Thomas, that's unfortunately unlikely to change the behavior much. What's breaking is the supplicant, before NetworkManager.
I think this is an issue at the kernel level with however the driver might be designed; but I'd like to make sure it's not an issue with wpasupplicant first. Could you please try to see if you get the same behavior on an open network? Without WPA, wpasupplicant doesn't need to be started and maybe the connection remains up in this case. If it does, then that would be likely looking at a wpasupplicant bug. If the connection dies anyway, then we're indeed looking at an issue with the kernel driver in use. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/879173 Title: Wi-Fi connectivity interrupted by CPU high load; once load is reduced NM reconnects -- ath5k Status in “network-manager” package in Ubuntu: Incomplete 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.
