I have a friend who has internet coming thru cable into the living to an airport express. We are wondering if he can use an airport extreme as an wds extender in the basement home office, where there is not a cable hookup. The office has several PCs and several printers. Some of the PCs could be wired(ethernet) or wireless to the extreme. Would this situation work? could airtunes be used in the living, and the extreme be used as a print server in the basement? Also would airdisks be supported on the extreme since it is being used as a WDS? Any input is appreciated.
