I agree this needs to be updated on the client list page.  Having to drill down to the AP itself  just to the actual channel width being used is redundant.  ... View more

Hey @stevebg4,   The Client association expired is different from the Unknown reason message.    In the first case there's a few possibilities, like the Client leaving the area of coverage of the AP.   The Unknown reason, normally indicates that this has not necessarily been triggered by the AP and there might be other elements interfering with the re-association.    Make sure you try and take packet captures as well when you troubleshoot this kind of issues as they can help you understand if the disassociation is coming from the client or from the AP (and they help us too, should you contact support to get help to resolve this! 🙂 ).    Thanks!   Giacomo ...

If you are using 802.1x then you can't bypass that.   This is the guide for configure MAC based RADIUS authentication. https://documentation.meraki.com/MR/Encryption_and_Authentication/Enabling_MAC_based_access_control_on_an_SSID   In your case - you will need to create two SSIDs, one configured for 802.1x and one configured the MAC authentication.  Note that MAC authentication does not use any encryption of the data sent over the wire. ...

12Mb is considered to be the normal minimum setting to use as you can get strangeness with some chipsets especially for their initial connections if you set a higher value.   My son's HP laptop will not make a new association (after a rebuild) if you set the minimum rate at 18Mb or above, after the very first association you can then turn up the minimum bit rate without any issues (so I think HP were doing something stupid with their stack though.) I dug through every Wi-Fi equipped device that I have access to and other stuff have strange things when setting up a new connection, with Nintendo products being the most horrible so that isn't really an issue for most Meraki installs.   For reference, some won't make an initial connection if band steering is enabled, some insist upon 802.11b speeds being available for the first association, then they are happy running on 802.11g I only mention this as I am sure other devices suffer from strange behaviour too such some Zebra (Motorola) devices can't connect to a certain competitors APs for example due to DHCP options not being parsed properly, so even though the the spec says things 'should be good' reality says otherwise. ...
