Nighthawk C7500 stopped 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. Now, I can't even change SSID name, nor my passphrase. Web UI simply doesn't do anything and does not responding when I click "Apply". Also it prompts me for user name and password every time I click on any link within Routerlogin.net UI. The firmware version is V1.01.32. Is anyone else experienced this?

So disconnect the ISP Coax cable and the power adapter from the modem for 1 minute. 

Reconnect the power adapter to the modem only. 

Power ON the modem and let it come to ready.

 

Press the reset button for 10 seconds then release. 

Connect 1 wired PC to the modem. 

Walk thru the modems setup wizard.

After completing the wizard, check the Basic tab/Wireless settings page. Does 2.4Ghz appear here or seem accessible or indicate any problems?

"Reconnect the power adapter to the modem only." - this unit is modem + router combo

Yes. I know. The statement was in reference to only connecting the power to the modem only and don't connect the ISP coax line.
