Most of the time my (Comcast Blast) connection works and is fast. However, recently it seems like I've been losing my connection more often (sometimes weekly). I thought it was maybe my modem since Comcast online always says that my connection is fine and there are no outages in the area. The reason I think it's maybe not the modem is that it usually happens on Sunday night. The modem I use is the SB6121 which I bought over 3 years ago. Do you think it would be worth getting another modem or do you think it's my neighbors watching lots of streaming HD porn after night church.
