you are still having network issues. your plex setup looks like it correcting maps using UPnP but then the network interface looks like it is flapping ( network is unstable) I am not familiar with the netgear router that you are running plex on, however it seems to be having major problems with maintains a stable network for plex, has the router firmware been updated recently or is there some process using all the resources on the netgear?
