unifi portal preventing access to modem customer admin portal

[andmatca78]

I have some unifi APs connected via ethernet through a router to my Rogers modem (HITRON CODA modem). I'm trying to access the modem's admin portal via 192.168.0.1, but it keeps taking me to the Unifi network config portal instead of to the modem admin portal. How can I access the modems admin portal?

@andmatca78 if the modem is running in Bridge mode, the correct IP address for the admin page is 192.168.100.1  You should be able to access that IP address thru the Unifi router.

If the modem is running in Gateway mode, then the correct IP address for the admin page is 192.168.0.1  However, if the Unifi admin page has the same IP address, then it makes sense that you keep ending up back at the Unifi's admin page.  You would have to connect a pc directly to the modem and use 192.168.0.1 to access the admin page. 

The IP address that you use depends on the operating mode of the modem, its default Gateway mode or Bridge mode. 

Are you running a business account?  Just wondering how you still have a Hitron modem.  CODA-4582 ??

Edit 1:  If you happen to have a business account, its highly possible that you're locked out of the user interface.  I don't know if the default mode for the Hitron modem for a business account is Gateway mode, where the modem can be used for wifi purposes, or if the default mode is Bridge mode, where the modem simply acts as a modem and the customer is expected to provide a follow on router to run the customer side network.  

For residential customers, when the Hitron modem was provided to those customers, there was an issue with modem access via IPv4.  When Rogers switched over to IPv6 modem control, internally, to access the routers, the customer IPv4 access was lost for a period of time.  That was a firmware quality control failure.  From what I remember, IPv4 access was eventually restored but it took while for that to happen.  So, the possibility exists that this has happened again, locking customers out of the modem via IPv4. 

If you knew that the modem was running in Gateway mode, you could run a trace to anywhere via IPv6.  For a windows desktop / laptop run:

tracert -6 www.google.com

The result of that trace would show the Unifi router as Hop #1 and the modem as Hop #2.  You should be able to access the modem's UI via the IPv6 address.  Copy the IPv6 address and paste that into the address bar of your web browser, which should take you to the modem's login page.

This won't work if the modem is running in Bridge mode, as the modem does not show up in a trace when its operating in Bridge mode.
