I am revising my home network and have a question about the ordering of devices and whether or not it matters. Currently, I have my comcast modem running into an Airport Extreme. There is also an ethernet switch connected downstream with other devices connected. The problem is that the modem/router is currently in my home office which has poor wireless distribution to the house. I'd like to move the router to a better location, but I need several ethernet ports in the office. Here's my question: Can I connect from the modem to the switch, then to the Extreme, or must the router be the first device after the modem?
