[hpsdr] Problems with direct connection PC-OpenHPSDR

[Kjell Karlsen]

Hi All.

For the first time as far as I can remember, I am not able to get in  
direct connection from a PC to an Orion MKII (and Hermes)

I am using an Intel NUC Mini PC with a i7 processor. It work perfect as  
long as the LAN connection is via a switch but when trying direct  
connection, it does not work. The strange thing is that if they have been  
connected and I just move the cable from the switch and connect directly,  
the connection is OK for around 10-20 seconds, then disconnects and after  
that it is not possible to connect.

I have had times before that I had to set a fixed IP address on the  
OpenHPSDR card to use direct connection and then there was no problem. And  
I have tried on 2-3 other PC´s, all with Win10 installed and it always  
works.

So I have concluded that there must be a setting in the NUC PC that is  
different from the others. I had problems when I first  installed Win10 on  
that PC. I had to select UEFI instead of Legacy when booting during setup  
(whatever this means, I am not a PC Guru anyway!)

Can someone lead me in the right direction?

73, Kjell
