i had an issue like this. Never proved it, but strongly suspected it to be corruption of the mesh settings over the wired lan. The cat5 (not cat5e) was flapping between 1g and 100mbit with presumably a high error rate. changed cable (run across the floor of the house as a test) and it was fine. changed switch at one end (link stopped flapping) and it was also fine. it was like there is no error checking on what comes over the wire for mesh config sync of the password. so any old rubbish was getting stored as the wifi password in one the ap903 that was having issue with its cat5. only seemed to impact the wifi password though, all the rest of the config was fine?!?!

power cycle the 903 and it'd sort itself out for a while. or just power it off so iphone/ipad would find another mesh node to use, and that was fine too. though with a weaker signal as the node was further away.

got some cat6a to run in to replace all my aged cat5. showing its age now.


forgot to add. i've also scheduled the ap903 to all reboot once a week during the early hours. but since i changed the switch the ap903 is connected via, its all been good.

I had this exact issue with the 903APs, it's something to do with the 'Fast Transition Roaming' and iOS. Enabling 802.11r on the roaming settings in the AP but setting to 'Sync over Air' rather than 'Sync Over DS' improved things but disabling the 'Fast Transition Roaming' completely is what fixed it for me.
