mac80211 is a module - I learned long ago to make as modules everything that can work as a module :-) Some more info I omitted from the original post: the driver I use is the in-kernel iwl3945 (part of iwlwifi) iwl3945-ucode is installed As far as I can tell, everything I should have done according to that page and to http://www.gentoo-wiki.com/Iwlwifi has been done. Working purely from a techie's gut feel here (i.e. no evidence whatsoever), this behaviour looks like what I might get from the following circumstances: - a register in the card is not being properly initialised by the firmware, sometimes a bit is 0 sometimes a 1 at random and the results are not determined - there's a module option that I missed when reading the source comments - a weird race condition at early boot, results are pot-luck - my hardware is busted But I've run out of ideas on how to falsify these theories :-( -- alan dot mckinnon at gmail dot com
