I have a Motorola modem that I purchased, not supplied by Cox and I can no longer reach the Modem Information Page 192.168.100.1 I used to be able to access it to check signal levels, etc., but not anymore. Is there a reason for them to be blocking this on customer owned equipment?
Have you tried connecting direct to the modem and trying that IP? Some routers block the 192.168.100.x range.
Also, what model modem do you have?
What happens when you enter 192.168.100.1 into your browser: unreachable, timeout, certificate, etc?
It says connection times out which it has never done before. I tried pinging it and that comes back as unreachable too, which is interesting.... It's a SB6121 so I know the info page is at 192.168.100.1 Rebooting router and modem still didn't fix it either... I even tried accessing it from my phone (while connected to my WiFi) and still get the same problem.
I had the same problem on 2 devices: unreachable, timeouts and no ping. I too had just replaced the modem but the new modem wouldn't issue a new certificate...or if there was ever a certificate with the previous modem.
I wish I knew what I specifically did...or did anything at all...but the browser eventually and finally displayed the Add the Certificate page.
In no particular order, things I did...
- Reset Modem from Cox Page - Disabled Firewalls - Forced Certificate Update - Rebuilt TCP/IP Stack - Updated NIC Drivers (Although I Knew No Updates were Available) - Direct Wire
Direct Wire works so I think it is narrowed down to the router not being able to find a route to it. The router is 192.168.1.1 and the modem is 192.168.100.1 so it's in a different network.
