Long story short, I noticed some buffering issues when streaming netflix, I went and looked at my account page and saw that my modem is configured for Internet Performance instead of Internet Performance Pro
I have contacted both online support AND phone support, BOTH did the restart of the modem, check health, etc... Both said the modem has the correct bootfile, etc..
After all those attempts to reset my modem, I ran a speed test for them
35 MB Down, 5 MB up
same SPEEDS. Nothing changes, this is DIRECTLY connected to the modem and a cat 6 cable ( doesn't matter ). I ASKED them to re-roll the provision for the modem and got stupid responses like "It already has the correct bootfile", yadda yadda.
On your bill does it actually say Performance or Performance Pro? If it says Performance you will need to pay for an upgrade to Performance Pro. Also I would call Comcast again to just ask them what your internet package is named mainly and/or what it includes.
