I have a Satellite l875-s7308 and I'm trying to make it where I can go online using Ubuntu 12.04 that I installed. Ethernet connection was working, but while trying to get WIFI to work on it I must have put in some command that now keeps me from getting online at all. I need some help and please talk to me like I'm five. I'm new to Ubuntu and this whole new way of doing things. My Mom hates Windows 8 which was on the computer previously and since I've used Ubuntu on an older pc with no problems I thought she would like the switch. However, that will not be the case if I can't get the internet to work on the laptop. Any help is greatly appreciated!!
