anon posted : I've been having latency issues as well. My pings are spiking all over the place. When I call TimeWarner they tell me my speeds are fine (which is not the problem anyway) and that my pings are acceptable, which they clearly are not. It's impossible for me to play any online games. I've had RoadRunner for 12 years and this problem has just started in the past few weeks. I've done all the troubleshooting I can. Updated drivers, checked for viruses/spyware, disabled firewall, connected my computer directly to the modem, had a tech come to check my modem, he found no problems but replaced my cables outside anyway and still the problem persists. It definitely seems to get worse during high traffic times (5pm-11pm). Also, my neighbor a couple blocks away has the same service I do and has no problems. Again, my pings aren't consistently high, just spiking.

I'd appreciate if anyone could help me troubleshoot further.

bobjohnson posted : Those are generally the only two things that cause issues such as what you have going on. Usually what happens is there is a tap problem and your signals go nuts and cause all the problems and your amp (which HSI isn't supposed to be running thru anyways) amplifies the problem. Also less frequently, bad outdoor splitters or bad cables. You have covered all the bases on this one.

these are my new specs through a splitter.... it's alot more playable and seems like things are connecting better... but it's still far off from what it use to be... the lag im experiencing is more of like a screen lag feel... like nothings in sync...and it's far worse than before... before i'd be on a two bar and it really wouldn't effect me as much... now i'll be on a four bar on xbox and even host and it lags... the lag is constant and on every game... i've been mointoring my packets lately and i have 0% loss... so im ruling that out..i've tried two different tv's recently one with hdmi cord and another with digital av cables the blue green red one... im planning on trying a 4g le hotspot just to determine if its my isp... or something in my house messing with the signal or wiring and electrical problems etc... i've also been reading about NIC cards? not sure how i'd install that in my router or modem cause im sure road runner has policys that you can't open up their modem... then i've also been thinking about trying dc taps.. cause i notice through the splitter it's better but the upstream power level spikes high to 52.... 49 is the lowest it's been since i've tried the splitter... and from what i understand the directional couplers lower the upstream power level along with the downstream power level...

im not quite sure how to test it directly through the amp or outside at the box if anyone could run me through the steps i'd gladly try that

thanks in advance

kilrathi posted : I recently had same experience with a foreman and 2 techs who were requested to come and try to findout reason for the upstream noise that I am having ever since they implemented upstream channel bonding and 64QAM modulation for upstream channels(2 of them). However, foreman was like "5 % packet loss? and you complaining about this? thats nothing" while the techs were chatting up about baseball game and checking scores on the phone, when I asked if they could at least take measurements on the pole because I am trying to get a plant tech to come and try to trace frequency and possibly find source of the upstream noise they just looked at me and basically the outcome was "deal with it".

I have been customer for over 7 years now and the only person that understands my sistuation and what needs to be done are some of the t3 techs at escalation/digital team that I call, I think his name was Nate. After looking at the logs and upstream stats for my modem he said that basically need a plant tech team to trace frequencies and find where the noise occurs, and that it could also be plant misconfiguration.

But both client relations and techs just giving me runaround now, and after replacing lines to my house twice I am not sure what else to do, issue occuring on the pole or on way to plant somwhere but noone seems to care about fixing it. I guess having most expensive package for internet from tw doesnt matter.

One other thing I considered is getting tw telephone service as this voip service wouldnt work with the current packet loss i have on upstream and that would possibly force tw to do more about this issue, but having to even think about buying service i dont need just to have tw fix the issue is just crazy.

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 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.

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.

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.

Huh? Picking the worst numbers for each channel:

8.5dBmV is pretty well within spec. -10 to +10 is conservative, DOCSIS spec is -15 to +15.
39.9dB is great for SNR.
48.2 is a nice number of the upload level to be at. 40-52 is within spec.
If his modem has been up for any length of time, 28 correctable and 117 uncorrectables is practically nothing.

His lag problems are likely elsewhere.

riot808 posted : i've had roadrunner connection for about 10 years now and only recently started having really bad issues about 7 months ago one day i woke up to play some xbox and noticed my lag was horrible so i power cycled the modem and router i had at the time thinking it would help... but it didn't so i thought to myself well maybe it's just a momentary thing... well i was horribly wrong.... it's been 7 months now and counting and my lag is still persisting... so i upgraded my connectiong to the highest roadrunner offers here in hawaii which is 50mb down and 5 up along with it i upgraded from a regular modem to a gateway motorola surfboard sbg6580 i've been through 3 routers since i had an old linksys then upgraded to a linksys e4200 that one broke after 3-4 months of having it... it just wouldn't power cycle up the lights were all frozen on them even after unplugging for hours... and trying to hold the reset button so i sent that back and got a asus rtn56u which i currently use... i am in the process of returning it for a new one because it got frozen while i was trying to upgrade it's firmware.. this is what the techs have tried... they rewired the coax cable from the modem to the box... they said they found a error in the drop on the streets box... and apparently fixed it... they took 3 splitters off of the cable line... they swapped the modems to see if the one i had was defective... the tech support phone operator also downgraded my connection to 30mb and 5 up to see if that would help... it didn't... so besides all this they just do speed tests now and say im getting what im paying for and they basically wrote me off so i've been trying to read about networking and what i can do to fix it and im stumped and looking for some help.. i would really appreciate any information tips tricks guides... please remember im not so technically advanced and am still learning...

also i noticed theres a huge delay when changing channels on the tv often does this weird pixelation fades out goes black and finally turns to the channel sometimes even has almost a minute delay to the next channel also when i turnt he cable box off theres a black box in the middle and on the boarders the tv is still going in the back... then eventually shuts off... sometimes it doesn't and we've also noticed that channels go missing randomly that we pay for... i don't know if this has anything to do with the internet but ever since my connection got bad the tv started acting funky.

thank you in advance
