Hi, I have a CM1200 modem with spectrum, My service is 400mbps/25mbps I normally get the full Download and barely get 17mbps down, yesterday I started to have intermittent service, the modem goes off line and has to reconnect, I called for service and the man on the phone is blaming the modem. The logs on the modem are as follows.
I just factory reset the modem per the Spectrum tech on the phone.

I dont think I have a bad modem, however, I am looking to maybe rent theirs for a month or two just to make sure.
Anyone has any suggestions??
