Lost internet after update, crash and restart

[aneblanc]

I did a routine update with the update manager. 2 updates were not installed Linux kernel headers for version 3.2.0 on 32 bit x86 SMP. Update manager says thepackage system is broken. I restarted ubuntu and everything seems to work except that I have no internet connection anymore. Please help

I am able to connect to the internet through wire. I still don't know what to do to restore the wireless.
