Disabling the DHCP server on a router is needed in the following two scenarios:

  • When starting CUJO as DHCP server.
    This option increases user experience and protection level.

  • When connecting CUJO in Bridge mode while having DHCP server running on the main router (which is connected to the bottom port of CUJO device).
    If you do not switch off the DHCP server on your router connected to the top port of your CUJO, this can lead to network instability and will prevent CUJO from intercepting communication between devices on that network.


To disable DHCP server on your router, follow these steps:

  1. Login to your router to change the DHCP mode and LAN IP.
    In your browser type in your router IP address (usually called gateway address)
    To locate this address refer to your device’s user manual.
    More information can also be found on HowToGeek.com or Google.com

  2. Add the credentials such as username and password.
    If you have not changed them you can try using the default credentials of your device.
    To find default credentials you may have to refer to your device’s user manual.

  3. Turn off DHCP server on router
    To find this field refer to your device’s user manual.

  4. Change LAN (Local Area Network) IP address to: 10.0.0.1
    (Usually, this field already holds a value starting 192.168.x.x)
    To find this field refer to your device’s user manual.

  5. Save changes

  6. Reboot your router if it does not reboot by itself


* DHCP server is used to assign IP addresses to the network devices
