I have a monitor pinging google every 10 minutes or so:
Today:
6:51AM: High ping 10.124/9009.496/26666.382
10:30AM: High ping 13.217/4076.301/17779.276
10:59AM: High ping 11.683/8750.443/22807.566

I have tried resetting modem as well.

My network traffic is low to none....

Any ideas?

Ahh. shoot. Going to answer my own question.

It turns out my router was CPU-bound. The firmware I have on it doesn't like Upnp. Its a known issue causing high load. I usually have it off but had to turn it on for COD3... I have since used port forwarding but forgot to turn it off.

I'll monitor but it seems like we are doing good now. Thanks.
