CM1000v2 cannot access 192.168.100.1

How many times did you have to perform the factory reset?  I am having the same problem - performed a factory reset as specified in the note - no change in behavior.

    Kitsap - I don't think my Netgear modem has those configurations available to it as it's only a Modem (not a router).  When I get a minute do more testing on my environment, I'll see if there is a way to drop in a static route on the MODEM (but I don't think so). 

     

    That being said, I could always try to put the static route you mentioned on my ROUTER to see if that fixes the issue - certainly a good idea.  That being said, I was having the same URL failure problem when I hooked up my laptop directly to the modem (bypassing the router completely) so I doubt putting a static router on my ROUTER will fix it.... but, I will chase this down as anything is possible and I would like to get it working again.

    The static route for access to your modem is a configuration you apply to the router.

      Hoping someone may know why all of a sudden, I can't access the CM1000v2 modem diagnostics page: http://192.168.100.1 It boots up and seemingly resets its settings, reconnects, but still doesn't let me in.  I have no problem with internet access, but I cannot access the modem configuration page at 192.168.100.1.

       

      It won't load the login screen and only times out.

       

      I performed a factory reset (while unplugging COAX) - same behavior.

       

      I did another factory reset while is everything was plugged in - for a minute, I could get to the login screen, but when i plugged in my information (click login), it just refreshed the login screen again.
      Another minute later, back to timeout errors.

       

      To debug this. I've got my laptop (PC) connected to the modem directly (so there's no wifi/router concerns) and nothing else is connected to the modem.

      When I try to access 192.168.100.1, the web page just times out without giving me a login prompt. I've rebooted the modem and laptop and tried a factory reset and nothing has made any difference.

      What I have noticed is that when I first reboot the modem, my machine gets 192.168.100.10 as its IP address (but 192.168.100.1 doesn't respond at this time). Once the modem is fully booted and connected, my IP address flips to 73.223.xxx.xxx (Comcast public IP space).

       

      Other things I've tried:

      -Looking for 192.168.0.1, 192.168.1.1, 192.168.100.10 but none of those IPs respond either.
      -Tried a different (Windows) laptop just in case there was something weird in the networking on my first laptop - same behavior.
      -Tried reconnecting to my home network - same behavior (Network path is PC-->Asus RT-AC88U Mesh --> Netgear CM1000v2 --> Comcast Coax)
      -Tried reconnecting to my home network via iPhone and iPad - same behavior (Network path is Apple device-->Asus RT-AC88U Mesh --> Netgear CM1000v2 --> Comcast Coax)

       

      NOTE - this issue only started after a RECENT comcast outage in my area that has since been resolved. Prior to this outage, everything worked as expected. As mentioned, I can get to the internet, so it's not the end of the world, but I simply cannot login to the modem to check status.

       

      Thanks in advance!

        When I had this problem (my post from a couple years ago), I recall only needing to reset it once with the coax disconnected. I can't check right now, but I was still able to access the settings page a few months ago.
