I have a Gateway 6454 laptop with 2.6.21-gentoo-r3 amd64 kernel running.
I am trying to set up the wireless network. I have never done this
before so I started with the Handbook's Wireless Networking section. I
begin by attempting to figure out what network card I have. lspci
reports the wireless network chip as:
05:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan
mini-PCI (rev 01)
Thus it seems the bcm43xx driver is what I need. I selected it to
compile as a module with DMA+PIO transfer mode selected. Along with it,
I compiled:
<M> Generic IEEE 802.11 Networking Stack
--- IEEE 802.11 WEP encryption (802.1x)
<M> IEEE 802.11i CCMP support
<M> IEEE 802.11i TKIP encryption
<M> Software MAC add-on to the IEEE 802.11 networking stack
I wasn't sure exactly what I needed so I compiled all as modules and
loaded all. My though was that once I had it working, I would remove
modules to see what I really needed.
Googling revealed something about cutting firmware. Thus I emerged
bcm43xx-fwcutter and followed some tidbits I found on the web about how
that worked. First I grabbed the latest Windows driver and copied
bcmwl564.sys (since I am using an amd64 kernel). When running
bcm43xx-fwcutter -i bcmwl564.sys, I got the following error/output:
*** WARNING ***
This file contains new version4
firmware. v4 firmware is _not_ supported by
the driver in mainline kernels. For v4 firmware
you need latest bcm43xx development version
(wireless-dev kernel tree). If you don't know what
this warning is about, use a 3.xx.xx.xx driver version
instead to extract the firmware.
Well I couldn't find a version 3 driver and I have no idea how to use
the "wireless-dev kernel tree" even after Googling for another hour.
However I did find a Linux driver for the BCM43xx named "wl_apsta.o" but
I really don't know much about it. Thus I extracted firmware from that
and copied it to /libs/firmware. An 'ifconfig eth1 up' and now I was
able to get the wireless card recognized:

Anyway, next I continued following the Gentoo Handbook on Wireless
Networking
(http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4),
specifically the WPA Supplicant section. Here's the contents of the
files I created pursuant to that page:
tagalong ~ # cat /etc/conf.d/net
# From http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4
# Prefer wpa_supplicant over wireless-tools
modules=( "wpa_supplicant" )
# It's important that we tell wpa_supplicant which driver we should
# be using as it's not very good at guessing yet
wpa_supplicant_eth1="-Dwext"
tagalong ~ # cat /etc/wpa_supplicant/wpa_supplicant.conf
# The below line not be changed otherwise we refuse to work
ctrl_interface=/var/run/wpa_supplicant
# Ensure that only root can read the WPA configuration
ctrl_interface_group=0
# Let wpa_supplicant take care of scanning and AP selection
ap_scan=1
# This is a network block that connects to any unsecured access point.
# We give it a low priority so any defined blocks are preferred.
network={
key_mgmt=NONE
priority=-9999999
}
network={
ssid="DrewNet"
key_mgmt=NONE
key_mgmt=NONE
wep_key0="ffffffffff" # not the real keys - but then it's WEP so
wep_key1="ffffffffff" # am I hiding them? :)
wep_key2="ffffffffff"
wep_key3="ffffffffff"
wep_tx_keyidx=0
priority=5
}
Now when I fire up wpa_supplicant, it seems to associate:
wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -ieth1 -d

OK, so good. Now I issue a DHCP request as so:
tagalong ~ # dhcpcd -dd eth1
Info, eth1: dhcpcd 3.0.17 starting
Info, eth1: hardware address = 00:14:a5:fc:3b:b2
Info, eth1: broadcasting for a lease
Debug, eth1: sending DHCP_DISCOVER with xid 0x500d3c30
Debug, eth1: waiting on select for 20 seconds
Debug, eth1: sending DHCP_DISCOVER with xid 0x500d3c30

Debug, eth1: sending DHCP_DISCOVER with xid 0x500d3c30
Error, eth1: timed out
Info, eth1: exiting
I ran tcpdump on eth1 and no packets are leaving the interface. Thus I
assume that's why I'm not getting an address. The DHCP server has no
problems with other machines on my network. The Wireless access point
works with other devices too. So I'm stumped. Is this related to
firmware? Other ideas?
I appreciate you reading this far and will gladly accept any suggestions.
Thanks,
Drew
