I just purchased a small netbook unit that has built-in WiFi but the unit does not connect to my home Wi-Fi. I have a Time Warner cable connection for internet and a router to send the internet to my computer in another room. Doesn't this mean that any Wifi enabled unit should be able to pick up the internet signal thru the router. My wife uses a Kindle that has 3G WiFi and it works fine in our home. Any idea why this new netbook won't pick up the signal?
