6 +**** HOWTO get bcm43xx-dscape running ****
7 +**** ****
8 +
9 +This is a port of the bcm43xx driver for the devicescape ieee802.11
10 +stack. The devicescape ieee802.11 stack is an advanced out-of-mainline
11 +802.11 protocol module.
12 +I will call the "devicescape ieee802.11 stack" simply "dscape" in the
13 +following text.
14 +
15 +
16 +*** Setting up the bcm43xx driver with dscape is currently non-trivial,
17 +*** as several modifications to the kernel and the userland
18 +*** wpa_supplicant tool are required. We are working on it...
19 +
20 +
21 +1) You need to patch the kernel with the ieee80211-devicescape stack
22 + and the bcm43xx-dscape port.
23 + Both are available in one cummulative at:
24 + ftp://ftp.bu3sch.de/bcm43xx-snapshots/all-in-one/bcm43xx-dscape/
25 + Read the instructions on http://bcm43xx.berlios.de/ for how to apply
26 + this patch.
27 +
28 + Patch the kernel, compile and install it.
29 + When configuring, enable
30 + "Networking/Generic IEEE 802.11 Networking Stack (dscape)"
31 + and
32 + "Device Drivers/Network device support/Wireless LAN (non-hamradio)/Broadcom BCM43xx wireless support (DeviceScape stack)"
33 + Reboot.
34 +
35 +2) Set up a wpa_supplicant config file in /etc/wpa_supplicant.conf
36 + Here is an example for an AES WPA encrypted network:
37 +
38 + # WPA AES encryption
39 + ctrl_interface=/var/run/wpa_supplicant
40 + network={
41 + ssid="ACCESSPOINT_SSID"
42 + key_mgmt=WPA-PSK
43 + proto=WPA
44 + pairwise=CCMP TKIP
45 + group=CCMP TKIP
46 + psk="MY PASSPHRASE"
47 + priority=3
48 + }
49 +
50 +3) Take a bottle of your favourite beer, open it and take a swallow.
51 +
52 +4) Now it's time to bring the driver up.
53 + Do modprobe bcm43xx-d80211 to load the driver.
54 + There is an ugly bash script to bring the driver up after insmod.
55 + It is found in the "scripts" subdirectory of the patched kernel
56 + tree and is called "bcm43xx-d80211-sta_up.sh".
57 + Call scripts/bcm43xx-d80211-sta_up.sh --help to get some usage information.
58 + It may suffice to call scripts/bcm43xx-d80211-sta_up.sh without any parameters. See
59 + the help. Default parameters, which are used when called without parameters,
60 + are explained there.
61 +
62 +5) If you want to access the internet, make sure your default route
63 + is correctly set up with your gateway's IP:
64 + route add default gw 192.168.xxx.xxx
65 +
66 +6) Take another swallow from your bottle of beer and test if it works:
67 + ping www.kernel.org
68 +
69 +7) If it works, drink the rest of your beer. Otherwise read this HOWTO again,
70 + and again and again. Complain to bcm43xx-dev@lists.berlios.de, if it still
71 + does not work.

77 + BCM43xx Linux Driver Project
78 + ============================
79 +
80 +About this software
81 +-------------------
82 +
83 +The goal of this project is to develop a linux driver for Broadcom
84 +BCM43xx chips, based on the specification at
85 +http://bcm-specs.sipsolutions.net/
86 +
87 +The project page is http://bcm43xx.berlios.de/
88 +
89 +This is a port of the bcm43xx driver for the devicescape ieee802.11
90 +stack.
91 +
92 +Requirements
93 +------------
94 +
95 +1) Linux Kernel 2.6.16 or later
96 + http://www.kernel.org/
97 +
98 + See Documentation/networking/bcm43xx-d80211-HOWTO.txt for further
99 + instructions.
100 +
101 +2) Firmware Files
102 +
103 + Please try bcm43xx-fwcutter. It can extract the firmware from various
104 + binary driver files and supports driver files from Windows, MacOS and
105 + Linux. You can get bcm43xx-fwcutter from http://bcm43xx.berlios.de/.
106 + Also, bcm43xx-fwcutter comes with a README file for further instructions.
