my laptop can't find network in range..wireless network connection always saying no wireless network were found in range even inside starbucks..even if I refresh it..
Are you sure the wireless adapter is enabled ? There's usually a physical switch or a keyboard combination.
Beyond that, as you seem to have guessed, look for a newer driver -- if the chipset brand is obvious go to the chipset maker's site as it may have a newer driver than Acer.
