Modem upgrade decreased download speed
We have 100Mbps down/ 5Mbps up plan. I recently upgraded our cable modem from a Ubee DDM3513 (now unsupported) to an Aris SB8200 and our download speed has decreased from 110Mbps to 30Mbps. I have tried reactivating the new modem multiple times but the issue persists.
I suspect that the modem is being misconfigured during the provisioning process. How can I get someone to look into this?
I've attached the modem status page along with a spectrum analyzer plot.
