Only one virtual interface may be configured at any time. .Pp This driver requires the firmware built with the .Nm iwifw module to work. For the loaded firmware to be enabled for use the license at .Pa /usr/share/doc/legal/intel_iwi.LICENSE must be agreed by adding the following line to .Xr loader.conf 5 : .Pp .Dl "legal.intel_iwi.license_ack=1" .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh HARDWARE The .Nm driver supports the following wireless network devices: .Pp .Bl -bullet -compact .It Intel PRO/Wireless 2200BG MiniPCI Network Connection .It Intel PRO/Wireless 2225BG PCI Network Connection .It Intel PRO/Wireless 2915ABG MiniPCI Network Connection .El .Sh FILES .Bl -tag -width "/usr/share/doc/legal/intel_iwi.LICENSE" -compact .It Pa /usr/share/doc/legal/intel_iwi.LICENSE .Nm firmware license .El .Sh EXAMPLES Join an existing BSS network (i.e., connect to an access point): .Pp .Dl ifconfig wlan create wlandev iwi0 inet 192.0.2.20/24 .Pp Join a specific BSS network with network name .Ar my_net : .Pp .Dl ifconfig wlan create wlandev iwi0 ssid my_net up .Pp Join a specific BSS network with 64-bit WEP encryption: .Bd -literal -offset indent ifconfig wlan create wlandev iwi0 ssid my_net \e wepmode on wepkey 0x1234567890 weptxkey 1 up .Ed .Pp Join a specific BSS network with 128-bit WEP encryption: .Bd -literal -offset indent ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \e wepmode on wepkey 0x01020304050607080910111213 weptxkey 1 .Ed .Sh DIAGNOSTICS .Bl -diag .It "iwi%d: device timeout" The driver will reset the hardware. This should not happen. .It "iwi%d: firmware error" The onboard microcontroller crashed for some reason. The driver will reset the hardware. This should not happen. .It "iwi%d: timeout waiting for firmware initialization to complete" The onboard microcontroller failed to initialize in time. This should not happen. .It "iwi%d: could not load firmware image '%s'" The driver failed to load the firmware image using the .Xr firmware 9 subsystem. Verify the .Xr iwifw 4 firmware module is installed and the license agreement .Xr loader 8 tunable has been set. .It "iwi%d: could not load boot firmware" An attempt to upload the boot firmware image to the onboard microcontroller failed. This should not happen. .It "iwi%d: could not load microcode" An attempt to upload the microcode image to the onboard microcontroller failed. This should not happen. .It "iwi%d: could not load main firmware" An attempt to upload the main firmware image to the onboard microcontroller failed. This should not happen. .El .Sh SEE ALSO .Xr iwifw 4 , .Xr pci 4 , .Xr wlan 4 , .Xr wlan_ccmp 4 , .Xr wlan_tkip 4 , .Xr wlan_wep 4 , .Xr networking 7 , .Xr ifconfig 8 , .Xr wpa_supplicant 8 .Sh AUTHORS The original .Nm driver was written by .An Damien Bergamini Aq Mt damien.bergamini@free.fr .
