Ask a useful question and you'll get a helpful answer. What is your question?? Saying "I need help with my network" doesn't tell us anything about what you've tried, what you've searched for, what you're actual problem is.
Please ask an appropriate question, then someone will answer you. No-one has offered any help because no-one knows what your problem is.
I read a tutorial on how to do this, but it involves installing something.
Where was this tutorial?? Post a link to it so others can see what you've tried.
P.S. Posting "Help me" over and over again will almost certainly NOT get you any help! Be specific in your question!
