[Solved]Issues connecting to wireless with Broadcom BC4312

This is my xth installation of Arch Linux and I'm having some issues connecting to wireless as I usually do. Normally I am able to resolve this.
Currently, when trying to connect with netcfg it is giving me the error "WPA Authentication / Association Failed". My network does not use any authentication.
I am using netcfg version 2.6.8-1. My laptop is a Dell Inspiron 1545.

I fixed the switched module names that comes along with broadcom-wl. I have blacklisted the b43, ssb and brcm80211 modules.

Here is the output of netcfg:

DEBUG: Loading profile home
DEBUG: Configuring interface wlan0
DEBUG: wireless_up stop_wpa wlan0
DEBUG: wireless_up start_wpa wlan0 /run/network//wpa.wlan0/wpa.conf wext
DEBUG: wireless_up stop_wpa wlan0
DEBUG: wireless_up Configuration generated at /run/network//wpa.wlan0/wpa.conf
DEBUG: wireless_up ifup
DEBUG: wireless_up start_wpa wlan0 /run/network//wpa.wlan0/wpa.conf wext
DEBUG: wireless_up wpa_check
DEBUG: wpa_cli -p /run/wpa_supplicant -i wlan0 status
> WPA Authentication / Association Failed
DEBUG: profile_up connect failed

The contents of that specified file are:

ctrl_interface=/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="olivegarden"
key_mgmt=NONE
}

I have never touched that particular file.

Here is my profile, located in /etc/network.d/home:

CONNECTION='wireless'
DESCRIPTION='A simple opened wireless connection'
INTERFACE='wlan0'
SECURITY='none'
ESSID='olivegarden'
IP='dhcp'
# Uncomment this if your ssid is hidden
#HIDDEN=yes
WPA_DRIVER='wext'

And the results of an iwconfig:

          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated

          Power Managementmode:All packets received
          Link Quality=5/5  Signal level=0 dBm  Noise level=0 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

On a side note, I am not able to dhcpcd. It broadcasts for a lease and then times out.
An iwlist scan gives me the message "Failed to read scan data : Invalid argument." I am unsure if these are related.

I have been doing this for several hours now and am not quite sure what the issue is. Googling has not provided much assistance either. Any help is appreciated.

Try the b43 driver instead of wl.

Re: [Solved]Issues connecting to wireless with Broadcom BC4312

That's giving me even more issues. It's telling me "Could not set interface wlan0 flags: Operation not possible due to RF-kill
Failed to initialize driver interface
> wpa_supplicant did not start, possible configuration error"

Re: [Solved]Issues connecting to wireless with Broadcom BC4312

Ok, check with "rfkill list" how the radio is killed. If it's a soft block, "rfkill unblock [device]" should do it. If it's a hard block, your laptop must have a hardware switch that needs to be, well, switched.

Well...I feel pretty stupid now. That'll do it...
Thanks. I wish this had an indicator light or something.
