Issue with XR500 and S8000 Gaming Switch

Question

Hello All!I am having an issue with my recently upgraded home network. I upgraded my old router to the XR500, S8000 and a Powerline 2000 converter to help reduce lag and combat the issue we have with our ever growing number of WiFi devices. We have a total of 5 Lifx Smart Lightbulbs, a smart power socket, a HomePod, 2 Macs, 3 Iphones, an IPad and an old PS3 all connected via WiFi. I have the S8000 switch connected to the router running the hardwire for the Xbox One and Apple TV. The final part is ports 3 and ideally 4 need to run to a power line adapter to get the signal to my office upstairs for the PS4 and my Gamimg PC. The network runs fine, albeit a little slower speeds to all my devices in general, but the issue arises when I try to connect the Ethernet cable for the Gaming PC. As soon as I connect said cable, the entire network crashes and causes the router to reboot.I know we have a ton of devices on our network so I am trying to determine if the issue is stemming from the hardware not being able to handle the load, in which case I’ll upgrade to the XR700, or if it is a setting that is wrong somewhere.Thank you all in advance for the help and any other info you may need just ask!Thanks,Kyle

Is from my post that the netgear lady responded to.
if all of the ports being used and their corresponding port LEDs are fast blinking blue, it means that the S8000 switch detected a network loop. As reference, read pages 6-7 of the Nighthawk S8000 user manual here&nbsp;about the LED descriptions.&nbsp;
Detect a Network LoopWhen a network loop occurs, the switch, and possibly the router to which the switch is connected, could become very sluggish or traffic on your network could come to a halt.By default, loop detection is enabled on the switch. (You cannot disable it.)If the switch detects a network loop, all port LEDs for the ports that are being used blink blue fast.This visual warning allows you to determine which ports are involved in the loop and remove the loop
but no she did not tell me how to fix it anyways random thought I did read somewhere a very long time ago in the xr500 forum that some one was having a similar problem with there gaming pc crashing there router . The guys answer was that he opened his computer case and the Lan Card was not all the way pushed into the pci slot. I dont know if thats worth looking at or if your lan is built into your motherboard.

What FW is currently loaded on the router?
What ist he MFr and model# of the ISP modem it's connected too?
&nbsp;
Does the network still crash if you connect the Game PC directly to the router? 
Swap LAN cables between PC and switch? Use good quality LAN cabling. CAT6 recommended.
Try different ports on the switch?
What is the Mfr and model# of the network adapter in the game PC?
Remove the PLs from the network and test?
&nbsp;
Total of 15 devices? My XR450 handles close to 30 devices, thought I don't have the S8000 switch. I use other switches. Several of those all connected.

I would remove the PL adapters and then test the system.

I had that problem on my switch ( lights blinking fast ) I have that same switch when i talked to netgear they said it was a network loop and linked me some article.&nbsp;

Appreciate the comments and the help! In the end, the issue ended up simply being the second Ethernet cable being plugged into the Powerline Adapter. Apparently the PL Adapter doesn’t run a separate line for each input and output so the second cable was causing a network loop. I plan on testing with the switch to see if the PL Adapter can accept an aggregate coming from the switch. If nothing else the entire network now runs fine so once again thank you all for your help!
