Devices on different bands cannot connect to Google Home

Question

Router - RAX200&nbsp;I have 1 x 2.4Ghz and 2 x 5Ghz channels, running using Smart Connect.&nbsp;When the Google Nest connects through 5GHz-1, devices connecting through 5GHz-2 cannot cast Spotify to the hub, share with any devices on 5Gh-1, or see the Google Nest etc.It's as if devices on different bands are on a different network.Any way that devices on different bands can see each other on my Wifi? (preferred solution)Otherwise, is there any way to disable one of the 5Ghz bands without disabling Smart Connect?

What router do you have?&nbsp;
What firmware is on it?&nbsp;
What modem/gateway is the router connected to?&nbsp;

Thanks for response 🙂&nbsp;Router - RAX200Firmware - V1.0.10.140_1.0.79&nbsp;Connected to modem - Technicolor TG789vac v2&nbsp;I updated the firmware to latest tonight. I can no longer see 5Ghz connections from my router IP or through the android app.&nbsp; When my phone connects over 2.4Ghz I can't cast to the Google Nest, which is connected over 5GHz.&nbsp; After reconnecting the phone a number of times it finally connected at 5Ghz and was able to cast to the Google Nest (Signal strength at 100%, 2m from router, so not sure why it sometimes connects over 2.4).&nbsp; As stated, can't see 5Ghz devices so can't see which band any of them are connecting through.

That looks like a modem/router (gateway). Adding the RAX200 is an invitation to trouble.

Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.This explains some of the other drawbacks.What is Double NAT? | Answer | NETGEAR SupportIt may be possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router.

Sometimes it is easier to put the second router into AP mode. But that has its own drawbacks:Disabled Features on the Router when set to AP Mode | Answer | NETGEAR Support

Thanks for replies so far.&nbsp; Making progress.I was initially advised I would need the modem for connection to the internet.&nbsp; It turns out the RAX200 router can connect directly so I've removed the modem entirely.&nbsp; Rebooted the RAX200.&nbsp;I still have no clue why I can't always see devices in the house.Here is a screen grab of both my Android and my partner's iPhone connected to 5GhzThese are the devices I can cast toThese are the devices my partner can cast toSometimes I see the same as my partner although if I disconnect and reconnect to the WiFi I might get the other list.At first I thought it might be the phones connecting alternatively to 2.4 and 5Ghz and seeing corresponding devices, but the screengrabs were done while both were connected to 5Ghz, at least according to Router (as shown)Any help appreciated.&nbsp;The
