I bought a new Acer Aspire notebook last week, preloaded with Windows 7 Home Premium Atheros AR5B93 Wireless Network Adapter. Download Atheros Wireless LAN Driver for Windows 7 (32/64bit). Free download driver (utilities) for Acer Notebook / Laptop (Netbook) Aspire G direct links. I am thinking of putting one in my Acer to upgrade my Atheros chip. On my Acer the WiFi chip is on the bottom of the computer, less than 5.
