last year wife & I bought a new samsung 43" TV for the lounge and we put the old 2012 Panasonic Viera TV in the bedroom

we have chromecast and I've hooked that up to the Panasonic TV in the becroom and I've been able to use it fine to watch concerts from youtube and watch rugby games streaming from our Macbook...etc...

however, last night I went to watch something on the panasonic TV via chromecast / macbook, but when I went to cast it, the chromecast I set up was not available and instead it wanted to select our new Samsung TV to cast it on.... there wasn't even a drop down box where I could select where to cast it to - the Samsung TV was the only option.

I've checked the chromecast is plugged in and connected properly so it's all good there,so I don't understand why it wanted to cast to the Samsung TV only, because it's never come up with the Samsung TV as an option to cast to before - even though we've had the Samsung TV about 8 months

does anyone know how to fix this so that I can just cast it to the Panasonic TV only via chomecast?

any help would be appreciated

I've occasionally had a chromecast not be available to select. Usually a power cycle of the CC is enough to bring it back to life. Another option is to reset the CC, and go thru the setup again.

Apart from a reboot, could it be that you have 2.4Ghz and 5Ghz wifi and the device you are casting from is on a different frequency to the chromecast?

e.g your phone/Tablet is connected to the 5Ghz wifi on your home network and the chromecast is connected to the 2.4Ghz wifi.

Ensure the tablet/phone and chromecast are on the same frequency.

ok thanks for that - I think that might be the issue.

Vodafone sent us some Deco broadband / fibre units and I set them up about 6 weeks ago and now our WiFi name / code is different to what it was when we set up the chromecast

I don't know how to 'reset' the chromecast though.... i'll have a look at it and see if I can figure it out

Many thanks

Google Home app will sort you out. It should be able to find it and reset to factory defaults. If its a GEN 1 or 2 then there is a factory reset button on the device hold it for about 10sec.

If the deco set is doing nat onto the ISP router then that will stop things on the 2 networks seeing each other properly. Ive not set one of those up to know what options it has as far as nat or not when installing, but that is the first thing I would check for.
