Not All Chromecasts are Visible

I setup 32 Chromecasts in a school building and put them as well as the teachers Chromebooks all on the same VLAN. The problem I'm having is that only 8-13 are visible from the Chrome cast tab. For the ones that aren't working, I can see them connected in the wifi controller as well as ping them from the devices that aren't able to cast to them. Has anybody else had luck getting a lot of Chromecasts to all work at once in an enterprise environment?

Are you running instant or controller-based APS?

Re: Not All Chromecasts are Visible

We're running a 3600 series controller and 105/205 AP's in your typical 1AP per classroom setting with the power dialed back. When I got to work this morning, I checked a few Chromecasts that were unable to be cast to yesterday and they were working fine. All other chromecasts are currently offline though since staff haven't came in and powered there projectors on yet so the traffic on the Chromecast SSID is very light right now.

Okay.  The "autoassociate" checkbox in Airgroup will only allow devices to "see" chromecasts that are on the same AP or on a neighboring AP.  Check your Airgroup configuration to ensure that is not the case.

Re: Not All Chromecasts are Visible

I see the auto-associate drop down box under the Airgroup groups, but it's empty. If I click on it, I see AP-Name, AP-Group and AP-fqln as choices. When this problem starts showing it's face, I can move around anywhere in the building and cast to any of the selectable Chromecasts in the building so it doesn't seem to be a case of only seeing Chromecasts attached to certain AP's. When testing yesterday, I was verifying that the casting device and the Chromecast that wasn't viewable were connected to the same AP, SSID, VLAN, etc.

Re: Not All Chromecasts are Visible

What version of ArubaOS are you running and what model Aruba Controller do you have deployed?

You could be running into this issue:

Screenshot 2019-08-16 at 08.59.42.png

Issue 133436 is reported as fixed in 6.5.4.0.

Issue 147369 is reported as fixed in 6.5.4.0, internally as well

 

If you have a Window, I would (1) backup flash (2) copy it off (3) Upgrade to the latest 6.5.x.x to see if it fixes it.  You can also open a TAC case to get more specific advice.

Re: Not All Chromecasts are Visible

I might be out of luck as it appears that 6.4.4.x is the latest supported release for the 3600 series controller.
