I have had this annoying ass problem with my net ever since I got Comcast a few years ago. Basically, the problem is that I can't get a steady connection to the net. Websites and videos like on Youtube don't fully load, and I get disconnected from messenger programs like AIM, MSN, etc every couple of minutes.

I just had them come in today and set up a new modem, but the problem is still effing persisting. I don't know what the cause of it is. Could it be my router and the ports, or is my internet just not fast enough?
