Trying to connect to a RealTek Router
I am attempting to connect to a RealTek RTL8191SU wireless router from my Acer All-in-one Aspire Z3100-U3072. I am currently running Ubuntu software. I am not able to find my wireless connection. I have gone to the network connections panel in the top right hand corner (logical thing to do) and pressed "Add new Connections" or the equivalent. I typed my network name and included that it is an unsecured network. After completing these steps I was unable to connect, a little box pop'd up saying "network unavailable you are offline". I am stuck, if someone could walk me through this process that would be greatly appreciated. Thank you.
