Can you post your signal levels from 192.168.100.1? Also, do you see anything in the logs like T3/T4 time-out errors?
I can't login to my cable modem. I can factory reset it, but when I login with the default username and password it brings me to a "change password" page. When I change the password, it returns an error that says "Device failed to update password."
My guess--and it's just a guess--is that Cox flashes the firmware via the coax when I first plugged it in, and did so in a way that prevents subsequent password changes. But without that, there's no way for me to login to the admin console.
Edit: That's interesting. Having multiple numeric characters apparently doesn't work. I figured out a combination of characters and one numeric character that does. Let me look through the logs...- WiderMouthOpen3 years agoEsteemed Contributor II
Don't post the logs without removing the modem MAC address from it.
Here are my logs:

I'm using a Motorola MB8600 now, and used to use an Arris (SB6183 as I recall) and have not had any challenges with getting to the admin functions on either one. I've read that if one connects to port 8080 a spectrum analyzer is available, but that does not work for me.
