Title:
  Ubuntu 15.10: WiFi disabled on Thinkpad X230

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Dear all,

  Occasionally the WiFi module of my Thinkpad X230 is disabled.

  It occurs without a recognisable pattern.

  Sometimes on a fresh boot. Sometimes on resume from suspend.

  In the indicator icon context menu, networking and wifi is enabled but
  greyed out.

  Switching off/on the Wifi using the hardware switch doesn't solve the
  problem.

  The only working solution is to do a fresh reboot.

  Thank you for any possible help!

  Robert
