I'm on Ubuntu 12.04 LTS. With the previous kernel everything was okay — until today's upgrade to 3.2.0-24-generic-pae. The device network tools show that my WiFi card is in an inactive state.

How can I enable it?

These commands don't work:

sudo ifconfig wlan0 up
sudo /etc/init.d/networking restart

The last one returns some weird errors, brackets, tildes, ampersands like in some kind of a loop.

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
