Bad Internet Connection

Hello All,

 

Ever since the night of Monday April 10th, I have been having issues with my internet connection. My modem (Arris SurfBoard SB6183) rebooted randomly, and ever since then, any attempt to reboot the modem takes upwards of 10-15 minutes to establish a connection, and the 3rd light from the bottom is now a solid green light instead of solid blue (1 channel instead of bonded upstream channels).

 

In reviewing my modems status page, I am seeing the following:

So as you can see, only one upstream channel, and reviewing the signal levels information page, it appears that the signal power is critically high, but I would like for someone here to very what I am ready is correct, if I may be missing something else, and possibly one of the TWC/Spectrum Reps on here to assist me in figuring out what would be the next steps to get this issue resolved ASAP. I can post whatever logs I have on the modem as well if needed.

 

Thanks!

Did anything happen on Monday night which would have caused a change, such as storms?

 

Have you made any changes to your installation?

Re: Bad Internet Connection

Hello dstoffa,

Thank you for the response.

No changes have been made to my installation in close to a year, if not more, and I do not remember any storms occurring Monday night. The modem just rebooted by itself, with no power outages occurring.

I did call into the TWC/Spectrum Support line yesterday about this, but the rep wasn't as helpful as I would have hoped. She said something about them possibly pushing an update out to the modem that night, and currently seeing the modem as online (which it is), but the performance is less than desirable, especially for someone like me who games a lot.

Re: Bad Internet Connection

corroded center wire, bad splitter, Open splitter ports, center wire too short. It must be shiny copper and extend 1/8" beyond the nuts.

 

Re: Bad Internet Connection

As of this morning, I now have no Internet connection at all. A reboot of the modem does nothing. I've literally tried everything that I can think of, checked every single connection in the the house, and don't see a problem. Can a TWC/Spectrum employee please assist? Here is my modem status page and event log.

Re: Bad Internet Connection

[ Edited ]

checked every single connection in the the house...

 

There should be only one 2 way  or no splitter between the outside line to the street and the modem.

 You have a horrible upstream signal level issue and will need twc out to fix it if not obvious.

 It cannot be fixed over the phone . You need to see 4 upstream channels and tx levels on them lower than + 52 dBmv.

 

 

Re: Bad Internet Connection

I'll be giving the support a call again and hopefully get something scheduled. At the moment, the connection is working, but still one upstream channel, so the connection is pretty spotty. Thank you for the information.

Re: Bad Internet Connection

Make sure the center wire is shiny copper and extends 1/8" beyond the nuts on all connectors... It could be out at the pole and needs twc to replace.

could also be a corroded grounding block on the side of the house
