Where can I download the newest firmware for Prism2x

[softlib]

Hello,

  I have a linksys WMP11 PCI card and I have already upgraded
  firmware to 1.4.9, In order to use all functions in hostap driver,
  I have to upgrade it to at least 1.5.x.
  Do you know where can I download the newer prism2x firmware
  for my card?

  Thanks!
