Hi Community!
I'm using LuCI openwrt-23.05 branch (git-24.086.45142-09d5a38) / OpenWrt 23.05.4 (r24012-d8dd03c46f) and I cannot update lists of the available software.
With the Google Home app, I can configure the Google Chromecast 3. Geneneration and, in particular, allow Wi-Fi access, but I cannot add the Google Chromecast as a device in the Google Home app because the Google Chromecast could not be found.
The smartphone and the Google Chromecast are in the same Wi-Fi network and in the same subnet.
How is it possible for me to use the Google Chromecast 3. Generation with OpenWrt, in particular to add it as a device via the Google Home app?
Thanks for your assistance!
You say you use the same wifi, but I recently noticed you have to be on the same SSID as the Google device, for it to be found, when adding.
Can't blame Openwrt for it though.

This normally has nothing to do with OpenWrt, it let’s take a look at your config to make sure you don’t have something that would specifically cause issues.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
The router will tell you ?

It's a wireless clients, so I guess where those are listed ?
Sae-mixed is a terrible choice, change it to wpa2 or wpa3, it could be the reason why discovery is failing.

There is a lot going on here that doesn't look right...
Remove the last 2 lines of this section:
Where is the 10.2.0.0/24 network?? I don't see it in your config... is it upstream? This is relevant for your DNS:
Why is wan6 populated with IPv4 entries?
Do you want your wlan2g network to be on a different subnet than your main lan? Also, the radio devices should never be specified in the network file... that should be removed:
This doesn't belong...
Most of the time, 40MHz width (or greater) are used for 5G. Why are you using a 20MHz channel width?
As @frollic pointed out, don't use sae-mixed. use either WPA2 or WPA3, not mixed. But more critically, you have the isolate option enabled... if this is the network that you are trying to use for your Chromecast, it will not be able to talk to any other wifi devices. Remove the isolation.

You say you use the same wifi, but I recently noticed you have to be on the same SSID as the Google device, for it to be found, when adding.
Yes, the smartphone with which I want to set up and connect the Google Chromecast and the Google Chromecast use the same BSSID of the WLAN controller.
Switching to WPA3 means that the Google Chromecast 3rd generation cannot find the Wi-Fi network. Switching to WPA2, on the other hand, resulted in the Google Chromecast being able to find the Wi-Fi network, but the Google Home app is still unable to connect to the Google Chromecast.

config interface 'wan'
option device 'wan'
option proto 'dhcp'
option peerdns '0'
list dns '10.2.0.1'
I don't know! And I don't know where I can configure this.
I personally would just edit the config file directly using the vi text editor. However, there is probably a LuCI web interface control for this in the Network > Interfaces > Devices.

Or, to get rid of all the issues, reset, then rename the wifi, set password and encryption, leave everything else as it is.

config wifi-iface 'wifinet1'

option mode 'ap'
option ssid 'XXXXXXXXXX'
option encryption 'sae-mixed'
option key 'XXXXXXXXXX'
option network 'wlan2G'
option isolate '1'

Isolation is deactivated. The connection to the Google Chromecast with the Google Home app now works. Thank you very much for your help!

glad that fixed the problem.
