A little tip for home networking. If all you plan to do is throw one or two devices on wifi, browse some web and maybe watch a little Netflix, an off the shelf router is fine. But if you want a network that is going to work when you need it, and almost never need fiddling after you set it up unless you make changes, absolutely go with secondhand enterprise equipment. It's harder to set up, it won't do anything when you first plug it in, but it just... stays working.
