Can't connect to my WPA AP using wpa_supplicant

Question

Hi!
I've got a problem. I've been playing around with Archlinux trying to set up a small server using my laptop. Everything's been working fine and I've been able to get past any problems I've come across using the wonderful wiki. However, my wireless internet connection all of a sudden stopped working today. I've been messing some config files and I think I might have changed something I shouldn't. So I tried to start at square one again following the steps described in the wpa_supplicant wikipost. However, something's not working. After issuing the following command:
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
I still can't get an IP using dcphcd wlan0, it just says "timed out". Output:
[ola@stashbox wpa_supplicant]$ sudo wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf -d

I'd be thankful if anyone could take the time to give me a few ideas as to how to proceed.

The process that i use every time that i want to get connected using wpa_supplicant:
# ifconfig eth0 down && ifconfig wlan0 up
    You have to shutdown eth0 connection to avoid conflicts
# wpa_passphrase ESSID "PASSWORD" > /etc/wpa_supplicant.conf
    Where ESSID is your wireless network name, and PASSWORD your router password
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
    -B to run as daemon, -D driver parameter using "wext" driver.-i interface "wlan0", -c specify configuration file /etc/wpa_supplicant.conf
    For dhcp:
# dhcpcd wlan0
    For static ip (you should try this one, maybe your router has dhcp option disabled)
# ifconfig wlan0 XXX.XXX.XXX.XXX
# route add default gw XXX.XXX.XXX.XXX
# echo "nameserver XXX.XXX.XXX.XXX" > /etc/resolv.conf
note: XXX.XXX.XXX.XXX must be the numbers (obviously) corresponding to your router configuration(for IP,GW,DNS), e.g. 192.168.3.110
The first command sets your ip
the second one sets your gateway
the third command sets the primary DNS
Try your connection, this procedure always work for me (on  connections with WPA and WPA2 security protocols)
note: In your output says that wlan0 has no acces point associated, maybe a wrong router password? Try to reconfigure /etc/wpa_supplicant.conf
Thank you! Your post along with some tinkering made everything work the way they should
