@jimsalter@fosstodon.org is this because most other devices have more strict trigger thresholds?
“Know the trigger threshold for Apple devices: The trigger threshold is the signal level (in decibel-milliwatts) at which a client begins scanning for a better connection. Mac computers use –75 dBm and iPhone and iPad devices use –70 dBm as the trigger. Therefore, for example, if you design 5 GHz cells with a –67 dBm overlap, the devices remain connected to the current basic service set identifier (BSSID) longer than you expect. When the threshold is crossed, the devices initiate a scan to find roam candidate BSSIDs for the current wireless network’s identifying name (ESSID).”

@kmh@hachyderm.io essentially, and in combination with the fact that if you use the old trick of injecting a deauth packet to force trigger roaming, they won't actually roam--they just sit there idiotically until you manually open up the SSID list and tap the SSID you were already connected to. ANY other STA I've ever tested, when deauthed like that, will just reconnect automatically. But not Apple. I can't get the APs' TX any lower than it is now. I'd have to paint the walls with lead or something.
