Re: [TWC] been lagging bad for 7 months

said by bobjohnson:

Signal is too high for d3. Your uncorrectable codewords count looks as if either you have a tap issue (since your tv is acting badly) or your modem outlet is ran through your house amp. D3 needs to be as close to 0db as possible downstream and your upstream looks ok but the snr which you cant see is what can break your latency.

Lets not get carried away. A motorola D3 operating range is +15 to -15. I managed to get mine down to -18 without seeing any difference in latency or bandwidth.

The hop from hawaii to socal looks high.

Rated spec range and realistic operational range are 2 totally different things. Ive installed plenty of these and ubee emtas and really only encounter any issues above +2 and they work well from -7 upward. OPs problem is not an uncommon issue and the usual solution is one of those 2 things generally speaking.

i see... is there a way to get the power levels down? because i have mentioned that to the techs tier 3 techs on the phone and they said no.... they also said i can't switch back to a regular modem with the speeds i have now... i read about these gateways being over senitive and giving alot of problems to your network... just wondering if these things are true...

your help is greatly appreciated!
thanks in advance

Usually there is nothing a customer can do to fix these problems on your end unless like i stated in previous post, your modem cable outlet is running through a house amp... It is most of the time caused by an issue from the pole to the demarc point on your house which is better left to the pros. They are correct in saying that you cant switch back to a Docsis 2 modem with your tier. Also it is not your gateway that causes most issues, if any, but the system in some areas is just not good enough or in some cases just not proper for the newer tech to work well. Anyhow, this is almost identical to what i was thinking to do. Jabbu See Profile is on point as to what you can do in this situation

said by Jabbu:

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.

thank you for the info and im almost positive it does run through my house amp.. and i know the internet coax that goes to my modem runs through a splitter... it's connected to the side that says 51002mghz and then theres a middle one then the right side says splitter... is there anyway to bypass this for the internet but still allow the tv cable to work?
