internet packet loss

for the past week i've been having problems with both of my modems dropping packets. for a couple hours it will be fine then there will be a bunch of packet loss with huge spikes in the ping reply times. when this is happening i will be kicked from any online game and websites stop loading. i can watch the uncorrectable codewords jump by the 1,000s. i also noticed a new 3rd bonded upload channel that wasn't there a couple days ago. its status is set to other instead of success like the others.

i have 2 modems/separate internet accounts in my house and this is happening on both modems with multiple computers. i hooked one of the modems directly to the line that comes from the drop outside and pluggeg a computer directly into the modem. no splitters or routers just directly to the comcast line and i still had the same problem. this rules out the problem being with the cable modems, computers or any wiring in the house.

how do i get a knowledgeable tech or someone who has a clue at comcast to fix this? last time i had a problem like this it took 10+ visits and months (not an exaggeration) for them to finally find the problem at the pole. i don't feel like spending another month wasting my time trying to get this fixed. i know exactly what's going to happen. i'll call comcast and they will say they need to send a tech. the tech will come out and there won't be any packet loss for the 20 minutes while they are here. they will either say they don't see a problem or will try to blame it the modem/computer and wiring.

thanks
