If you’re trying to use wpa_supplicant as the wireless network manager, you probably faced how to configure it. Configuring the wireless manager is quite simple, but you should set the proper driver. If your driver is Intel Centrino Advanced N model, probably the driver’s name announced by the kernel is iwlwifi. Anyway, you can also see which wireless interface card is yours by typing:
# lspci | grep network
Suppose your card is an Intel Centrino Advanced N 6235, so when editing /etc/conf.d/net file, type:
modules_wlan0="wpa_supplicant" wpa_supplicant_wlan0="-Diwlwifi" config_wlan0="dhcp"
If you don’t have any idea how the driver name is, you can search on Google by typing, maybe, the card name or you can also use the kernel log message by typing:
# dmesg | grep Radio
It should appear something like this:
[ 17.494658] iwlwifi 0000:01:00.0: L1 Enabled; Disabling L0S [ 17.501554] iwlwifi 0000:01:00.0: Radio type=0x2-0x1-0x0 [ 17.892321] iwlwifi 0000:01:00.0: L1 Enabled; Disabling L0S [ 17.899225] iwlwifi 0000:01:00.0: Radio type=0x2-0x1-0x0
Do not confuse the wireless card name with the wireless driver name. The wireless driver name is announced by the Linux kernel and you can see it by using dmesg command.
Hope I helped you,
