5# Preamble
6
7This document is written by a DragonFlyBSD newbie for other newbies, so there may be a better way to setup the ipw2200 wlan adapter. It was tested on a Asus V6800 notebook, but hopefully it should apply to all notebooks with ipw2200 adapters. WPA encryption is not available now (April 2006), and I wasn't unable to get my wlan adapter to establish a WEP connection, so I have only an unprotected WIFI connection, but that may be a problem with my notebook or my router.

11# Prerequisites
12
13You need two things to setup your ipw2200 adapter:
14
15
16* the if_iwi kernel modules for DragonFlyBSD
17
18* the firmware for your ipw2200 wlan adapter
19
20
21
22# Loading the if_iwi kernel module
23
24If you've done a fresh install of DragonFlyBSD, the kernel module should already be "ready to use". This is how you can load it:
25
26 # kldload if_iwi
27
28 If you don't get an error message, the necessary module is loaded now. If you get this message:
29
30 kldload: can't load if_iwi: File exists
31
32 this is ok, too. It means, that the module has already been loaded for you. BTW: you can check, if it's already loaded with this command:
33
34 # kldstat | grep if_iwi
35
36 This should return something similar to this, if the module is loaded:
37
38 6 1 0xc0759000 c2c8 if_iwi.ko
39
40 If you don't have the kernel module available, you must build a new kernel. You can find the necessary information to do that in the ["DragonFlyBSD Handbook, chapter 9"](http://leaf.dragonflybsd.org/~justin/handbook/kernelconfig.htm) : (http://leaf.dragonflybsd.org/~justin/handbook/kernelconfig.html) .
41
42 Later, you can automate loading of the kernel driver by using the /boot/loader.conf file.
43
44 # Getting the firmware
45
46 If you've already set up the pkgsrc system on your machine, you can install it by
47
48
49 # cd /usr/pkgsrc/sysutils/iwi-firmware
50 # make install clean
51
52
53and continue reading at the next section ("Loading the firmware").
54
55Otherwise, you can ["download it from" ](http://damien.bergamini.free.fr/iwifw/ipw2200-fw-2.3.tgz) (http://damien.bergamini.free.fr/iwifw/ipw2200-fw-2.3.tgz) and extract to a new directory, e. g. /usr/libdata/iwi_firmware:
56
57
58 # mkdir /tmp/firmware
59 # cd /tmp/firmware
60 # fetch http://damien.bergamini.free.fr/iwifw/ipw2200-fw-2.3.tgz
61 # tar xvfz ipw2200-fw-2.3.tgz
62 # mkdir /usr/libdata/if_iwi
63 # mv *fw /usr/libdata/if_iwi
64 # cd ..
65 # rm -fd firmware
66
67
68Unfortunately, you must rename the files:
69
70
71 # cd /usr/libdata/if_iwi
72 # mv ipw-2.3-ibss_ucode.fw iwi-ucode-ibss.fw
73 # mv ipw-2.3-sniffer.fw iwi-sniffer.fw
74 # mv ipw-2.3-boot.fw iwi-boot.fw
75 # mv ipw-2.3-bss.fw iwi-bss.fw
76 # mv ipw-2.3-sniffer_ucode.fw iwi-ucode-sniffer.fw
77 # mv ipw-2.3-bss_ucode.fw iwi-ucode-bss.fw
78 # mv ipw-2.3-ibss.fw iwi-ibss.fw
79
80
81# Loading the firmware
82
83Now, you can load the firmware:
84
85
86 # iwicontrol iwi0 -d /usr/libdata/if_iwi
87
88
89
90# Configuring the WLAN interface
91
92Now, you can configure your ipw2200 adapter.
93
94First example: without WPA and WEP
95
96
97 # ifconfig iwi0 inet <ip-address> netmask <netmask> ssid <myssid> wepmode off
98
99Second example: with WEP
100
101
102 # ifconfig iwi0 inet <ip-address> netmask <netmask> ssid <myssid> wepmode on wepkey <mywepkey>
103
104
105(example for a 104/128 bit wepkey hex value: 0xf6fa1c61abc3ca5a3787fdaeae)
106
107Check your success (example):
108
109
110 # ifconfig iwi0
111 iwi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
112 inet 192.168.2.101 netmask 0xffffff00 broadcast 192.168.2.255
113 inet6 fe80::212:f0ff:fe07:f5c8%iwi0 prefixlen 64 scopeid 0x3
114 ether 00:12:f0:07:f5:c8
115 media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)
116 status: associated
117 ssid catalan 1:catalan
118 channel 6 authmode OPEN powersavemode OFF powersavesleep 100
119 rtsthreshold 2312 protmode CTS txpower 100
120 wepmode OFF weptxkey 1
121
122
123We have the IP-address 192.168.2.101 with netmask 255.255.255.0 (0xffffff00), and are connected ("associated") to an access point with the name "catalan". We don't use WEP (wepmode OFF) here.
124
125
126As said at the beginning, I wasn't able to connect to my router/AP with WEP enabled, but it should work (tm). I was only able to make a connection with enabled SSID broadcast, but may be you'll have more luck ;-)
