Hi Andy,
As Phil mentioned, please make sure you have CI-V Transceive set to “ON”, and double-check it in case it got turned off by another program.
Your 705 will work over the network out of the box, with just a few changes to the menus (enable LAN, enable LAN control, set up a user and password, etc). Just route the ports through your router – and it sounds like you have done that already!
For the 7300, you’ll need a Raspberry Pi or a regular desktop computer to run wfview on, with the 7300 connected via USB. We have a page of the User Manual called “Remote Operation” that details this setup. You should also know that we are working hard on the wfview to wfview streaming audio connection code and there will be big improvements soon.
Let us know what questions you might have,
–E
