I FORMATTED MY DRIVE AND AFTERWARDS CAN NOT GET ACCESS TO THE INTERNET

That's because if you formatted your hard drive and reinstalled windows
you need to install all the drivers for the hardware.

Chipset, video, sound,lan,(ethernet) modem.

Right now the computer is running on windows generic drivers.

Go to Acer's website and download all the drivers for this model.

Start here and pick your model.

Hi,
If you have done a clean format of the HDD might as well you have to install the drivers especially for your internet , if you dont have the cd just have another computer that can logged to internet and download the driver here's the site link: http://support.acer-euro.com/drivers/notebook/as_5600.html
if after installing you still don't have the connection contact your ISP provider.
