 - Once it is done then make sure to restart the modem router. With this your Nighthawk C7800 setup is finished.
 
How to Enable Router Mode instead of Modem Mode?
The C7800 works both as a modem and a router, but usually it starts with the modem mode. To change it to a router mode you need to follow some steps:
Step 1: Log In
- You have to visit the nighthawk login page again or just open the Netgear Nighthawk app.
 - Make sure to type the admin credentials you have created earlier.
 
Step 2: Open Operation Mode Settings
- In the main menu make sure to go to “Advanced” settings.
 - You have to search till the time you notice “Operation Mode.”
 
Step 3: Switch Modes
- You have to choose “Router Mode” rather than “Modem Mode.”
 - After that save the changes you made. The device will restart automatically.
 
Step 4: Reconnect Your Devices
- Once the reboot is done you have to reconnect your phone or PC to the wifi.
 - Now, the C7800 setup is working in a router mode, which eliminates the need for separate router. You will also have access to more features like parental controls, firewall and QoS.
 
Common Problems and Fixes
- Internet not working after setup: It usually means that your ISP has not activated the modem. Either go through their activation page or call support. Make sure to restart the unit after activation.
 - Login page not loading: If nighthawk login won’t open then you have to remove your browser cache or can try some other browser. The Netgear Nighthawk app often avoids this issue completely.
 - Mode change but not saved: You have to reset the modem router. This is done by pressings and holding the reset button for about 10 seconds, then does the Nighthawk C7800 setup again.
 - WiFi keeps dropping: This usually points toward the outdated firmware. Open the app, check for updates and install them.
