I have an existing AEBS but we relocated our office and it was cheaper for me to buy an express then have my ISP come out and move the line for the DsL. Well I hooked everthing up tonight and added the express as an extender with the ability to add wireless clients and all went well. My Mac mini is connected via Ethernet and I added a USB hub so I could plug in my printer and external HD. Printer works great but the Lacie HD is no were to be found. If I connect it directly to the mini it mounts right away so I know it still works. Is there a setting I am missing?
