I got a 56K modem which produces an average of 48K but when I try to listen to streaming radio stations such as WLYF (my favorite station) it constanting buffers over and over again to the point that the station is unlistenable. I try at all times of day even at 3am in the morning it buffers. One time I got a unbuffered connection for 45 minutes. How do I improve my connection without getting high-speed?
