I got a new Sonos Port to replace an existing (and working) CONNECT:AMP. Going through the setup, it fails when trying to connect to WiFi. It says it must be 2.4GHz, despite this page clearly saying Port works with 5Ghz: https://support.sonos.com/s/article/126?language=en_US
So, I logged in to my router, turned off the 5Ghz radio and restarted. I confirmed on my phone that I’d reconnected to 2.4Ghz. However, when I try to set up Port again, I get the same message: unable to connect to WiFi, and a warning that it must be 2.4Ghz.
Not sure where to go from here.

Sonos Port will not connect to WiFi - says network must be 2.4Ghz (which it is...)

Seems odd, for sure.
I’d start troubleshooting by physically connecting the Port to the router with an ethernet cable first, and see if it connects. Once I’ve established that, I’d test further by removing that ethernet cable, and see if it is still connected. That would tell me if there’s an issue with the wifi card in the Port. If it doesn’t connect while on wifi, and only with the ethernet cable, I’d then submit a diagnostic and call Sonos directly.
