So I was given this router to replace my hub. The router is a D-Link DI-604. I'm having two issues with it, the first being that it seems to randomly like to drop the internet connection to one computer (though never to the other), and the second being that despite setting up connection sharing, neither computer will recognize that it's on a network with another.
I don't know much of anything about networking, and I didn't set it up, but I am, of course, the one that's expected to fix it. Anyone able to help me?
