http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch13_:_Linux_Wireless_NetworkingAfter physically installing your Linux-compatible NIC, you need to configure your NIC's IP and wireless settings before Wireless Tools works.
After you use the ifup command the NIC becomes active, but it will not function correctly as its wireless settings haven't been configured yet.
Как да разбера, кой модул е за wireless-a?
Моята антенка е usb, като напиша lsmod тя изкача най-отгоре:
Module Size Used by
arc4 2064 2
ath9k_htc 59461 0
ath9k_common 1906 1 ath9k_htc
ath9k_hw 396294 2 ath9k_common,ath9k_htc
ath 19419 3 ath9k_common,ath9k_htc,ath9k_hw

cfg80211 459335 3 ath,mac80211,ath9k_htc
rfkill 15971 2 cfg80211
lsmod, lsusb, lspci са основните инструменти.
lsusb:
Bus 002 Device 003: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n
Значи антената ми използва ath9k_htc. Един прост поглед на последните попълнения в dmesg ми изкача директно и антената и заредения firmware

До преди две години plug and play го нямаше и си инсталирахме всички драйвъри от сорс код.
Ndiswrapper и compat драйвърите са последния ти шанс, ако вече нищо не проработи.
