This patch addresses an issue specific to Apple devices experiencing a wireless
disconnect when trying to associate with either 2.4Ghz or 5Ghz wifi of a
Linksys WRT1900AC router.
Apple devices (MacBooks running Mac OS X 10.10.x Yosemite in particular, but
there may be others), appear to re-auth/re-associate within approximately 25
seconds of initially associating.
Evidence of this can be seen by the presence of an entry similar to the
following in the Apple system logs;
MM/DD/YY HH:MM:SS.sss AM kernel[0]: wl0: Roamed or switched channel,
reason #8, bssid xx:xx:xx:xx:xx:xx
The Marvell wifi driver doesn’t generate a NL80211_CMD_FRAME_TX_STATUS event on
transmitting a response to auth and/or reassociate requests. Thus, the
respective callback handler functions (in hostapd’s ieee802_11.c) never get
driven, ultimately leading to the problem.
The patch causes a TX_STATUS event to be generated for auth and reassociate
request’s responses, in addition to associate request’s responses.
