What do the Network Status lights mean (green network light, yellow network light, red network light)?
green network light The green light means all is OK (ports are forwarded and you are receiving incoming connections) yellow network light The yellow light means that you have no current incoming connections. If this never turns green, this means that your port is not forwarded. The best way to check is with the µTorrent port checker, found in the Speed Guide. If the port checker says your port is open, then everything is most likely fine. red network light The red light means that µTorrent was unable to bind a listening socket. Most likely, this means a firewall is blocking it. It’s also possible that another torrent client is using this port, which will require you to change ports, or not run both clients at the same time.
