Broadcom BCM4312 wireless under Arch setup

I have a Dell Latitude laptop with a Broadcom BCM4312 wireless and I need to use it under the installation. I have only access to wireless, no wired connection.

I have read the wiki page, searched at the forum, used google but nothing seems to work.
Can I get my wireless card to work without having access to internet?

When I run

iwconfig

it seems to detect my wireless but the

ifconfig wlan0 up

wont work.

I hope you guys can understand me and help me with my problem. Can it be that the driver is not included on the CD/Kernel?

EDIT I can install with the core-image, but in which case I will need the wireless to work.

EDIT 2 I forgot this.
When I installed the system I selected the b43-fwcutter and the wireless_tools (or something like that) from the package selection

Have you ried the wiki? You can download the needed packages and put them on an USB stick. http://wiki.archlinux.org/index.php/Broadcom_BCM4312

Have you assigned an IP to your wireless card? Or started dhcp?

I have that card and I use broadcom-wl from aur. You will need header packages and such, way easier with a cable till you build the module. Just follow the wiki.

What do you mean it doesn't work?  Is there an error message?  Or, does if work, but internet doesn't work?  If so, then maybe you don't have an IP address.  Did you run dhcpcd or something like that?

Driver included with kernel is B43, which does not work so well (at lesast for me). You should download the broadcom-sta source, check if you installed the kernel26-headers, if not, will have to instal them by  hand. Then modify the source, so it would compile on a 2.6.34 kernel and then compile it and folow the guide on readme file in the broadcom-sta source.
Broadcom-sta source: http://www.broadcom.com/support/802.11/linux_sta.php
In the broadcom-sta in the file "linuxver.h" you should change the  line 23 from

"#include <linux/autoconf.h>"
to
"#include <generated/autoconf.h>"

after you have compiled the driver copy it (read the readme in the tarball) and  in your rc.conf in modules section blacklist the ssb and b43    and add wl "modules=( !ssb !b43 wl)"
