How to Improve the Speed and Range of Wireless network?

[EvaCarey]

I want to know about it. Can anyone help me for this?

As with your question about "essential equipment", again the answer is that it depends on what you need. How much range do you need? How much speed do you need? What equipment do you already have? What is the local environment like (wall/frame type in the building, the distance and number of walls between the router and the computer, the number of other wireless networks in the area)?
