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?
What do you get for the upload speed ?
