Hi!

The problem still occurs on latest karmic kernel with 5300AGN:

08:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235]
 Subsystem: Intel Corporation Device [8086:1001]
 Flags: bus master, fast devsel, latency 0, IRQ 30
 Memory at fa000000 (64-bit, non-prefetchable) [size=8K]
 Capabilities: <access denied>
 Kernel driver in use: iwlagn
 Kernel modules: iwlagn

The described workaround (disable wireless in nm-applet, modprobe -r iwlagn, modprobe iwlagn, re-enable wireless) usually works for me but occasionally I had to reboot because modprobe -r crashed the module.
