| [NV] Internet keeps dropping My internet keeps dropping. It never disconnected before, just started some weeks ago. I'm currently using the SB6120 and I tried another modem for a month and I didn't DC. The SB6120 also worked perfectly for months and months prior to the disconnects.

The modem lost it's bonded channels so I rebooted it and they came back. If you keep having issues it may be necessary for a technician to come out and do some further troubleshooting. |

Made a thread about this couple of days ago. Happening again as I type. Connection keeps dropping ever 3-5 mins. |

| Sounds like we would need to schedule a service call for you. Please email us at Coxhelp@cox.com with a copy of your post, your address, a good contact number, and dates and times that you would be available for an appointment. |

1 edit | (This is the OP)I emailed Coxhelp@cox.com and I'm not getting any replies. Can someone send a tech over or something.... I'm pretty done with these disconnects. |
|
| did you try call the local support number? |

I apologize for the delay replying to your email. Your modem does seem to be having trouble holding the bonded channels, but aside from a high TX it's not reporting any obviously bad statistics, so a service call would be the best option for the tech to see what we're missing or determine if it could be the modem itself. I've emailed you back about this in a little more detail.

| Well the downstream signals are fine, but will say the upstream power level concerns me a bit. As around 50db is close to max for bonding, and the warmer the weather gets, the higher that upstream power level will go. |
|
1 edit | I believe the tech said that he was able to stabilize one of the signals but couldn't fix the other one, I think he was sort of not experienced (his supervisor? was giving him directions on phone most of the time). What should I do? |

Well you could just let it be, and if you start having issue's once it start's getting hot outside get it looked into. I just know your right at/close to the max level on the upstream power level. Which it can cause is your connection to be unstable, and modem reboot's. So really at this point just keep an eye on it, and see how thing's go. But if issue's continue or start happening once summer comes, give cox a ring, and have a tech come out to get the upstream power level's down. As you really want the upstream power level around mid 40's, because then once summer comes the possible 2-4db increase will still have you under 50db. |
