'Troubleshooting' band-steering?

    Is there a way to debug / troubleshoot or simply look further into the band-steering process?

     

    One of our customers is mentioning that often users that are capable do not seem to connect to the 5GHz network and get stuck in 2.4GHz mode.

    Checking with "show ap band-steering-clients" does show the mac-address so the client is indeed capable.

     

    Currently band-steering is only set to prefer-5GHz.

    What would Force-5GHz do? Does this mode simply not allow a capable client onto 2.4GHz?  How does it detect who is capable anyway? Is it simply a list of who has been connected to 5GHz before?

    There is some information on the different modes in the 802.11n VRD (http://www.arubanetworks.com/vrd). Force 5 GHz is going to do exactly what the name says and force the client to move. Before you do that you might want to check your coverage and make sure that you have equal coverage in 5 GHz and 2.4 GHz. If the client can only see 2.4 then it is going to stay there. The other thing that could be happening is your device driver may really like 2.4, that's common in older drivers and with the setting your on if the device won't move we will let it stay on 2.4.
