The second generation 88W8335/88W8310 chipsets support 802.11b/g. .Pp These are the modes the .Nm driver can operate in: .Bl -tag -width "IBSS-masterXX" .It BSS mode Also known as .Em infrastructure mode, this is used when associating with an access point, through which all traffic passes. This mode is the default. .\" .It IBSS mode .\" Also known as .\" .Em IEEE ad-hoc .\" mode or .\" .Em peer-to-peer .\" mode. .\" This is the standardized method of operating without an access point. .\" Stations associate with a service set. .\" However, actual connections between stations are peer-to-peer. .\" .It Host AP .\" In this mode the driver acts as an access point (base station) .\" for other cards. .It monitor mode In this mode the driver is able to receive packets without associating with an access point. This disables the internal receive filter and enables the card to capture packets from networks which it wouldn't normally have access to, or to scan for access points. .El .Pp The .Nm driver can be configured to use Wireless Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and WPA2-PSK). WPA is the de facto 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 .Nm driver relies on the software 802.11 stack for both encryption and decryption of data frames. .Pp The .Nm driver can be configured at runtime with .Xr ifconfig 8 or on boot with .Xr hostname.if 5 . .Sh FILES The driver needs a set of firmware files which are loaded when an interface is brought up: .Pp .Bl -tag -width Ds -offset indent -compact .It Pa /etc/firmware/malo8335-h .It Pa /etc/firmware/malo8335-m .It Pa /etc/firmware/malo8338 .It Pa /etc/firmware/malo8385-h .It Pa /etc/firmware/malo8385-m .El .Pp These firmware files are not free because Marvell refuses to grant distribution rights. As a result, even though .Ox includes the driver, the firmware files cannot be included and users have to download these files on their own. .Pp A prepackaged version of the firmware, designed to be used with .Xr pkg_add 1 , can be found at: .Bd -literal -offset indent http://www.nazgul.ch/malo/malo-firmware-1.4.tgz .Ed .Sh HARDWARE The following cards are among those supported by the .Nm driver: .Pp .Bl -column -compact "Microcom Travelcard" "MALO111" "CardBus" "a/b/g" -offset 6n .Em "Card Chip Bus Standard" Ambicom WL54CF 88W8385 PCMCIA b/g I-O DATA WN-G54/CF 88W8385 PCMCIA b/g Netgear WG511v2 88W8310 CardBus b/g Netgear WG311v3 88W8335 PCI b/g Tenda TWL541C 88W8310 CardBus b/g Tenda TWL542P 88W8335 PCI b/g .El .Sh EXAMPLES The following .Xr hostname.if 5 example configures malo0 to join whatever network is available on boot, using WEP key .Dq 0x1deadbeef1 , channel 11, obtaining an IP address using DHCP: .Bd -literal -offset indent dhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11 .Ed .Pp .\"The following .\".Xr hostname.if 5 .\"example creates a host-based access point on boot: .\".Bd -literal -offset indent .\"inet 192.168.1.1 255.255.255.0 NONE media autoselect \e .\" mediaopt hostap nwid my_net chan 11 .\".Ed .\".Pp Configure malo0 to join network .Dq my_net using WPA-PSK with passphrase .Dq my_passphrase : .Bd -literal -offset indent # ifconfig malo0 nwid my_net wpa wpapsk \e $(wpa-psk my_net my_passphrase) .Ed .Pp Return malo0 to its default settings: .Bd -literal -offset indent # ifconfig malo0 -bssid -chan media autoselect \e nwid "" -nwkey -wpa -wpapsk .Ed .Pp Join an existing BSS network, .Dq my_net : .Bd -literal -offset indent # ifconfig malo0 192.168.1.1 netmask 0xffffff00 nwid my_net .Ed .Sh SEE ALSO .Xr arp 4 , .Xr cardbus 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr netintro 4 , .Xr pci 4 , .Xr hostname.if 5 , .Xr hostapd 8 , .Xr ifconfig 8 , .Xr wpa-psk 8 .Sh HISTORY The .Nm driver first appeared in .Ox 4.1 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Claudio Jeker and .An Marcus Glocker .
