I've got an iBook G4 connected wirelessly to the net with an Airport Express. I just bought a "Network Hard Drive" (http://www.lacie.com/us/products/product.htm?pid=10994), that I'm trying to get connected to my network. Unfortunately, Since my modem [motorola, provided by mediacom] and wireless router [Airport Express] each only have 1 ethernet port, I need an ethernet switch [or maybe a new modem/router] to connect my network drive. So, my question is, will my theorized configuration work: Modem --> ethernet switch --> Airport Express -----> iBook [wirelessly] ...............................AND --> Network HD where I'll be able to have the network HD on the same network as the iBook. And, if this setup will work, anyone suggest any switches?
