Can you try this.
1. reboot
2. wait until everything is loaded.
3. Open a console
4. type dig
5. do you see your dns settings ?
if not
6. (sudo) ifconfig;
put the output here for us to see

If its only your wifi connection which is disabled, try Fn F5 or whatever hotkey your laptop uses to enable/disable wireless connections. I had that problem after upgrading a IBM X60 and had to hit Fn F5 just the first time I used it.

Could be a hardware switch.
My laptop has a toggle switch which is placed in the off position will result in what you describe.

I had exactly this problem too. iwconfig returned "no wireless" etc. I thought the wifi card had died or something. Problem fixed with a single key press...
