I can confirm the following set up will work (I just did it yesterday for my home studio and it's working great for my needs) provided you already have a WiFi network and router available, e.g. like at home.
Using a TP-Link TL-SG1005P PoE switch. With this set up, my iPad with Rig Manager installed connects with no issues to the KPA and remote works perfectly as well.
Works great for home studio needs but of course not suitable for live use.
