Ping & lag spikes 1 hop away for last week or so. see pictures

high ping and lag spikes like this make gaming impossible.

10-45 minutes at a time and you are dropped from the game

as you can see from the graph and ping this is happening ONE HOP away from my modem.

the uncorrectables were cleared up by disconnecting and reconnecting all of the cables from the modem to the drop.  now they are back on a different channel
previously downstream channel 13 and 20 were having more than 50 percent  uncorrectables
channel 13 is still low, but atleast it is staying locked without errors.
now channel 19 is reporting the errors and logged drops.

i know what youre going to say, is there a splitter?
yes one splitter, that is my next step to bypass that outside the house.

but there has previously been absolutely no issue before a week ago.
a week ago my modem disconnected for 3-4 hours -comcast outage?- before that a week before there were some storms in the area.
before the outage there were absolutely no issues at all with connectivity
