Matter working only on 2.4GHz and not on 5GHz (CON-1424) #1162

Hi,

While testing my product, I encountered an issue connecting my Matter device to Alexa. Since I also have a Google Home, I tried using that and encountered the following problem:

"Connect your smartphone to your main 2.4GHz network, if available. Most Matter-enabled devices cannot yet connect to a 5GHz network."

My device is onNetwork and receives WiFi credentials from our app. Both Alexa and Google Home are connected to the 5GHz WiFi, and my phone also connects to the 5GHz WiFi. The pairing doesn't work unless I use another router without 5GHz; in this case, it uses 2.4GHz, and everything works fine.

Can you help me understand how to face this issue? Am I forced to change the router settings?

Thanks, Fabio

@FMistrorigo All our SoC are with 2.4 GHz and can't connect to 5 GHz wifi networks. You will have to use the AP which supports 2.4 GHz network.

Am I forced to change the router settings?

I think, yes. If the AP is dual band, you can create the 2.4 GHz network with the same SSID, and it works. (In our tests this worked seamlessly).
