NAME

SYNOPSIS

DESCRIPTION

These are the modes the bwfm driver can operate in:

BSS mode

Also known as infrastructure mode, this is used when associating with an access point, through which all traffic passes. This mode is the default.

Host AP

In this mode the driver acts as an access point (base station) for other cards.

The bwfm driver can be configured to use Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and WPA2-PSK). WPA is the current encryption standard for wireless networks. It is strongly recommended that WEP not be used as the sole mechanism to secure wireless communication, due to serious weaknesses in it. The bwfm driver relies on the software 802.11 stack for the WPA handshake. Both encryption and decryption of data frames are handled by the firmware.

The firmware automatically selects the transmit speed and the channel depending on the received signal strength.

The bwfm driver can be configured at runtime with ifconfig(8) or on boot with hostname.if(5).

FILES

EXAMPLES

The following hostname.if(5) example configures bwfm0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:

nwid mynwid wpakey mywpakey
dhcp

The following hostname.if(5) example creates a host-based access point on boot:

mediaopt hostap
nwid mynwid wpakey mywpakey
inet 192.168.1.1 255.255.255.0
