I can connect to my USB drive plugged to my lower USB port of my WL-500gP router via my imac using finder/go/network....but I can only copy 1 file at 1 time and comes up with an error saying I do not have sufficient rights. I have no problem using XP. I called Asus and they said OSX is not supported. Is that true? Need help urgently! In addition, any way I can use download manager from MAC? I am new to this router and imac so please help!
