Wireless connection failing

Question

Archlinux fresh installation.
Laptop: HP Compaq 6720s with Broadcom 4312 wireless adapter with proprietary driver:
$ lspci -vnn -d 14e4
lspci: -d: ':' expected
[archio@laportabile ~]$ lspci -vnn -d 14e4:
10:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
Subsystem: Hewlett-Packard Company BCM4312 802.11b/g Wireless LAN Controller [103c:137d]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at e4000000 (64-bit, non-prefetchable) [size=16K]

Kernel driver in use: wl
$ lsmod | grep -i wl
wl 2557001 0
lib80211 3949 2 wl,lib80211_crypt_tkip
cfg80211 433688 1 wl
Wired connection works fine.
I've a WPA2 wireless connection at home which I can't connect to.
Both wicd and network manager GUI fails on authentication.
Wireless networking has always worked fine in the past using "wl" driver.
I've tried:

Where are you putting in your WPA passphrase? Do you have wpa_supplicant running?  I think you need it to associate with an encrypted network.  Have you tried using wifi-menu from netcfg[1]? Alternatively, you could use netctl[2] from [testing] because it's going to take over for netcfg once it hits the stable repos.
[1]https://www.archlinux.org/packages/core/any/netcfg/
[2]https://www.archlinux.org/packages/testing/any/netctl/
1) Put it in NetworkManager and wicd applet (obviously I don't use both at the same time)
2) How do I see if wpa_supplicant is running?
I've tried to connect manually to a non protected wifi but it's not doing anything:

I have the same card you have on my Inspiron1525 and sometimes wpa_supplicant/netcfg give me some headaches, I don't know why.
My personal recommendation is that you use NetworManager and nm-applet along with the b43 driver, as PinkPanther  noted.
EDIT1: Also check that b43 and wl modules are not loaded at the same time, b43 module might be loaded automatically.

b43 NEVER worked good to me, since I was Using Ubuntu 5 years ago. (this computer has seen Ubuntu, debian, openSUSE, debian, arch and none of them worked good with b43).
I'll try them again.
EDIT: Ok b43 installed and loaded by lsmod and still not working, it doesn't event try to connect, it flash for a millisecond and nothing more.
Do i have to extract b43 firmware with b43-fwcutter as explained here? http://linuxwireless.org/en/users/Drive … ed_devices
archwiki doesn't mention doing anything like it.
Does installing b43-fwcutter execute it?
EDIT 2: b43 up and running, but still can't connect. I've tried wpa_supplicant also.
$ sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
