tested the suggested mainline kernel. wireless is not unclaimed with
this kernel (recognized with lshw) but wifi is not working properly,
icon always flashing and requesting for the wpa passphrase but never
connects. also bluetooth not available! to have wifi and bluetooth
working i have to use again 3.2.0-54.82 kernel.

i got some error messages installing the mainline kernel headers,
probably about wireless modules, so i'll attache file make.log

afaik the bug is not fixed in the mainline kernel

Title:
  Kernel 3.2.0-55 is missing driver rt2800pci for Ralink RT3290 Wireless
  (unclaimed)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Description:	Ubuntu 12.04.3 LTS
  Release:	12.04

  On a Notebook HP 650 with Ubuntu 12.04 LTS 64-bit i received updates for kernel 3.2.0-55-generic (exactly 3.2.0-55.85)
  and starting the notebook with that kernel results in unavailable connection, no wifi.

  Starting from grub with previous kernel (3.2.0-54.82) solve the issue.

  in short:

  with 3.2.0-55 kernel, wireless is UNCLAIMED

  with previous kernel 3.2.0-54 is working properly and "sudo lshw -C
  network" from terminal report:

  PCIe  in future kernel release

  thanks.
