Power Management problem/ network disabled after wakeup

Asked by Armen

If you set the power management to any specified time to make the PC sleep and you wake the system up the network connection is lost and it does not get retrivrd/connected. The only way to get the connection is by restart. Is there a way to avoid this?

Well the quick and dirty answer would be to shut the computer down instead of putting it to sleep.

The longer answer would be that there are some bugs for this depending on the system, software, and network.
What version of Ubuntu are you using? What is your computer make and model? What network cards are you using? Have you searched https://bugs.launchpad.net/ubuntu/ ?

Instead of restarting the computer you can just restart the network interface:

sudo /etc/init.d/networking restart

This works for me.

If sudo /etc/init.d/networking restart works for you, there might be a way to run that whenever you wake up the system.

Can you help with this problem?
