Title:
  rtl8192ce fails to load firmware

Status in “linux-firmware” package in Ubuntu:
  Fix Released
Status in “linux-firmware” source package in Precise:
  Fix Released

Bug description:
  Ubuntu  12.04.3 LTS
  linux-firmware 1.79.6

  Wireless for Realtek rtl8188ce, based on the module r8192ce, is broken
  on kernel 3.2.0 since arround release 40.

  The error message in dmesg  is:
  rtl8192ce:rtl92c_init_sw_vars():<0-0> Failed to request firmware!
  rtlwifi: rtl_pic_probe():<0-0> Can't init_sw_vars.
  rtl8192ce 0000:02:00.0: PCI INT A disabled

  Possible cause:
  I figured out that it is probably broken, because of updating the drivers in the kernel (see http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/?h=linux-3.2.y&id=e6deaf810cc4b6437d55179660776e131ac059df&qt=grep&q=rtl8192ce&showmsg=1) without updating to the new firmware. That firmware is never added to the linux-firmware package. (rtl8192cfw.bin dates from 2010).

  Working solution:
  Simply copying the firmware, downloaded from the Realtek website to /lib/firmware/rtlwifi makes wifi work again on kernel 3.2.0-54-generic-pae

  Link to the package, containing the firmware:
  http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#2722

   Please add the new firmware to the linux-firmware package.
