Network goes down when using Dante and Neutrik NA2 IO DLine?

Hello!

At home we use a network for al our computers, printers, mediaboxes and other stuff like that. The network begins with an modem/router provided by our ISP called Ziggo. From this point there is an 10meter cat6 cable that goes into a wifi booster, also provided by the ISP. The wifi booster is an access point with wireless and 4 LAN connectors. One of these connectors is coupled thru an Netgear GS108PE3 switch with POE. I have connected an Neutrik NA2-IO-Dline Dante Interface to this switch because it needs the POE to work.

At the same switch i have connected my computer which runs Dante Virtual Soundcard and Dante controller. In this configuration everything works fine for a short time. Sometimes after minutes, sometimes after an hour or more and sometimes after a day the wifi booster freezes. All the internet connection, also the wifi will drop.

When i disconnect the Neutrik the internet connection come automatically back. Somethimes i need to manually restart the wifi booster. Can anybody help me out with this problem? Thank you!
