Allright, I hate having to post for help but I've been troubleshooting this for hours. Ifconfig will not bring up the wlan0 interface but it shows in iwconfig and ifconfig -a. See outputs below.
lspci:

I've done the install with the firmware from Here
Asterisks in iwconfig are replacing real ssid and wep key for this forum post.
I'm running out of ideas... Thanks in advance.

thrashpirate,
What driver are you using ?
The testing vanilla-sources has bc43 included and its reported to work well - I don't have on to test.

I started with genkernel but have since recompiled and disabled some unneeded things. I'm not 100% sure as I've always used ndiswrapper but after this new install... in dmesg it was giving an error about microcode (I don't recall exact error but it gave a link for firmware)... that's when I followed the link (b43legacy, b43-fwcutter).
here's my lsmod output:

thrashpirate,
What kernel are you using ?
uname -a will show you.
What drivers did you emerge ?
You need to get rid of the firmware error or it cannot work regardless of any of the above.
What *exactly* did the error say ?

Hey, thanks for the reply. The error is gone after I followed the link the error gave to download the b43legacy firmware. Are there additional drivers I need to use?
Kernel:
| Code: | thrashpirate ~ # uname -a
Linux thrashpirate 2.6.23-gentoo-r3 #2 Fri Dec 28 17:35:36 EST 2007 i686 mobile AMD Athlon(tm) XP-M 2400+ AuthenticAMD GNU/Linux |
Here is what dmesg shows now after downloading the b43legacy firmware and b43-fwcutter(no longer an error).
dmesg:
| Code: | bcm43xx: Chip ID 0x4306, rev 0x3
bcm43xx: Number of cores: 5
bcm43xx: Core 0: ID 0x800, rev 0x4, vendor 0x4243
bcm43xx: Core 1: ID 0x812, rev 0x5, vendor 0x4243
bcm43xx: Core 2: ID 0x80d, rev 0x2, vendor 0x4243
bcm43xx: Core 3: ID 0x807, rev 0x2, vendor 0x4243
bcm43xx: Core 4: ID 0x804, rev 0x9, vendor 0x4243
bcm43xx: PHY connected
bcm43xx: Detected PHY: Analog: 2, Type 2, Revision 2
bcm43xx: Detected Radio: ID: 2205017f (Manuf: 17f Ver: 2050 Rev: 2)
bcm43xx: Radio turned off
bcm43xx: Radio turned off

Since the error is gone, I assume it can now deal with the wireless card. Now what I don't understand is why wlan0 shows up in ifconfig -a but when I try to bring it up, I get:
| Code: | thrashpirate ~ # ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory
|
Thanks again. |

I just noticed one other thing in regards to wireless in dmesg:
| Code: | ieee80211: 802.11 data/management/control stack, git-1.1.13
ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com>
ieee80211_crypt: registered algorithm 'NULL'
ieee80211_crypt: registered algorithm 'WEP' |
Any ideas? |

thrashpirate,

Yes, thanks for the tip. I didn't check after I tried but also checking syslog the error is there:
/var/log/messages.
error:
| Code: | bcm43xx: PHY connected
bcm43xx: Error: Microcode "bcm43xx_microcode5.fw" not available or load failed.
bcm43xx: core_up for active 802.11 core failed (-2)

thrashpirate,
The device needs the file bcm43xx_microcode5.fw to be installed in /lib/firmware.
Thats were the kernel looks for the firmware when the module loads.
If the file is missimg, or called something else, it will not be found. A compressed file will not work either.

Thanks! that worked to get it to come up in ifconfig.
Now I'm trying to get it to recognize my wireless network.
| Code: | thrashpirate ~ # iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
wlan0 No scan results |
The reason I never got the bcm43xx_microcode5.fw into /lib/firmware was because the site says if you have the 4306 Broadcom model you should use the b43legacy firmware with b43-fwcutter. But since it needed bcm43xx_microcode5.fw I had to use the b43 firmware with bcm43xx-fwcutter to get it to work.
Now that the int comes up with ifconfig hopefully I can get it to recognize my network.
One other thing that I'm not sure is important... the light on the wireless card (laptop) is not on.
dmesg output:
| Code: | bcm43xx: PHY connected
bcm43xx: Microcode rev 0x127, pl 0xe (2005-04-18 02:36:27)
bcm43xx: Radio turned on
bcm43xx: Radio disabled by hardware
bcm43xx: Chip initialized
bcm43xx: 30-bit DMA initialized
bcm43xx: Keys cleared
bcm43xx: Selected 802.11 core (phytype 2)
bcm43xx: set security called, .active_key = 0, .level = 1, .enabled = 1, .encrypt = 1
|
closer and closer
Any reason I wouldn't get any results from a scan? I know the signal strength is good because the windoze box next to this laptop gets a signal strength around 70% |

thrashpirate,
A few things. The firmware you require is determined by the kernel module you build. The filename is hard coded into it.
If you have chosen the wrong kernel module, it will ask for the firmware it wants, not the firmware your device actually needs.
Many wireless interfaces need to be up before they will admit to being wireless. fixes that.
Now you can drive the wireless extensions with ifwconfig. See
iwspy is also useful.
| Code: | | bcm43xx: Radio disabled by hardware |
suggests that your system has a Radio on/off button too.

I finally got iwlist scan to show my network but upon a reboot I'm back at
| Code: | iwlist scan
No scan results |
The driver appears to be working and the radio is now enabled ... any reason after a reboot I would get No scan results?
ifconfig will let me bring up the interface and it shows in iwconfig
The driver is loaded 
Thanks! |

Some additional information... I configured /etc/conf.d/net
| Code: | essid_eth1="wireless"
config_eth1=( "dhcp" )
dhcpd_eth1="-t 15"
|
Note that my wireless interface is no longer wlan0, not a big deal but too long to explain.
When I try to start the interface I receive:
| Code: | thrashpirate init.d # /etc/init.d/net.eth1 start
* Starting eth1
* Configuring wireless network for eth1
* Failed to configure wireless for eth1 [ !! ]
|
I tailed /var/log/messages and saw:

thrashpirate,
You may need some extra commands in /etc/conf.d/net
It may need some pauses after scanninig and so on.
Some examples are given in /etc/conf.d/net.example, others in The Hanbook
