Re: [TWC] been lagging bad for 7 months I'm going to stay away from explaining t3 and t4 timeouts, as we all get them.
"Failed to acquire QAM/QPSK symbol timing critical"
This is a downstream issue, more then likely a int. issue since each time you post your signals they look good, yet a TWC tech will have a meter that can test signals the modem isn't going to tell us.
You'll want the tech to:
Run a docsis test and sit on it for 3+ min.
Check BER on all docsis QAMs. MER is posted in your log and looks good.
Have him run a DQI on your line while you chat, this is a over time test and he can leave the meter on for 10-30min to catch any issue.
DQI should be 10 in a perfect world.
If everything is coming up good, ask him to find out the US SNR, and be sure he doesn't pull the downstream SNR. This is something only a tool/website on his computer or a call into tier3 is going to tell him. |
| for some reason the guy came out and said they weren't allowed to test anything speed related... i asked them to do a docsis test they said they didn't have a docsis meter although after asking if they could do any of the tests they did a dqi test to channel 87 and 85 for like 2 mins each and came up 10 i didn't get a chance to ask them for the upload snr before they were already heading out the door... they said the problem isnt their fault.... and that i need to stop calling or they'll charge.... i feel pretty offended that they would deny my requests like taht i've been with them for about 10-14 years and i only recently started calling within the last 7 months and they treat me like im crazy or "if you don't like it beat it" and theres no other internet company i can try so im stuck... |
