Have google Wifi router in house and 2 networks normal and guest...Google devices cameras and nest hub connected to Guest network...I have office in seperate building 2 metres from my house and i have a Google wifi point in here to boost signal. My problem is Google tv Chromecast that is located in office seperate building can only be found when im in the kitchen of my house, it cant be found when in offfice...and the Nest Hub(located in kitchen of house) can only be found when in the office im so confused(they are not named incorrectl, i have reset chromecast to factory settings and reinstalled it in the office, but i can only find it for casting when i return to my house...Can anyone asvise what i can do i have several cameras etc and want to avoid reseting,  evrything in google.home if possible any advice appreciated. I use andorid and wife uses Apple and she is experincng same issue as me so it must be something on network settings?

Devices connected to your primary Wi-Fi network cannot communicate with devices on your guest Wi-Fi network by default, that's a security feature and by design. Normally, you would connect your all your Google devices to your primary Wi-Fi network, not the guest network.

Hi David, thanks for taking time to respond,  all my devices google related are on guest network in my house and the office, that way guests can cast etc...my issue is that i have to be 4 metres away from chromecast tv device thats physically in my office a seperate building before its recognised, and vice versa when im in office 4 metres away from physical device Nest Hub,  this is located in kitchen of my house) i can only cast to it when im in office...not sure if that offers any further help to problem im experiencing...

You don't need to do that, you can have them connected to your primary network and go in the guest Wi-Fi network settings in the Google Home app to share those devices with devices connected to your guest network.

What's the layout of your Wifi network? Is it all Google Wifi points? Are you using any other non-Google repeaters or extenders? Does the mesh test show good connectivity?

David sorry for delay, i had exhausted everything today removing cameras and nest hub and chrome tv and adding to home again and still no change, eventually i reset the wifi-point in the office and Chrome was now available in office to cast as well as house....so thankfully all is good now, good old relaible IT advice " Plug it out and plug it back in" 🤣 thankfully worked wish id have thoughy of it at the start, i did reset router at start but not wifi point in office....thanks for your responses...
