Since you had posted that in the same thread, I had presumed that
you had accounted for that... :-)

As you wish...you know I love to shake-up the history in my trees... :-(

-**** ****
-**** HOWTO get bcm43xx-dscape running ****
-**** ****
-
-This is a port of the bcm43xx driver for the devicescape ieee802.11
-stack. The devicescape ieee802.11 stack is an advanced out-of-mainline
-802.11 protocol module.
-I will call the "devicescape ieee802.11 stack" simply "dscape" in the
-following text.
-
-
-*** Setting up the bcm43xx driver with dscape is currently non-trivial,
-*** as several modifications to the kernel and the userland
-*** wpa_supplicant tool are required. We are working on it...
-
-
-1) You need to patch the kernel with the ieee80211-devicescape stack
- and the bcm43xx-dscape port.
- Both are available in one cummulative at:
- ftp://ftp.bu3sch.de/bcm43xx-snapshots/all-in-one/bcm43xx-dscape/
- Read the instructions on http://bcm43xx.berlios.de/ for how to apply
- this patch.
-
- Patch the kernel, compile and install it.
- When configuring, enable
- "Networking/Generic IEEE 802.11 Networking Stack (dscape)"
- and
- "Device Drivers/Network device support/Wireless LAN
(non-hamradio)/Broadcom BCM43xx wireless support (DeviceScape stack)"
- Reboot.
-
-2) Set up a wpa_supplicant config file in /etc/wpa_supplicant.conf
- Here is an example for an AES WPA encrypted network:
-
- # WPA AES encryption
- ctrl_interface=/var/run/wpa_supplicant
- network={
- ssid="ACCESSPOINT_SSID"
- key_mgmt=WPA-PSK
- proto=WPA
- pairwise=CCMP TKIP
- group=CCMP TKIP
- psk="MY PASSPHRASE"
- priority=3
- }
-
-3) Take a bottle of your favourite beer, open it and take a swallow.
-
-4) Now it's time to bring the driver up.
- Do modprobe bcm43xx-d80211 to load the driver.
- There is an ugly bash script to bring the driver up after insmod.
- It is found in the "scripts" subdirectory of the patched kernel
- tree and is called "bcm43xx-d80211-sta_up.sh".
- Call scripts/bcm43xx-d80211-sta_up.sh --help to get some usage information.
- It may suffice to call scripts/bcm43xx-d80211-sta_up.sh without any
parameters. See
- the help. Default parameters, which are used when called without
parameters,
- are explained there.
-
-5) If you want to access the internet, make sure your default route
- is correctly set up with your gateway's IP:
- route add default gw 192.168.xxx.xxx
-
-6) Take another swallow from your bottle of beer and test if it works:
- ping www.kernel.org
-
-7) If it works, drink the rest of your beer. Otherwise read this HOWTO again,
- and again and again. Complain to bcm43xx-dev@lists.berlios.de, if it still
- does not work.

- BCM43xx Linux Driver Project
- ============================
-
-About this software
--------------------
-
-The goal of this project is to develop a linux driver for Broadcom
-BCM43xx chips, based on the specification at
-http://bcm-specs.sipsolutions.net/
-
-The project page is http://bcm43xx.berlios.de/
-
-This is a port of the bcm43xx driver for the devicescape ieee802.11
-stack.
-
-Requirements
-------------
-
-1) Linux Kernel 2.6.16 or later
- http://www.kernel.org/
-
- See Documentation/networking/bcm43xx-d80211-HOWTO.txt for further
- instructions.
-
-2) Firmware Files
-
- Please try bcm43xx-fwcutter. It can extract the firmware from various
- binary driver files and supports driver files from Windows, MacOS and
- Linux. You can get bcm43xx-fwcutter from http://bcm43xx.berlios.de/.
- Also, bcm43xx-fwcutter comes with a README file for further
instructions.
