[SOLVED AGAIN] Wireless Driver for Broadcom BCM4312 (14e4:4315)?

Question

Hello,
I've recently switched to Arch after having Ubuntu installed on my laptop for a year. I'm also been an on/off Debian (and Debian-based) user on my main Desktop for the past two years or so. So it comes to no surprise that it's taking me a lot to get used to a brand-new packaging system, much less having to essentially build it from the ground up. But I'm always up for the challenge.
I switched from Ubuntu (Kubuntu, specifically) because of the problems it's recently been having in regard to speed and performance. Not to mention the constant freezing every hour. My Arch install when along smoothly. I've been running off of a wired connection, but I really need to get my wireless set up. This is my first roadblock.
In Ubuntu, it was a 'just-worked' kinda think hen it came to my wireless. The only problem that I've ever had with it during the Ubuntu times was when I first installed Ubuntu: they had not yet added in the Broadcom drivers (or, at least, not a compatible one). And so I had to do a bit of research to get it to work. Since then, I've lost track of the Linux development on my particular card.
But now it doesn't work, and I can't find a way to get it to work. I've looked at various wiki's and forum posts, but I can't seem to find one that's up-to-date.
Any help?

Answer 1

Today's the first day I've been able to actually test the installation to see if it actually worked. Sadly, it doesn't seem to have. I've followed the instructiong on the Broadcom 4312 wiki page, and then moved on to the wireless wiki page to set it up.
Running iwconfig, I can see that the driver enable wireless:
$ iwconfig
lo no wireless extensions.
eth0 IEEE 802.11 Nickname:""
Access Point: Not-Associated
Link Quality:5 Signal level:0 Noise level:0
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
eth1 no wireless extensions.
However, running iwlist scan gives an error:
$ iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
eth1 Interface doesn't support scanning.
The wiki says that this is likely to be because I haven't installed the firmware? I've added the wl module to /etc/rc.conf, but I haven't changed any other configuration options. For example, I haven't really touched the networking section of the file, except to change eth0 to eth1 (installed the wireless driver switched the interface). Do I need to add eth0 (wireless) to this section? Or do I have to configure network profiles? I'm really new to all these new configuration options, so I don't really know  where to start.
Here the networking setion of /etc/rc.conf:
# NETWORKING
# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts
HOSTNAME="ryan-laptop"
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
eth1="dhcp"
INTERFACES=(eth1)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network.d
# This now requires the netcfg package
#NETWORKS=(main)
I haven't touched any other files...
I'll continue looking through the wiki.
Also, I haven't tried KDE4's network manager to see if it has problems yet. I was hoping to take the installation one step at a time and get everything working the way I want it to on the console side before moving to and tweaking the graphical side.
