Title:
  Wifi connection dies with CPU high load

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  I've noticed that, when I run some application which is CPU-intensive
  such as compiling and doing some number crunching, the wifi connection
  just dies out and stays dead as long as the CPU load is high.  Once
  the CPU load dies down, the network manager suddenly is able to re-
  establish the connection.  This happens both when a single CPU core is
  taxed or when I run multiple demanding processes.

  I'm running Ubuntu 11.10, but this problem was already present in
  previous Ubuntu releases.

  The expected behaviour would be that the wifi connection didn't died
  when the CPU got taxed.
