My cable company recently gave me a Ubee modem/router. And I've got an Airport Extreme. I can't seem to figure out how to get the AE to speak with the router. First question, though: I'm using Time Machine to back up to a WD external drive. Does Time Machine have to go through an Airport, or can I plug the WD into the usb port of the Ubee and just do away with my Airport? (I did try this, and Time Machine didn't work without the Airport.) Second: I thought there was a utility for setting up a network, but when I go to network utility or airport utility I don't see anything that allows me to get the two routers to speak. Or maybe I'm just more confused than I realize. Any help? Third: If I don't need the Airport Extreme for backups, can it be used to extend the range of a router? That is, at my parents' house, they have a Linksys router in one room. They don't get very good wireless upstairs. Is there a way to use the Airport Extreme upstairs to have it pick up and amplify the signal from the Linksys? (I'm pretty sure there are other gizmos that do this, but if I've got an extra AE . . . .) Thanks in advance.
