If the task is too complicated perhaps you should discuss with your project supervisor or tutor. Doing your homework benefits no one else here.
Suggest you read the technical manuals for your modem and microprocessor thoroughly, and then apply your knowledge of networking, sockets and the HTTP protocol.
