Dear various parents, grandparents, co-workers, and other “Not Computer People.” We don’t magically know how to fix everything.

First of all, this XKCD comic will make you just as good as I am at helping you figure out how to do things I have no idea how to do, like wrapping text in Photoshop. Second of all, the article this post’s title links to will actually make you better than I am (well, until I start consulting that chart) at correcting wireless internet problems.

Although you might want to download the .pdf version, available below the “Related Articles” section, so you can consult it when your internet isn’t working.
