Title:
after suspend/resume wlan0 missing
Status in linux package in Ubuntu:
Incomplete
Bug description:
After calling pm-suspend or closing the lid or using the GUI button
for suspend and then finally resuming by pushing the power button on
my laptop, my wireless card is aparently disabled. More than that if
I use ifconfig to attempt to find the interface, it has be
unregistered from known network interfaces (i.e. wlan0 is missing when
you do ifconfig).
I have also tried the excercise described here to help with isolating the issue: https://wiki.ubuntu.com/DebuggingKernelSuspend
I have also tried to manually use modprobe -r with no success.
