signals look pretty much where you want them to be down the middle, you can inquire about your upstream snr calling tier 3 techs if you want to be sure.

You're not the only one. My connection drops and modem reboots every time I upload a large file. Been happening for over a week now. Be prepared so spend weeks fighting with Time Warner to fix it.

Tomorrow I shall be bitching at Time Warner over the phone for the THIRD TIME about this.

Signal levels look about as good as they can get. Downstream SNR is fine. You can't see the upstream SNR, which you'd have to talk to a tier 3 tech about.

Your problem is likely due to failing DCC (dynamic channel change) requests. When you start doing heavy uploads, the CMTS may try to load balance you to a different channel. This should happen seamlessly, but something goes wrong and you fall offline.

The post by AnonFTW in the thread I linked above suggests that it's a problem in the CMTS (on TWC's end).
