C7500 UI not responding and broadcasting 2.4G
A few days ago I've noticed that some of my devices running on 2.4G Wifi got disconnected. I routerlogin.net to my router and can't find 2.4G setup anymore. I did factyory reset, which didn't helped. ...
it's okay, I'll figure it out. everything works on my ISP part except for the router login. what I'm noticing is that it's trying to redirect the page but couldn't open it so it leaves the settings area blank.
Any Criticals, Errors or Warnings seen in the event logs are indications of a signal issues on the ISP coax line up to the modem. Any of these seen in the event logs needs to be reviewed by the ISP and resolved.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Thank you for the steps. After all of the troubleshooting that I have done already, the issue is not on the ISP end because everything else works just fine, just can't configure anthing in the admin console. However, after all of the settings I was able to get to, they made no effect to my changes but ONE THING....I was surprisely ABLE to disabled NAT Mode so I could use the modem/router as just a modem alone connecting a new router to it without an IP conflict. I THINK...the issue is with the router part itself, again not an ISP and I may know how to fix the combo (use the reset inside the board). My conclusion is that router part may have gotten hung up and needed a master reset if the reset button doesn't work from the outside, you go inside the board to force it (push button).
I will try this and let you know but really dont want to mess with it since my internet is working as intended and configured the new router already.
Yes modem mode would work for you as well for a external wifi router.
However again, Cable Connections and Event logs are still important as they report issues and such from the modem side while in modem mode. Be sure the ISP reviews them and resolves any issues seen there.
Good Luck and enjoy.
