  31. .Sh NAME
  32. .Nm iwi
  33. .Nd "Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver"
  34. .Sh SYNOPSIS
  35. To compile this driver into the kernel,
  36. include the following lines in your
  37. kernel configuration file:
  38. .Bd -ragged -offset indent
  39. .Cd "device iwi"
  40. .Cd "device iwifw"
  41. .Cd "device pci"
  42. .Cd "device wlan"
  43. .Cd "device firmware"
  44. .Ed
  45. .Pp
  46. Alternatively, to load the driver as a
  47. module at boot time, place the following line in
  48. .Xr loader.conf 5 :
  49. .Bd -literal -offset indent
  50. if_iwi_load="YES"
  51. .Ed
  52. .Pp
  53. In both cases, place the following line in
  54. .Xr loader.conf 5
  55. to acknowledge the firmware license (see below):
  56. .Bd -literal -offset indent
  57. legal.intel_iwi.license_ack=1
  58. .Ed
  59. .Sh DESCRIPTION
  60. The
  61. .Nm
  62. driver provides support for
  63. .Tn Intel
  64. PRO/Wireless 2200BG/2915ABG MiniPCI and 2225BG PCI network adapters.
  65. .Nm
  66. supports
  67. .Cm station ,
  68. .Cm adhoc ,
  69. and
  70. .Cm monitor
  71. mode operation.
  72. Only one virtual interface may be configured at any time.
  73. For more information on configuring this device, see
  74. .Xr ifconfig 8 .
  75. .Pp
  76. This driver requires the firmware built with the
  77. .Nm iwifw
  78. module to work.
  79. For the loaded firmware to be enabled for use the license at
  80. .Pa /usr/share/doc/legal/intel_iwi/LICENSE
  81. must be agreed by adding the following line to
  82. .Xr loader.conf 5 :
  83. .Pp
  84. .Dl "legal.intel_iwi.license_ack=1"
  85. .Sh FILES
  86. .Bl -tag -width ".Pa /usr/share/doc/legal/intel_iwi/LICENSE" -compact

  91. .Sh EXAMPLES
  92. Join an existing BSS network (i.e., connect to an access point):
  93. .Bd -literal -offset indent
  94. ifconfig wlan create wlandev iwi0 inet 192.168.0.20 \e
  95. netmask 0xffffff00
  96. .Ed
  97. .Pp
  98. Join a specific BSS network with network name
  99. .Dq Li my_net :
  100. .Pp
  101. .Dl "ifconfig wlan create wlandev iwi0 ssid my_net up"
  102. .Pp
  103. Join a specific BSS network with 64-bit WEP encryption:
  104. .Bd -literal -offset indent
  105. ifconfig wlan create wlandev iwi0 ssid my_net \e
  106. wepmode on wepkey 0x1234567890 weptxkey 1 up
  107. .Ed
  108. .Pp
  109. Join a specific BSS network with 128-bit WEP encryption:
  110. .Bd -literal -offset indent
  111. ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \e
  112. wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
  113. .Ed
  114. .Sh DIAGNOSTICS
  115. .Bl -diag
  116. .It "iwi%d: device timeout"
  117. The driver will reset the hardware.
  118. This should not happen.
  119. .It "iwi%d: firmware error"
  120. The onboard microcontroller crashed for some reason.
  121. The driver will reset the hardware.
  122. This should not happen.
  123. .It "iwi%d: timeout waiting for firmware initialization to complete"
  124. The onboard microcontroller failed to initialize in time.
  125. This should not happen.
  126. .It "iwi%d: could not load firmware image '%s'"
  127. The driver failed to load the firmware image using the
  128. .Xr firmware 9
  129. subsystem.
  130. Verify the
  131. .Xr iwifw 4
  132. firmware module is installed and the license agreement
  133. .Xr loader 8
  134. tunable has been set.
  135. .It "iwi%d: could not load boot firmware"
  136. An attempt to upload the boot firmware image to the onboard microcontroller
  137. failed.
  138. This should not happen.
  139. .It "iwi%d: could not load microcode"
  140. An attempt to upload the microcode image to the onboard microcontroller failed.
  141. This should not happen.
  142. .It "iwi%d: could not load main firmware"
  143. An attempt to upload the main firmware image to the onboard microcontroller
  144. failed.
  145. This should not happen.
