A friend gave me her Acer Aspire One D250 Netbook. It will only connect to the internet with a wireless connection. control Panel/Network connections only gives that as an option. When I plug in ethernet cord it doesnt connect. I need to connect using ethernet which isnt detected. Device manager shows that the ethernet controller driver is missing as well as SM Bus controller. I can't find where and how to download ethernet controller driver. I need step by step details since I am not super tech savvy. When I go to acer support for drivers and put in my netbook specs it doesnt list an ethernet controller driver for my netbook. HELP please!
