Kinda new to Ubuntu :)

I don't have any knowledge about programming or tech stuff so, please go easy on me :).

I've decided to wipe my Windows XP os and decided to have ubuntu 12.10. It worked fine for a week then, my laptop suddenly lost the ability to connect to a wireless network. A notice will constantly pop up and ask for my WPA passphrase. Tried to type the correct password but it can't connect. The same notice keeps on popping up.

P.S. I've made sure the wifi toggle on the laptop is on.

The Specs:

  • Intel Pentium M 740 (2MB L2 cache, 1.73Ghz, 533 Mhz FSB)
  • Intel Graphics Media Accelerator 900
  • 60 GB HDD
  • 1.2 GB DDR2 RAM

Network Controller : Intel Corporation Pro/Wireless 2200BG
