Re: Sharp Decline in Upload Speeds

I too have the SAME issue, I've got an Arris SB8200 with a Amplifi mesh, everything was great up until a week ago, about 5/11/20, then I went from 8-10Mbps to barely 2, Xfinity told me to talk to Arris, Arris said that the upstream voltage was suppose to be about 48, mine was 39, THAT was causing the drastically low upstream speeds.  The downstream speeds are varyng between 70 Mbps and 300Mbps.
