TWC came out today and found the coax cable was badly damaged out on their pole. They repaired the cable. We were able to get them to swap out our old Motorola SB5101U for a brand new Motorola SB6141. New stats are below:

Anything I should keep an eye on, or do these stats look reasonable?]]> http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27767127 Wed, 28 Nov 2012 01:21:19 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27762016 http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27762016 Mon, 26 Nov 2012 16:42:19 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27761231

It's 30db on the channel that works; it may be much worse on other channels. If he has a HDHomeRun (network tuner), then he could test the SNR of every channel; but short of that, a TWC minion would have to come out and test.]]> http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27761045 Mon, 26 Nov 2012 12:04:12 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760086
An SNR of 30db is fine, this depends on the quality of the plant; the leg you are off might just be noisy.

Pay attention to the lights, when it goes out which lights specifically go off? Downstream is the forward and first to be established. Upstream or return is the second. Online is the final one to go solid, indicating the config has been loaded and the service should be ready to go.

PC activity is just a lan link indicator. It is solid or blinking in normal operation. If this light goes out while the others continue to stay on this indicates a local issue like your router going out or a bad ethernet cable.

If the TWC system shows you losing sync twice that might indicate a more local problem. Just food for thought]]> http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760086 Mon, 26 Nov 2012 01:44:09 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760032 http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760032 Mon, 26 Nov 2012 00:38:33 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760010
Your SNR would suggest the signal is too weak, or too noisy. TWC is lying when they say nothing is wrong.]]> http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27760010 Mon, 26 Nov 2012 00:19:53 EDT http://www.dslreports.com/forum/Re-TWC-Frequent-disconnects-TWC-claims-everything-is-fine-27759992 Frequency: 675000000 Hz Locked

Any suggestions? Here is the log from the modem.
