Some smartphones do not see SSIDs

[Flamengo19]

Good afternoon people.

See if anyone can help me. I have a network that I climbed these days with 25 MR34. There are some smartphones that do not find any of these APs.

I suspect it can only be the endpoint, since I have 3 dozen connected endpoints.

What can I check in the management environment and what can I do on the endpoint side?

I appreciate the opportunity within the community.

Hi @Flamengo19 

Have a look under Wireless Health as a starting point.

What happens if you fire up a test SSID and tweak the data rates and protocols?

Check your band selection config, for those SSIDs.   (Wireless > Access control)    If they are set to 'Dual band operation with Band Steering' try 'Dual band operation (2.4 GHz and 5 GHz)'.   Some devices use passive scanning, which can cause issues like this  (see the end of this doc:  https://documentation.meraki.com/MR/Radio_Settings/Band_Steering_Overview )

Im with @GreenMan on this

Another option is that you somehow disabled the UNII-1 channels and that this clients only support UNII-1

 The select option is Dual band Operation with band steering with can see.

You should try dual band operation.

However you have to check your rf profile. That one is leading.

Yes. 

I did a factory reset on the APs. The 2.4Ghz frequency was disabled. Only endpoints that work at 5Ghz were able to connect.
