Рассмотрим быстрый способ запустить сетевую WiFi карточку производства D-Link или другой на чипе Atheros Communications.
смотрим что подключено к PCI
#ispci -v
01:09.0 Ethernet controller: Atheros Communications, Inc. AR5005G 802.11abg NIC (rev 01)
Subsystem: D-Link System Inc D-Link AirPlus G DWL-G510 Wireless PCI Adapter(rev.B)
Flags: bus master, medium devsel, latency 32, IRQ 12
Memory at df000000 (32-bit, non-prefetchable) [size=64K]

#lsmod
Нам нужен модуль ath_pci.
Если в списке его нет, устанавливаем драйвера madwifi.
#cd /usr/src #wget http://heanet.dl.sourceforge.net/sourceforge/madwifi/madwifi-0.9.3.1.tar.gz #tar xzf madwifi-0.9.3.1.tar.gz #cd madwifi-0.9.3.1/ #make #make install # modinfo ath_pci filename: /lib/modules/2.6.21.5/net/ath_pci.ko author: Errno Consulting, Sam Leffler description: Support for Atheros 802.11 wireless LAN cards. version: 0.9.3.1 license: Dual BSD/GPL vermagic: 2.6.21.5 mod_unload 486 gcc-3.4 depends: ath_hal,wlan #modprobe ath_pciДрайвера в порядке. Пробуем подключиться к какой-нибудь открытой сетке. Посмотрим что есть вокруг.

Вот и все. Для автоматической конфигурации при старте системы правим
/etc/rc.d/rc.wlan. Ищем строчку if ! $MODPROBE p80211; then
и меняем на if ! $MODPROBE ath_pci; then. В файле
rc.inet1.conf:
IFNAME[4]="ath0" USE_DHCP[4]="yes" WLAN_ESSID[4]="Golden_WiFi"
