Intel 3945ABG Wireless LAN IEEE 802.11 driver
To compile this driver into the kernel, place the following lines in your kernel
Alternatively, to load the driver as a module at boot time, place the following
driver provides support for the Intel
3945ABG Wireless network adapter. The driver supports
mode operation. Only one virtual
interface may be configured at any time.
driver can be configured to use Wired
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
driver offloads both encryption and
decryption of data frames to the hardware for the CCMP cipher.
This driver requires the firmware built with the
module to work.
driver can be configured at runtime

- wpi%d: could not load firmware image '%s'
- The driver failed to load the firmware image using the
subsystem. Verify the
firmware module is installed.
- wpi%d: %s: timeout waiting for adapter to initialize, error %d
- The onboard microcontroller failed to initialize in time. This should not
- wpi%d: %s: could not load boot firmware
- An attempt to upload the boot firmware image to the onboard
microcontroller failed. This should not happen.
- wpi%d: device timeout
- A frame dispatched to the hardware for transmission did not complete in
time. The driver will reset the hardware and continue. This should not
- wpi%d: scan timeout
- Firmware scan command response was not received in time. The driver will
reset the hardware and continue. This should not happen.
- wpi%d: fatal firmware error
- The onboard microcontroller crashed for some reason. The driver will reset
the hardware and continue. This should not happen.
- wpi%d: RF switch: radio disabled
- The hardware switch controlling the radio is currently turned off. Data
transmission is not possible in this state.
- wpi%d: can't map mem space
- The driver was unable to map the device registers into the host address
space. This should not happen.
- wpi%d: can't map interrupt
- The driver was unable to allocate an IRQ for the device interrupt. This
should not happen.
- wpi%d: can't establish interrupt, error %d
- The driver was unable to install the device interrupt handler. This should
- wpi%d: %s: bus_dmamap_load failed, error %d
- The driver was unable to map newly allocated mbuf to device visible
address space. Contents of currently received frame will be lost. This
should not happen.

Hostap mode is not directly supported by the device; it is implemented through
IBSS mode (as a result, DFS/passive channels are not available in this mode).
Powersave may be unstable on some networks (results in occasional 'wpi%d: device
timeout' messages); you can try to disable it to improve device
