This makes it clear that your problem is that the bitrate of your stream is exceeding the capacity of your network.  Your ONLY solution to this is to either use a slower stream, or get a faster network.  (And you should not be streaming over TCP (unless you have a firewall - between the server and client - that blocks UDP packets; streaming over TCP just makes the situation worse.)
