So, I have been working all day on this and can not figure it out. Here's what I have and how I hooked it all up: Cable Modem to Linksys router (acting as a switch/spliter) Linksys router has the airport express plugged into it and a mybook external hard drive I can not see the external hard drive on the network. When I hook it to my computer via ethernet cables I see the drive fine. But, when I hook it to my network I can't see it. It only has ethernet hook up capability. I downloaded the new firmware from apple for the airport express and that didn't help. Does anyone know how to make this work??? It is driving me MAD!!!!! Thanks for any help and Happy Thanksgiving!
