Intermittent connectivity/frequent short outages

I contacted support for this already, but they said my signals look good and I should check my routing & wifi setup locally.  However, in looking more, I've found that the cable modem loses sync when I'm having trouble, which makes me think it's a signal or upstream issue.

 

In the status, you can see there's an 850Mhz band that looks like it has poor signal and a lot of errors.  And on the event log, you can see several MDD message timeouts.  Anyone have ideas about what's going wrong?  The line is going straight from the pole into my modem now to eliminate variables (though the numbers look the same as when I had it going through my splitter).

 

Thanks,

Jesse
