Title:
  WPA2 with TTLS and PAP connection drops

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  I have been experiencing difficulties to connect to my lab network and
  to eduroam. These are WPA2 networks with TTLS and PAP authentication.
  The signal strength is almost 100% (but I am usually receiving from
  different closely located spots, so the system might be trying to
  connect to the more distant ones instead).

  When trying to connect, the nm-applet displays the "connecting"
  animation for several minutes and I am repeatedly asked for my
  password, as if connection attempts were rejected due to wrong
  credentials. It can sometimes take up to 20 minutes to achieve a
  connection.

  Then, it regularly drops or "dies" : I am still considered connected,
  but I cannot send or receive data. I have to get through the above
  mentioned connection process again. Today, connection drops roughly
  every 45 seconds, but re-establishes after 60 seconds.

  Concerning eduroam, which has spots in many academic buildings
  throughout France (and more), the problem seems not to depend on the
  spot (it happened in several different towns).

  I do not seem to experience this kind of problem with lower security
  networks (although I am rarely connecting to them), so it might be
  related with wpa_supplicant.
