Oh my god PLEASE fix this. I'm dropping in a tournament.
PM sent regarding getting someone out to your house to take a look, but the problem does seem localized to your location (no one else on your street is having the number of T3s you're seeing).
Your levels are good, which leads me to believe some noise is creeping in somewhere. Do you have any splitters on your modem without something plugged in on the other leg? Unshielded (or poorly shielded) coax in the runs? Anything along those lines?
