Okay, this is completely not a Mac oriented question, but I was hoping someone knowledgable could point me in the right direction. In my master bedroom, I have a port in the wall for ethernet, as do all of the rooms. Downstairs, I have a master box that all of those cables come into and I can't for the life of me figure out which cable goes to which outlet and I wasn't left with a map. What is the best way to create that map? Is there some tool that I can connect to the master plug and then attach to each cable to figure out which one it really is (and thus be able to create a map?). Thanks ahead of time!
