I have been using the board for over a year with no problems until now. I moved HS3 to a new computer, went through the process of installing Arduino files, libraries, and setting the ethernet address, port number in the config, then downloading the .ino file, and finally uploading that file to the board. I cannot connect the ethernet port. The log file shows that no ethernet address is present on the board. I checked the sketch before it was loaded to the board and the address and port number are there.
