in order to use my Airport Express' ethernet port for my network-ready scanner/printer, i bought an Airport Extreme (n). the big project is for me to disable my 327w wireless modem / router (g) that AT&T supplied, use it only as a modem, then use my Airport Extreme as my main wireless router (my Apple TV currently is connected to it via ethernet). please correct me - so in preparation, i need to disable the wireless portion of my 327w while still letting it handle the internet connection (i believe it's a PPPoE connection). does anyone know how to setup the AT&T Westell 327w for a modem-only setup? once i figure out how to do that (!), i should be able to connect the first port of the 327w to the WAN port of the Airport Extreme. then configure the Airport Extreme however i want to. then i can add my Airport Express (g) as a WDS client and enable the ethernet port. right? does anyone have any experience with this kind of setup? thanks in advance!
