PRO/Wireless 2100 IEEE 802.11b wireless network device
ipw* at pci?
driver provides support for the Intel
PRO/Wireless 2100 Mini PCI network adapter.
These are the modes the ipw
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.
- IBSS mode
- Also known as IEEE ad-hoc mode
or 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
- 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.
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
driver relies on the software 802.11 stack
for both encryption and decryption of data frames.
driver can be configured at runtime with
The driver needs at least version 1.3 of the following firmware files, which are
loaded when an interface is brought up:
These firmware files are not free because Intel refuses to grant distribution
rights without contractual obligations. As a result, even though
includes the driver, the firmware files cannot
be included and users have to find these files on their own. The official

A prepackaged version of the firmware can be installed using
The following example scans for available networks:
# ifconfig ipw0 scan
example configures ipw0 to join network “mynwid”, using WPA key
“mywpakey”, obtaining an IP address using DHCP:
- ipw0: device timeout
- The driver will reset the hardware. This should not
- ipw0: error N, could not read firmware
- For some reason, the driver was unable to read the
firmware image from the filesystem. The file might be missing or
