Hi gac, I am a MAC user & connected the printer through an Airport Express. Intially its having problems connecting/ communicating with each other, until I gave up & called Apple Support. We found out that the cause was, I have selected "Connecting to another Network" instead of "Creating a New Connection" & the rest is history. The printer is perfectly working Wirelesly - Printing & Scaning. Never tried and set up Fax function as I don't have any land line phone service ( I only have DSL dry loop). I do hope this help.
