I signed up for Ziply wifi and need to set up this new tp-link router. Unfortunately I know almost nothing; my ex-husband used to take care of this. What I do know: I have an Apple Time capsule, a modem, and a cable coming out of the wall that goes to the modem. I don't really know where the time capsule fits into all of this other than it automatically backs up my laptop. Am I giving this up now? What about the cable from the wall?
