Disconnecting Chromecasts

[GreatWillmieste]

I am in a school environment with 25+ Chromecast Ultra's.  The Chromecasts are connected to ceiling mounted projectors and connected to our internal Wifi.  Since the beginning of school teachers have been reporting getting disconnected from their rooms Chromecasts often and repeatedly.  Some classes have no issues, some they will get dropped 8-10 times in a row.  Teachers are connecting from both PC's and Chromebooks, via the Chrome CAST option.  They also know not to click on anyone else's Chromecast, as that will disconnect the other teacher (we had that happen A LOT the first few weeks we had these).

I have checked Wifi strengths in each room, all are good (-60db or better).  I have rebooted AP's (access points) and switches, checked for updates on everything.  Monitoring the Wifi traffic, I am not seeing high traffic on any one AP, entire network is 1GB rated (most switches are connected to each other via Fiber).

What ideas do you all have?

Hi GreatWillmieste,

Thanks for reaching out. Please try to reboot your Wi-Fi router, affected Chromecast devices, and casting devices. Plugging it in a different HDMI port on the projector or TV might also help.

Regards,

Hey there,

It's me again. I want to make sure you're all good — how did the steps go?

Thanks,

Jennifer

Oh, I had already tried THOSE steps before posting here.

What did seem to help was running the Unfi Wifi performance scans and then manually assigning different radio channels to adjoining AP's.  I also dropped the power output on several of the AP's so that the Chromecasts were not trying to talk to the AP down the hall, through three concrete walls...instead of the one just 15 feet away through ONE concreate wall....just because it saw the other one first.

After all of that they all seem to be operating properly.
