We are excited to announce that we have launched our new Hive Community! HiveNation will remain as an archive, but all new posts, discussions, and articles will be created on Hive Community. You can visit our new community at thehivecommunity.aerohive.com
That's one of the huge benefits of aerohive. The AP's balance load very well not only between AP's but also between the two frequency's 2.4GHz vs 5 GHz. So if there are too many client on 5GHz the AP it's associated with can push it to 2.4 if that is an option on the device. You can toggle that on or off in the configuration however for high capacity environments they recommend keeping it on to better balance the load. We have never had an issue with a device roaming inappropriately.
