acrobat says I have no internet connection when I try to convert a pdf file to wood

Are you trying to use ExportPDF from within your free Adobe Reader? If so, try to upload your PDF file directly to the online service (which Reader will do in the background, so it's using the same mechanism), and then download the resulting file. You can do that by going to this link in your browser: https://cloud.acrobat.com/exportpdf - In my experience, using the online service directly is much more reliable.
