WLAN Problems :( [Broadcom 4312 + b43]

Hey there.

Today I freshly installed Arch Linux to my Notebook and I wanted to get the WLAN working.
Because I have an Broadcom 4312 Wireless Card, I thought of using the b43 driver, for injection etc

I got me the b43-fwcutter 012, whcich is the newest version.
I first tried the oldest version of the wl drivers (something with 80), but it didn't work, when I read, that for 4312 you have to take the new 178 driver (As you can read here : http://linuxwireless.org/en/users/Drive … stallation ).
I downloaded it, but for some reason the fwcutter said it has a wrong md5 (WTF?!). The I tried the driver from 2008 [150] but I still doesnt work.

Now my Notebook isn't even starting at the moment, so I cant dump any logs, but I can describe you what's in them:

ifconfig -a

Only my network card and lo

lsmod

b43
mac80211
_no_ wl

lspci | grep -i net

My Network Card
The Broadcom Card 4312

grep MODULES /etc/rc.conf

MODULES=(b43)

dmesg | grep -i broadcom

b43-phy0: Broadcom 4312 WLAN found
Broadcom 43xx driver loaded [ Features: PMLR, Firmware-ID: FW13 ]

I hope you guys can help me, because else I have to give up and go back to Ubuntu or, even worse, to Windows (ok, thats a joke:P)

So far,

kingfinn

You should be using the wl driver only, so blacklist b43.

Search the wiki for Broadcom 4312, there's a page dedicated to it.

Found it, but it describes the wl driver and I want to use the b43...
It says that the b43 isnt supported but thats actually wrong.

//Edit. I saw that I have a different Chip which isnt actually supported...

14e4:4312 supported (802.11g only) BCM4312 802.11a/b/g
   

14e4:4312 not supported - ID is duplicated BCM4312 802.11b/g

I have the one without a standart... screw it.

Thanx for your help!

Hey sorry for dubblepost, but I am connected to my WLAN now.
I got another question:
How do I get internet to work now?
I want to install something via pacman, so what do I need to configure now?

Edit: Just had to start dhcpcd and update db.

PROBLEMS SOLVED

If you want to use b43 as a module try kernel 2.6.32
Initial LP-PHY support for BCM 4312 is there and might work.
