Hi, this might not be quite the right place to ask this question, so please forgive me: My home is wired for Ethernet in every room. I am buying a Time Capsule and also an Airport Express to increase my wireless network. I do not want to simply extend the network, as I understand it will reduce overall speed. The internet cabling enters the home at one point, in the laundry room. Big gray box/service panel. Can I simply install the modem in this box, thus making every ethernet port 'hot,' and then plug the time capsule in at my desk, and the express across my home in the family room? Thanks!
