Comment 22 for bug 567961

I primarily use system connections with network-manager and I haven't experienced this issue. My brother uses user level connections and complained about this issue. We both have Intel based wireless cards. I don't have access to my brother's hardware to test if using system level connections makes a difference or not.

If someone wants to try, there's a checkbox that you can enable when you configure a specific wireless connection. You should end up with a corresponding file in /etc/NetworkManager/system-connections
