That fixed the problem. I saw the other thread and remembered the first time it crashed was when I was renaming all the "unknown" devices so I knew what they were, and I went to get my switch to get the MAC off it. I didn't even think it could have been caused by a single device (categorization) and thought it was some overload issue. 
 
I just hope the installation of older firmware and current firmware a few times did no damage.
