Remote PC randomly goes offline in Chrome Remote Desktop

[Billyjack5]

Running into odd issue that I'm trying to narrow down. I have 1gb fiber that runs from the ONT to a Centurylink C4000XG modem/router. From the Centurylink router, two of the ports are connected by Cat6 to two unmanaged POE switches. One of the switches is a 10 port POE switch that powers 8 cameras and the other is a 24 port Netgear switch, which is connected directly to the PC that runs Blue Iris. Between the two switches I run 22 cameras.

I use Google Remote Desktop to access the BI PC that is connected to the 24 port Netgear switch. For reasons that I can't ascertain, the PC will alternate between being online and offline in the Remote Desktop app. When it shows online in the app, I can remote into the PC and control it as expected. When offline, I obviously can't remote in. None of the 22 cameras ever go offline, just the connectively between the PC and the device I'm trying to remote access the PC from. I have the wifi adapter on the PC disabled, so it's just a LAN connection between the PC and the switch.

Anyone have any ideas of settings I should try? I started using Splashtop for comparison purposes and the behavior is the same with that program--online sometimes and offline others.

The 10 port POE switch is passing thru your router to get to the 24 port Netgear switch to get to the BI PC, not recommended.

Try moving the 10 port's cable from the router over to a port on the Netgear (if I understand your current schema). IOW, camera video shoud not pass thru the switch portion of a router to get to the BI server.

Althought that modem/router is spec'd with gigabit LAN ports I still would avoid it.

Thanks for the response. The 10 port POE switch separately connects to a different port in the Century link router and isn't between the router and the 24 port switch. For our purposes, it goes Centurylink router via cat6 to the 24 port unmanaged switch, with the 24 port switch then being connected to the Blue Iris PC LAN adapter.

That still sounds to me like the 10 port POE switch is going thru the router (The 10 port POE switch separately connects to a different port in the Century link router and isn't between the router and the 24 port switch) So either it is, or you left a word out in that sentence?

Regardless we have seen weird things in some systems if the cameras are not completely isolated via VLAN or dual NIC.

For kicks, unplug the router and see if BI still sees all your cameras. We have seen instances where for whatever reason the router was attempting to route even though the cameras and BI computer were all connected to the same switch and should have never tried to do anything with the data.

+1^^^.
Yeah, that's how I understood it when I read "From the Centurylink router, two of the ports are connected by Cat6 to two unmanaged POE switches.
