Secure home wifi

For this week's project, you are to first conduct an Internet search on "How to Secure Home Wifi." With those results, you are to create your own tutorial that you could give to your family or friends on how to configure your home wifi to be secure. Your tutorial should include step-by-step instructions on how to do it. Include technical settings for a home router as necessary. Images and graphics showing steps are encouraged. 
Any information or picture taken from a reference must be cited. Also, you must be able to explain your instructions, so no copying from your Internet reference. 

----------

Your tutorial should be at least two pages in length.
