    Comcast just pushed the old firmware (V02.01.03) to my modem, replacing the broken V09.01.01! Fingers crossed that the problem is solved.

     

    800-COMCAST was totally useless for this problem.  I was told that Xfinity never changes the firmware (apparently they don't even have the capability to do so), that I should contact Netgear for support, etc.  Over 10 calls resulted in the same result. Two techs came on site, and both said that it was a modem problem, but would not/could not solve it because it was my modem. I was repeatedly told to rent an Xfinity modem.

     

    DSL Reports was the only access to knowledgeable support.  Although it was a slow interaction, they acknowledged the problem, investigated it, and said that a downgrade was forthcoming. Hopefully the company is rolling the downgrade out to everyone and not just those who find DSL Reports for help.
