    Hi, thanks for providing the modem log I see a few timeouts there, are there any splitters or amplifiers being using on the connection? I checked the signal levels based on the MAC address in the modem log and I am seeing some issues with the signal to the modem.

    Thanks for the reply. There are two cables coming out from the outside box, but no further splitters or amplifiers going into the modem.

    You could see if the modem works better on a different cable outlet. I'm still seeing noise in one of the upstream channels so if that doesn't help a tech may be needed to troubleshoot further.
