I'd expect the most likely source of this to be one of the mac80211 code paths in mlme.c where disconnection is triggered if the current AP become unreachable. Getting a debug log from mac80211 might help in figuring out what is causing this (there seem to be number of mlme_dbg() calls before most, but not necessarily all, places where WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY is used). -- Jouni Malinen PGP id EFC895FA
