ICOM and computer must be connected through a router with DHCP server enabled. no direct connection laptop -> icom.

You don't have to use a router. But you do need a DHCP server running on the laptop on the ethernet interface.

It's pretty easy,

1) Set a static IP on the Ethernet (not wireless) interface - I use 192.168.254.1
2) Install DHCP server (www.dhcpserver.de)
3) Configure DHCP server to listen on the Ethernet interface
4) Click on the buttons to set firewall ports and run as service
5) Connect up your ICOM and it'll get a DHCP address from the DHCP server

Then you can program everything without faults.

I use this on multiple ISPI laptops and never had an issue and never needed a router to connect the computer and ICOM to.

Thank you very much!!!
