Do I need the Ethernet Adapter to connect Singtel broadband to Mac Air?

I do not have WIFI and I am using Singtel broadband all the times. Several attempts have been made o access to Internet by inserting the broadband into the USB port of Mac Air but failed to access to Internet. Do I need to set up, if so please email me the instruction or is there an additional cable I need to purchase in order to connect to boardband. Kindly advise. Thank you
