I have a Macbook air. I use a Netgear WNDR 3700 router. I have a Seagate 2TB USB drive attached to the router. I reformatted the drive to Mac Extended (Journaled). When connected directly to the Macbook, everything works fine. Read, write, delete, etc. When connected through the wireless network, I can read but that's it. I cannot delete or write. I'm told I do not have permission. I'm told I have "custom permission". Any ideas? Thanks!
