You have a cable or connector problem. Your forward path power should be at 0 dBmV instead of -7/8, and your return path only shows 1 channel bonded instead of 3 or 4 channels, and it happens to be at the upper extreme. It should be around 37 to 40 dBmV. The single return channel is most likely what is causing the problem. Time to call in a tech to check out the external cable and connectors. |

Datalink: I don't think dallas1 has give enough information to make that conclusion. Tech details here: » Adelphia High Speed Internet » FAQ: Acceptable cable modem signal levels. . In all cases his signal stats are within normal operating parameters. The forward path is great. The return path is high, but still has some margin before it is too high. I do agree that an Oshawa location should probably have more than one upstream bonded. It would be good to better understand the disconnection pattern dallas1 sees. Is it time of day related? Does the modem reset? Does the signal degrade before/during a loss event? What do the BERs do? |

The signals are definitely not right. First dallas1 should factory reset the modem. If that doesn't help, check the cable line. There should never be more than 1 two to one splitter between the modem and where the cable enters the home. Describe to us how the cable runs, and we can recommend things. If it isn't that easy, they'll need a technician to take a look. said by Datalink:You have a cable or connector problem.

On the downstream, anything in the +/-10dBmV range should be totally fine. On the upstream, 50dBmV is officially fine, but it is not a great sign. On top of that, dropping down to only 1 upstream channel is a huge problem. A lot more here: » [Cable] Maximum Acceptable Cable Modem Upstream Signal Level |

Hello Dallas,
I've gotten your PMs, I'll take a look at them now and reply back. |

Ever think i lost internet i lost internet for the whole day the other day it been like this every time i reboot the back it give me 3 return path back then go back to one |
|
|
I've replied to PMs regarding both issues you're concerned about, please reply when you can with the information I need and I'll see what we need to do resolve your connections issues. |

Looks perfect. I'm assuming they removed the unauthorized devices? |

If the OP gets a chance, I'm curious what root cause was determined to be. The last couple of days I've noticed my upstream signals slowly creeping up at random until I see T3 timeouts and eventually the T4. My upstream used to sit around 45dBmV but have been hovering around 49 lately and when the issue happened was as high as 58!
Nothing in my home has changed, it's about 10 years old so I'm leaning towards my modem, or something on the line between me and the CMTS. There is no rhyme/reason to when it happens. |

they gave me a new splitter cable line was cut inside the house and they remove the splitter that was in the cable box to. when the guy gave us cable he hook up the cut wires still got cable. And everything still hook up the way is it just new cable line and splitter and he remove the one from the cable box |

Interesting. I've noticed a lot of work in my neighbourhood lately on both the fibre coming in as well as new homes going in around me where the network being expanded. I'll keep an eye on it, perhaps they hosed something up in the nearest tap or something. Thanks for letting me know . |

Sounds like you've your cable issues resolved now, we'll followup in a week to make everything is OK. |
