Netgraph help

[TurbanError]

Hello, I am experiencing a problem with my netgraph/interwebs.  Inconsistently (but lasting usually a couple of hours) I will experience moments where there are lots of packet loss (black spots on my netgraph).  Usually this coincided with internet troubles (either my ping would get huge or my download speed would drop and stutter on speed tests).  I have had comcast over this entire apartment, and they have rewired everything from the street to my modem (which was replaced last week). 

Now, I don't seem to have any internet troubles 12 down 2 up and I am still having trouble with urt (again inconsistently).  FPS doesn't seem to make a difference.  Any ideas on how to improve this?

try, even though its not fps related.

netgraph-wise, do you get a set of black bars, then return back to normal?

Its more scattered and random black bars.  Originally I thought it was noise in my connection but I think I have ruled that out (barring comcast just sucking in my area).   Magically the black spots have now gone and my connection is good again.  Maybe its time related and congestion on comcast.

well since you live in an apartment that people share the connection, thats a problem. Also, check at what times does it black bar.
example: you see more black bars while playing in the afternoon then at night.
