Summary: My experience with this Sony laptop was unsatisfactory for the following reasons: 1. The Atheros wireless network adapter (AR9485WB-EG) was essentially worthless. Full WiFi reception was only possible within 10 linear feet of the router. Stepped past 15' and two bars dropped; stepped into an adjoining room and connectivity was intermittent. No driver updates were available from Atheros, and customer support was only via email with a 24-48 hour return contact provision.
