Hi @michaelweku

Welcome to the Sonos Community!

Connecting to hidden SSIDs is definitely supported, so I’m not sure what’s going wrong for you. I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I’m with the others though - there’s not a lot of point in doing so as it is easy enough to circumvent the hiding; anyone who knows enough to hack their way onto your network will not be stopped by hiding the SSID.

I hope this helps.

I’ve seen that too, especially if you have multiple stored networks it can connect to (and defaults back to a separate SSID). I made sure to delete all other eligble networks and verified the mobile controller is in the correct subnet after reconnecting.

There’s no assoc or auth logs that the speaker attempts to connect so I’m pretty certain this is a model specific behavior.

Within seconds of unhiding SSID:

<NOTI> |stm| Assoc success @ 20:12:52.410340: c4:38:75:77:xx:xx (Speaker): AP 10.xx.xx.xx-9c:1c:12:82:xx:xx-SR18-AP225

I’m assuming these speakers utilize the wpa_supplicant component and my guess is that the wpa_supplicant.conf is configured with ‘scan_ssid=0’ which scans for the SSID using a broadcast Probe Request frame for visible networks. ‘scan_ssid=1’ on the other hand uses directed Probe Requests and will allow the speakers to connect to hidden networks.

If the above is true I’m clueless as to why that only applies to the One SL speakers (and possibly others except the ones I have tested).
