MB8600 - Not able to login to modem on the network

QUESTION:  "I am unable to access this modem to change admin name and password.  Using the IP address associated with the modem (  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)

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 - it should be in most cases

  • If you want port forwarding to work, you need to login to your modem and find the "DMZ" setting (related to port forwarding). Put the WAN address of your router into this setting, then you can manage port forwards from your router.
