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.
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.
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
