Can I connect my cable modem C6250 to the app Nighthawk?

Looks like the C6250 is still using the genie app.

I read it. But the app did see a router.

Another problem that router every time reloads and didn’t give IP for my 5 devices. And 2.4 antenna is switched off and reloaded every time too.

Is this a new device? 

Who's your isp? 

do any devices work on it?

It’s not new. I use it a 2 year.

For me, it’s like a conflict between two antennas and IPs.
