As mentioned before as a suggestion in another post I changed my Ax11000 ip to 192.168.1.1 from 192.168.0.1 and now I can web into my Motorola MB8611 at 192.168.100.1 . I put this MB8611 on Spectrum and all is well as I can now see my modems signal levels as I could years ago when Charter/Spectrum was using Motorola cable modems. 

I'm not using the latest firmware as I had issues dropping connection as others have mentioned here but in all fairness my cable lines had to be replaced from the pedestal back to my basement for signal issues. Everything is running great so I have not tried the new firmware again. 

I also just realized my Norton vpn will block this connection to the MB8611 when enabled, so I just disable vpn for the few minutes I need to look at my signals.
