Title:
  No Wifi on Xubuntu 12.04, Intel Centrino wireless-N 1000

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Acer 1810 TZ; wifi was ok on my previous installation(Ubuntu 10.10).

  Fresh install of Xubuntu 12.04, fully updated : cannot connect to my
  wifi network (Freebox V5)

  I have seen here several bug reports that seem to challenge this chipset (centrino wireless-N), but nothing identical.

  Within two hours of testing various (including deactivating wifi N), it hung the network twice for a few seconds (the password is then OK).
  He will keep searching and asking for more network password regularly (WPA-TKIP).

  As this bug affects (X)Ubuntu 12.04, it is not possible to use it on my laptop.
  I have not found any workaround for this problem.
