think thats what i'll do. then use the express to extend the network around the house, (its four floors).
Just 1 more quick question,
Is the extreme a modem/router or just a router?
Thanks 🙂🙂
All the airport units are routers, not modems. I use an Extreme base station as a router for my house-wide ethernet system. I plug the cable modem into the AEBS via the ethernet "in" connection, then have a 16-port switch connected to one of the ethernet "out" slots on the AEBS. This switch feeds the all the wired ethernet connections around the house. The AEBS is also set to broadcast wifi.
I also have a Time Capsule attached to one of these ethernet connections and use it to expand the wifi network. The TC is plugged into the wall, and I connect to it, via ethernet, my iMac and a printer. In this way, everything that's fixed is hard-wired via ethernet, but I also have a broad wifi network for my laptop and iPhone.
One further note: if you want to expand the dual band wifi network around your place, you'll need two Airport Express units for each area of expansion as you have two bands. Only Time Capsules (afaik) are capable of broadcasting in two bands simultaneously. The Express and Extreme units can handle both, but not at the same time.
From my own experience, the 5GHz band has a notably shorter range than the 2.4GHz band, so you might want to experiment to see where you need to boost your signal and for which bands.
CORRECTION: Extreme base stations are also dual band. Express units are not.
