Today I upgraded to the Arris SB8200 modem and when I have the coax cable plugged into the modem I cannot access the web gui using the standard http://192.168.100.1/. Also I noticed that all my lights are green and none are blue for bonded channel. How long does it take for the channels to bond and why can I not access the gui when connected to the coax network?

Hi there! I can definitely take a look at your account and see what I can do to get things working properly. Please send me an email and include your full name and address. You can email me at cox.help@cox.com.
Is it a standalone modem? Cox does control all the settings and even firmware versions on user owned modems. And installing the perfered firmware version on a new modem can take a min after initial bonding is complete. I assume you either called and gave Cox the modem information or used that web tool.
And on most modems once they are connected to the provider, limited or no access to the modem firmware is the norm. You won't have almost any setup control even if you can access it. Or it won't carry over and be saved if it seems to let you do some config.
Cox cannot prevent you from accessing the GUI on the modem from 192.168.100.1/. if you cannot access that, remove the router and connect your computer direct to the modem, and reboot the modem. Then startup the computer, and try to access it. If you cannot then you have a bad modem.
I will just trust you. Way to much work to take the router out of the path to the modem VS the reward LOL. At least until sometime when three is a problem that needs me to try this for troubleshooting too or something similar.
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
It's the same with me I cannot view the diagnostic page when my pc is connected to my router but if I connect directly to the modem and reset my ip I can then log into the modem to see all the diag pages. Seems to me it's due to the ip address I am getting from cox with this new modem. Also also don't seem to get any bonded channels as all lights are only green and no blues. Speeds are good though.
