Setting up Chromecast on both guest wifi and main wifi

[Dan_emde]

I have a T3200M and am trying to get a Chromecast connected to both my guest network and my main network. When setting up the Chromecast I would get to connecting to wifi and sometimes it works but most of the time it does not. The few times that it works I would go to Netflix to test out streaming and would not be able to find the Chromecast, I would then go in to the Home app and it would not be able to connect to the Chromecast. Even though I had just finished setting it up and the Home app had no problem connecting. The CTV app had no problem connecting to the Chromecast. 

The Chromecast connected to my main network was working just fine. However it is now having some problems as well. I would go in to Netflix and have no problems connecting and streaming and then go in to Netflix later and it would no be able to connect. The Home app also would not be able to connect.

I also have a ASUS AT-AC68U router that I used a while ago that is not currently hooked up but was wondering if this might be a better solution...

I am looking for any help at all.

Thanks

Forgot to mention that I have a guest suite and want to keep the internet and Chromecast on separate networks for the guest and our selves.

so 2 Chromecast devices, each connected to a different SSID, and managed independently by the viewer of the TV?

That would be correct.

You might be best to create a separate subnet using an additional router for the suite. That way all traffic is separated from your network. If you are on Fibre, you could place a switch between the ONT and two routers; or you can bridge Port 1 of your main router to use for the second network.

Thanks! I'll give that a try. I will have to wait until our current guest leaves before trying it as I kind have it working, not how I want to right now, but it works.

Thanks,

Is SSID isolation enabled in the T3200?  if not enable it and see if it makes a difference,
