Having to reprovision my modem every day
I've been having a systemic issue for the past 9 days where I get an invalid security certificate when trying to access most websites. Sometimes I can get to the "walled garden" when it says the certificate is only valid for register.be.xfinity.com. If I register my modem, the problem is resolved until the next day. Most days I have to call Comcast tech support and have someone reprovision my modem, but again the problem comes back the next day. All tech support can tell me is I seem to be loosing my bootloader file every day.
Here's what I've tried:
1) Bought new cable modem (went from DOCSIS 2.0 to DOCSIS 3.0)
2) Upgraded services from an older grandfathered plan to the performance starter
3) Factory reset the cable modem (pin hole button on back of panel)
4) Try to use the My Account app to reset modem (app gets an error "can't access account details" only when I have this security certificate problem.
Does anyone else have a clue why this might be happening? I found some related threads where other people have this issue as well, but they haven't found a resolution. Here's a screen shot of the error:
