I own the Pioneer VSX-1123-K and a VSX-1121-K Receivers. I have them connected to one network switch and they are all on the subnet 192.168.2.0/24. I have had this setup for several years and it has been very stable. However, I recently purchased and installed several Amazon Echo devices (sold by Amazon) and started experiencing issues with all my Pioneer receivers. In particular, I started to notice Apple Airplay cuts out about every 20-30 minutes. I also noticed HomeSeer was being disconnected by the Pioneer receivers when I lost Airplay connectivity.
In a nutshell, the Ethernet interfaces on all of my Pioneer Receivers are resetting (at exactly the same time) as a result of a UPnP/SSDP packet being sent by the Amazon Echo. I can duplicate the issue 100% of the time by simply asking my Amazon Echo to “discover devices”. This results in a UPnP/SSDP packet to be broadcast on my local LAN (it’s part of the UPnP/SSDP protocol). Unfortunately, the UPnP/SSDP packet sent by the Amazon Echo causes the Pioneer Receiver Ethernet Interface to reset. I was able to prove this by purchasing a switch that sends an SNMP trap whenever a switch port changes state. Packet captures also shows the Pioneer Receiver resets the Ethernet interface because the first packet sent after it comes back online is a DHCPDISCOVER. I tried setting a static IP, but that didn’t help (cause the Pioneer Receiver is resetting the Ethernet Interface which causes all connected devices to disconnect). I was also able to prove this by capturing packets to see the Pioneer Receiver is sending a TCP RST packet to any connected TCP client (e.g. my home automation system) prior to the Interface resetting.
If you are also experiencing this issue, please contact Pioneer support.
Possible work-around:

Possible work-around:
- Purchase a network switch that can block UDP traffic by source IP (e.g. Netgear GS108T currently $72 at Amazon).
- Connect your Pioneer Receivers to the new switch and connect the new switch to your existing network via port 1.
- Assign a static IP address to each Amazon Echo using DHCP.
- Add an IP Extended Rule to block all UDP traffic from the IP address you assigned to your Amazon Echo and assign that rule to port 1.
