I am trying to control my TS-590S remotely with the Kenwood ARHP software. I have opened the two ports on my router and excluded the programs from Windows firewall. I do not have any other software that may prevent these ports/software from running. The host PC is my desktop and I am using my laptop for the remote site. Everything works fine when I'm on my home wifi network. It's when I use a different internet connection other than my home's that it won't connect to either the ARVP-10H or ARHP-590 software. I have verified that I am using the correct IP address with the "ipconfig" command and using a Linksys router. Has anyone experienced anything like this? I know there are other ways to remote control this radio, but I would really like to use the Kenwood software since it is very simple to use...when it works. Thanks in advance.
