Internet keeps disconnecting

Way more info needed. Its like saying "my car doesn't run"

Tell us more. 

What modem?

Router? Firmware on router?

What device is having issues?

What exactly are the issues? Are you able to connect but it doesn't work, can't connect at all, all devices, one device, etc.

the more details you can give us the better as we're not in your location and don't know your setup, what you're doing, or whats failing. 

You can go to www.netgear.com/support/  and type in your model number for manuals, firmware, and troubleshooting.
