QUESTION: "I am unable to access this modem to change admin name and password.  Using the IP address associated with the modem (192.168.100.1)  I cannot get to the login page."
(Customer is using a router attached to the MB8600)

ANSWER: There are several fixes if you are not able to access your modem on your network (especially if you have different subnets ):

FIRST solution :

  • Always power cycle your modem and router first, and then try logging into your modem again

  • If you have a router between your computer and modem, remove it and directly connect the computer to the modem via an Ethernet cable

  • Plug directly into one of the hidden ports of the modem (remove the sticker covering the extra LAN ports)
  • If you're using a VPN or antivirus, try disabling it, then attempt to log in again.

ROUTING solutions :

  • Your router may be the issue.  Changing the DHCP settings to have IP addresses in the 192.168.1.xxx range instead of the 192.168.0.xxx range may fix it

  • You may need to assign your computer a static IP before you are able to login to the modem

  • Check that the router isn't setup as 255.255.0.0 - it should be 255.255.255.0 in most cases
