I've had a deco system for a few years now. I recenlty upgraded to PX50's. I reconnected everything the way it was before. Since then we have network interruptions - it doesn't drop, but gets really slow for a few minutes and then returns. If we are on video calls (which we do often), it freezes, we get a 'poor network quality' message and then it returns to normal. I can't figure out the reason for this - obviously something is randomly interrupting something, but how do I figure out what it is?

Thanks
