I was told by comcast that my modem needed to br replaced. After I installed the replacement as per their request my internet speed went from 177mbps to 70mbps. I pay extra for the"Blast" faster speed, but not I don't even get what I'm paying for.
I check the Wi-Fi and an wired computer both the same. Nothing has changed except the replacement modem.
What is the make and model of the new device?
