Does the GO/AP send a Disassociation or Deauthentication frame for the first association after the Authentication frame for the second association has been sent? Or is this simply an internal issue within the GO/AP in a sense that it does not handle a sequence where STA-initiated disassociation/deauthentication is followed by a new authentication/association attempt very quickly? In either case, the real issues seems to be on the GO/AP side and this should be considered only from the view point of interoperability workaround with a deployed device as far as STA-side functionality is concerned. > Would it be okay to make this explicit deauth code conditional under a > supplicant conf variable? I don't think that that would be a good idea. The STA-initiated disassociation was needed to work around issues with some AP WPS implementations. Making this behavior configurable would mean that whoever disables this will get those earlier issues back.. I'd much rather consider changes where ieee802_1x_finished() would not issue the Deauthentication request immediately in case WPS was used (i.e., do not change behavior for other EAP cases) and instead, wait a short time for the AP to initiate deauthentication. If that does not show up within N ms, the station should still have an automatic trigger for doing the disconnection. -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
