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.
