Okay. Still don't know what happened exactly but this quick hack works in my case. My wireless network card is "Broadcom Corporation BCM4312 802.11b/g LP-PHY". Whenever the wireless gets locked up after idling for some reason, I do:
Code:
sudo /etc/init.d/network-manager stop
sudo modprobe -r b43
sudo modprobe b43
sudo /etc/init.d/network-manager start
Basically it just reloads the wireless driver "b43". I installed the driver via package called "firmware-b43-lpphy-installer" in repository. I guess the glitch may have something to do with the driver.
