My eeePC Ubuntu (9.10) wireless connection stops working after returning from sleep or hibernation. The only thing that helps is restarting the machine.
Is there some way to reset networking without restarting the Ubuntu? I've already tried commands like
sudo ifconfig wlan0 down sudo ifconfig wlan0 up
but it doesn't help. I have this problem for some months now and I couldn't find any good answers by googling around.
