I'm trying to understand how the device list works. At first I thought it was based on the routers ARP table and when a MAC aged out, it was gone. At least that's how it seemed to work in 1.13 by my recollection. Now under 1.15, when a wireless client connects, it shows up under eth1 complete with RSSI and quality but then after disconnecting, it seems to linger around as bro obviously without the RSSI, I think for the duration of the lease. Why does it linger around long after it has disconnected? I don't recall 1.13 doing that.
