I just changed my WIFI device to Ubiquiti LR AP, which provides two SSID with 2.4G and 5G. I connected my Sonos 5 using the cable and Windows Sonos application can detect this Sonos 5, but when tried to reset WIFI password under advances settings. it kept failed with 'Wireless Problem Please check the name and password for your network. Ensure you are using 2.4G ', the screen shot of this error is attached here.
I am very sure my new Ubiquit AP is working as all my other devices (iPhone,iPad,TV...) are connected to there sucessfully, except my Sonos 5 speaker.
I have upgraded Sonos 5 firmware to the latest, but still no luck.
Does Sonos 5 support 2.4G password like Google1@3$$$?
Can you please assist?
