Title:
  Authentication timeouts on some connections

Status in “linux-firmware” package in Ubuntu:
  New

Bug description:
  Ubuntu 13.10 x64
  Versions affected so far 1.116 - 1.116.2

  With version 1.116.2 I cannot connect to a specific wireless network.
  The network uses WPA2 Personal authentication.  Note that this does
  not happen on all networks of this configuration.  The network will
  allow me to connect once with a given MAC address and then not again.

  The same machine will authenticate just fine when booted into windows
  with the same mac address.

  Using network-manager to spoof the address will work once for that MAC
  address.  When I downgraded from 1.116.2 to 1.116, the hardware mac
  address again worked once, then not again.
