Most of the time people forgot to TURN ON the switch to activate wireless.
The switch is located in front of acer aspire, close to where you plug the speaker/microphone.
Slide the switch to the right and the light close to it will start to blink. The driver, old or new
will work anyway.
To update the driver, go to acer web site enter all info and look for the correct driver for broadcom
wireless, or go to control panel/performance maintenance/system/hardware tab/device manager/network
adapters/right click broadcom controler and click Update driver
