This is from dictation, there might be some funny grammar. 
Your question will be answered shortly, however there are important details you have not mentioned. You want to include some details about where you live and what service you have. Not enough information to invade your privacy, but enough information to help others understand what kind of problem you are having.
In many parts of the United States people get Internet service through one of the cable television companies, such as Comcast. The other providers have similar services delivered over either telephone wires, pay-TV cable, or possibly a broadband wireless connection.
A few individuals had direct satellite, but that probably is not what you are using.
In general, the Internet service provider will set up the equipment for you and give you instructions that are easy-to-follow.
I am wondering how to chew get a piece of equipment for Internet service without getting also the information from the provider about how to make it work?
Each service provider has specific details about how their equipment works. So it's not easy for anybody here to tell you exactly what you have to do.
Please provide some more details annex plane why you did not get a manual or quick setup guide that tells you exactly what to do.
End of dictation.
