Re: [VA] WOW!! new sb6120 modem speed
Yes, 33db is below what we consider the acceptable value of 35db but if you're not experiencing any service issues I would leave it be for the time being. |

GREAT for the 20 seconds you had it Well your wrong, if they just started testing D3 in his area, most likely they are letting him pull 50 down, and around 5 up. So anything above that mostly is powerboost but the steady 50/6.25mb's a second down is real. We all know speedtesting sites measure totally different. |

said by madden2k5 :Yes as coxtech1 has said no changes in upload speed really, there will be changes on down the road for upload, but right now they are more focus on faster download speeds, since upload bandwidth cost more. And upload can be fully utilized unlike downstream which goes largely unused.

Is there any difference in latency (ie. VoIP) from D2 to D3 ?
Thanks,

Edit: wth you mean latency for VOIP? Voip doesn't take shit to run, so any speed service from cox should run VOIP great. |

| I picked up a Motorola SB6120 as well to replace an Arris D2 modem. Blue light on Motorola came on right away. Powerboost speed in Speakeasy test went from 20->32mbps downstream, so not as good as the 50mbps that bryan69u is getting. Modem stats, however, went from 37dB -8dBmV on the Arris to 34dB -12dBmV for each of the 3 channels on the Motorola. Basically, it goes below the acceptable 35dB/-12dBmV threshold during the middle of the day (seems to correlate to heat?) and then goes above the threshold at night/early morning. But I don't notice anything wrong with the connection when it's below the threshold.
What are the signs that being below the acceptable threshold is actually causing a connection issue? Does the modem downgrade the speed like DSL modems do? |

1 edit | Well them level are rather weak, and maybe you need to get a tech out there to look at your line, and see if a line is bad or maybe bad splitter or too many splitters. |

| Ira, what i meant was, I think it could be up to 5ms better, but it could work both ways. I just think on the better side since D3 is gunna use bonded channels, which means things could be accessed alittle faster being its pulling from more then one channel. |

USA | bryan69u - Have you tested your non-Powerboost speeds before and after putting in the D3 modem? I found the only difference was the bigger Powerboost in the first few seconds, which mainly just generates nicer speedtest results. |

Just installed a SB6120 here in Falls Church. PC-to-Modem direct connection I'm seeing 53 Mbit down, 7.3 Mbit up. 
Modem shows 3 bonded downstream channels... all with excellent power readings (0,2,2 dBmV) and good S/N (36, 38, 38 dB). Impressive.
Its a shame my older hardware firewall can't support that throughput. It tops out at about 40-45 max.

Thanks for the heads up on D3 available to me in NoVA. I thank you! A pleasant surprise indeed! No problem im happy things are going good for you after that D3 modem upgrade. I have been patiently waiting, but also probably driving CoxTech1 crazy with questions about D3. Foreal the faster speeds are nice, but i mainly want it for the more steady speeds we will see with bonded channels. Because we all know that cable's biggest weakness with the overloads on one channel for internet. |

| Pretty much same here. Although I'm assuming that with multiple bonded channels you would have higher reliability too. If signal goes weak or noisy on one channel, you won't lose connectivity... You may see loser speed, but the connection should be able to operate as opposed to losing sync. Of course with only one upstream channel at the moment, you're still subject to upstream signal issues. Correct me if I'm wrong on this.
