Can't Cast to Nest Audio

[Davy123]

I have installed a Google WiFi mesh system. Works very well with my Chromebook, Pixel phone.

However, when I try to cast from W10 Google Chrome browser to a Google Nest Audio, the cast searches for devices and then reports no devices found. The desktop Spotify app does not display any devices to cast to.

If I do the same thing from my mobile phone then the phone finds the Google Wifi point and will cast to it.

I have tried restarting Google Chrome browser and Windows 10 and ran Windows 10 in admin rights; but no improvement.

I have factory reset the puck and then re-added it in Google Home but no improvement.

Any more ideas anyone? Is this a W10 problem?

How have you connected your PC? Not to the Google/ Nest Wifi guest network I hope? And Windows network profile is not set to public/ not allowing you to communicate with other LAN devices?

Olavrb, thanks for your reply.

I can confirm that:

Not using the guest network, network is ‘private’

‘Network Discovery’ and ‘Automatic Setup of Network-Connected Devices’ are enabled

Just so you don't think this has something to do with Windows itself, I have no problems seeing and connecting to my two Google Cast speakers (Sony SRS-HG1) from my Windows laptop. Rocking 2x Nest Wifi routers in wireless mesh, speakers connected to the primary one (<1m away), PC to the mesh node. I reserve the first 20 IP addresses for static IPs (as in reserved IP), for devices such as my NAS running Plex, but also Google cast stuff.

Other things I can think of:

• You have no other access points in your home? Like a ISP router? Your PC is for sure not connected to that one? Could be NAT then.
• Your PC and Nest Audio has DHCP enabled and gets IP addresses in the same subnet range? 192.168.86.0-255 by default for the primary network.
• Have you tried while PC is wired to the Nest Wifi?
• Have you tried from a different Windows PC?

Olavrb, thanks for putting so much into that. I have been doing some experiments and find that it all comes down to whether I am using my ISP's Wifi router or Google Wifi. So I have created an new post 

Devices Dont Cast on Google WiFi 

and so would like to close this post. 

Many thanks
