Since upgrading kernel-2.6.23.15-137.fc8 to kernel-2.6.24.3-12.fc8 the parameter ieee80211_regdom=64 for module mac80211 isn't available anymore. This is necessary to use wireless channels which else aren't available. While using the new kernel the following command fails: modprobe mac80211 ieee80211_regdom=64 Modinfo also doesn't show the missing parameter anymore: [root@localhost ~]# modinfo /lib/modules/2.6.24.3-12.fc8/kernel/net/mac80211/mac80211.ko filename: /lib/modules/2.6.24.3-12.fc8/kernel/net/mac80211/mac80211.ko license: GPL description: IEEE 802.11 subsystem description: Simple rate control algorithm license: GPL license: GPL author: Mattias Nissler author: Stefano Brivio description: PID controller based rate control algorithm depends: cfg80211 vermagic: 2.6.24.3-12.fc8 SMP mod_unload 686 4KSTACKS parm: ieee80211_default_rc_algo:Default rate control algorithm for mac80211 to use (charp) The old module has this parameter: [root@localhost ~]# modinfo /lib/modules/2.6.23.15-137.fc8/kernel/net/mac80211/mac80211.ko filename: /lib/modules/2.6.23.15-137.fc8/kernel/net/mac80211/mac80211.ko license: GPL description: IEEE 802.11 subsystem description: Simple rate control algorithm license: GPL license: GPL author: Mattias Nissler author: Stefano Brivio description: PID controller based rate control algorithm depends: cfg80211 vermagic: 2.6.23.15-137.fc8 SMP mod_unload 686 4KSTACKS parm: ieee80211_regdom:IEEE 802.11 regulatory domain; 64=MKK (int) parm: ieee80211_japan_5ghz:Vendor-updated firmware for 5 GHz (int) parm: ieee80211_default_rc_algo:Default rate control algorithm for mac80211 to use (charp)
Ah, sorry about that. The mechanism for changing that has changed upstream. You will need to get rid of this line in /etc/modprobe.conf: options mac80211 ieee80211_regdom=64 And add this instead: options cfg80211 ieee80211_regdom="JP" Unfortunately I don't see any reasonable way to hack around this to preserve the old mac80211 module option for F8. I'm sorry.
