Louis is watching baseball games streaming online and sometimes the feed stalls. Leo says that's called buffering, and sometimes a packet drops and the feed will wait to see if it shows up out of order. Then it will insert it and move on. Sometimes, though, it just gives up and continues. There are some causes of this, including congestion from a wireless connection. But Louis can get a dual band router and use the 5Ghz band, or just connect to the router with an ethernet connection. The stream will be more reliable that way.
