Did this get resolved? I recently purchased the sb8200 and I am having the same issue with the admin page.
Hi, there. The firmware page that is accessible at 192.168.100.1 is not dependent on your internet connection. It should permit you to access it regardless of whether or not you're connected to the internet. If the page fails you load, you might want to speak to Arris about it directly. I believe their support number would be 866-362-7747. I hope this helps.
Thank you for your response. It turns out the accessibility on my modem is absolutely dependant on the internet connection (as the orginal poster claimed).
The 192.168.100.1 page loads and works fine with the cable disconnected. It continues to work after the cable is connected until the last light on the modem goes solid. I have tested this several times.
It seems cox blames arris and arris blames cox. I have been in contact with Arris multiple times. Near as I can tell I am guessing both are right. I would wager that Arris had/has a software load with this issue and cox is using it as there approved version. Or perhaps my version hasn't updated yet.
My version is (in case it helps, looks to be from 2022): AC01.01.008_122722_8200.03.07.733.CT
Alright. Is there a firmware setting you are trying to change? If so, can you change it with the coax disconnected?
There does not seem to be a way to update the firmware as a user. It seems like the ISPs keep control of the version they allow.
I had a similar problem with my old modem (also from arris). The admin page working when I bough it. One day it stopped working seemly for a year or longer and then one day it was working again. I assumed firmware updates were the source of the changes.
This is why I was asking the OP if it was ever resolved on the SB8200.
