Can not connect to a wireless network

I recently installed xfce4 with a wired connection and used the newly updated install cd ISO. After using the wired connection to install what I needed I went on to install what is needed for the wireless setup. I went with wpa_supplicant and networkmanager. I configured my wpa_supplicant.conf appropriately and installed the drivers needed for my atheros wireless adapter.

02:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

I was able to scan for networks and I can see my LED light come on indicating my adapter is working. However.. when I tried to "dhcpcd wlan0" the connection or lack thereof timed out.

Also I get this error from rfkill:

    # rfkill list all
    0: acer-wireless: Wireless LAN
            Soft blocked: yes
            Hard blocked: no
    1: phy0: Wireless LAN
            Soft blocked: no
            Hard blocked: yes

what could be causing this problem? I haven't found any info that is helpful so far.

rfkill could be blocking your wifi-adapter. 

$ rfkill unblock 0 
$ rfkill list

What laptop model are you using?  I had trouble getting my Acer laptop connected via wifi when I first put Arch on it too. 

Check this page too.

Are you using wicd-gtk or nm-applet for network management?

What is the output of the following commands?

$ ip addr 
$ iwconfig 
$ ping 127.0.0.1 -c 4 -w 3
# dhcpcd wlan0

Install net-tools

$ sudo pacman -S net-tools

and run

$ ifconfig -a

and copy and paste the ouput into your reply please.
