I need to connect my computer to my mobile hotspot as there is not internet service where I am. When I turn the computer on it sends a message “not connected to internet”. It must have internet before it will open at all. When I click on the internet icon in the lower right corner, the only option I have is to turn on or off Airplane mode. It does not give me any options to connect to the internet. 

Previous to today, I have only used the laptop at home where it is connected to the wireless wi-fi that was selected at the initial set-up. Now that wi-fi is not available.
