I apologize for the problems you have had with the connection. I checked your modem and I see an issue with both the downstream and upstream signal-to-noise ratio (SNR). I also see a significant drop in the downstream received signal the 9th. This doesn't seem to be an area wide issue as other modems on your street still have the same signal levels. This can be caused by a loose or corroded cable connection or possibly a bad splitter. If there is a splitter between the modem and the wall, I would try bypassing that for a little while. Replacing it would be about a $3 fix. If that doesn't help, I would need to have a tech stop by to check everything out at the house.
