Bug description:
  Binary package hint: network-manager

  1) The release
  Ubuntu version:    Ubuntu 9.04   Jaunty  Release:	9.04   64 BITS 

  2) The version of the package you are using
  Package affected :   network-manager  0.7.1~rc4.1.cf199a964-0ubuntu2

  
  3) What you expected to happen
   Estable connection.
   If I kill NetworkManager and connect manually to the network using iwconfig , the problem dissapear.

  4)What happened instead

  Frecuently signal gets interrupted, but not complety disconnected.  
  I guess it is related with the background network scanning but not sure.  I can notice while copying files on local network, watchins streaming movies or with the ping command.  
  Approximatly each 90-120 seconds ,  a 5-8 seconds lag is generated.

  
   -->  Hardware : 
  Dell Wireless card 1515 
  Atheros  AR928X chipset  

    #lspci  | grep Atheros
     06:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

  -->  Drivers :   
  Im not sure.   Clean Ubuntu 9.04  installation  detected my card,  but could not connect to networks until I installed  linux-backports-modules-jaunty-generic  .

    #$ lsmod | grep ath9k
     ath9k                 311092  0
