Juerge it's not in .config because you have not enabled any wireless driver that will select it. But option is still there. just enable something like "Cisco/Aironet 34X/35X/4500/4800 ISA and PCI cards" (CONFIG_AIRO or CONFIG_IPW2100 as eerror message suggests) and you'll find CONFIG_WIRELESS=y inside .config.
I have a Atheros Communications Inc. AR5212 802.11abg NIC. Now I am using the ath5k driver for WLAN communication. In the past I used the madwifi-ng. If I activate all ATH specific options, CONFIG_WIRELESS_EXT is not set: root@thinkpad:/usr/src/linux(31)# grep -i ath .config # CONFIG_MATH_EMULATION is not set CONFIG_BT_ATH3K=m CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug" # CONFIG_MD_MULTIPATH is not set # CONFIG_DM_MULTIPATH is not set CONFIG_ATH_COMMON=m # CONFIG_ATH_DEBUG is not set CONFIG_ATH5K=m # CONFIG_ATH5K_DEBUG is not set CONFIG_ATH9K_HW=m CONFIG_ATH9K_COMMON=m CONFIG_ATH9K=m # CONFIG_ATH9K_DEBUGFS is not set CONFIG_ATH9K_HTC=m # CONFIG_ATH9K_HTC_DEBUGFS is not set root@thinkpad:/usr/src/linux(32)# grep CONFIG_WIRELESS_EXT .config CONFIG_WIRELESS_EXT_SYSFS=y If I activate CONFIG_IPW2100 I get also the CONFIG_WIRELESS_EXT option. But does it make sense, to activate the CONFIG_IPW2100 if I want to get madwifi_ng for an atheros card?
