Wireless not working with Live ISO 2014.04i

I am trying to run the Live version of Netrunner 2014.04i.
Everything seems to be ok, except the wireless connection.
The connection is correctly displayed the NetworkManager, but when I enter the passphrase and click on “Connect” nothing happens.

Here is some useful information:

$ lspci | grep -i wireless
03:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

$ lsmod | grep wl

cfg80211              327507  1 wl

$ iwconfig

I guess you are missing the
broadcom-wl driver for your card.
Please install the package linux310-broadcom-wl to get it working.

linux310-broadcom-wl is already installed:

$ sudo pacman -Ss linux310-broadcom-wl 
extra/linux310-broadcom-wl (linux310-extramodules) [installed]
    Broadcom 802.11 Linux STA wireless driver BCM43142.

You might find a sulution in the users notes section here:

Could be this new NM thing frontend has some weird behaviour… I remember to have happened to me but then after next login, all seemed fine… Will need to test this again with live version to be sure.
