.

My setup is using either DHCP or manually assigned IP address.
SmartSDR and all the other programs connect perfectly.
Network switch is unmanaged with no smart features/firewalls etc.

From the router you can ping the FLEX:
Reply from 192.168.0.40: bytes=64 ttl=64 seq=4 time=0.678 ms

UPnP shows:

FlexRadio SmartLink TLS Port 192.168.0.40 4994 21000 TCP
FlexRadio SmartLink UDP Port 192.168.0.40 4993 22000 UDP

When rebooted you have internet - and Smartlink shows as a green pass.
Leave it connected and powered on overnight and you come back to NONE and no Smartlink.

A reboot always restores the internet connection to the radio.

I *do* want to use it remotely when out of the office, sadly, I cannot at this time without someone rebooting the radio.
