Internet dropping every 20 mins or so daily all day.

I have been experiencing this problem for a while but at this point its getting really old.  Checked modem event log this is what I received:

 I have a arris 6190 and nighthawk x6 router.  I unplugged a splitter and it helped the Downstream power levels but now it is direct wired and these are the results.

thanks
