When using certain programs, I loose the internet connection. After a brief period it will come back on line and if the same program is active, the process will repeat untill I shut down the offending program. The error message presented is "local area connection network cable unplugged". Everything works fine as long as I do not start certain programs. The error is self correcting, but interrupts the communications that were occuring at that time. This is a new problem that arose after I optimed my cable modem settings. Does anyone know what I have done so that I might correct this situation?
