Arris S33v2 cable modem disconnecting everyday
I've tried calling 1-800-Xfinity and talking to AI assistant, then finally talking to a person, who told me to replace the ethernet cord between my cable modem and my router. I did this, but it did not help. Now I've found the xfinity forums and I'm hoping technical support still exists at this company. After briefly reading some other posts on the forum, I logged into my modem's web interface and below is the error log from the cable modem.
What should I try next? Thanks in advance.
