I have the same issue, some of the clients show up tagged as LAN instead of showing up which AP they are connected to. I am unable to troubleshoot wifi issues for various devices because I can't see their current connection strength and which AP they connect to. I live in a 4-level building with individual eap 225s/245 in each levels. Signal strength is significantly reduced from each level because of concrete floors but strong enough that it permeates through that clients can connect to a weak signal despite having Band-Steering, Force-Disassociation and Fast-Roaming enabled.
