[Metairie, LA] Connection dropping multiple times a day.

For about the last week we've been a big increase in the amount of times we're having internet service drop out, followed by the cable modem (S33) auto rebooting itself.  Here's a look at the signal levels after an uptime 2hrs 47mins of uptime.

The downstream power levels should be -15 to 15 but some bonds have lower power, 1 not locked at all and a lot of uncorrectables on those same low power bonds.

There's no splitters on the line. It's pretty much off the pole, through the ground block, through the wall and into the S33 modem.  Been working fine up till a few days ago.

Could this be caused by a neighborhood equipment issue and if so, how could get Cox to actually check that equipment versus just a contractor coming and checking my modem signal?
