We will show you how to turn off the DHCP Server so CUJO can work in DHCP mode.

You will need to change the DHCP Settings as set out below if you wish to connect your router to CUJO in "DHCP mode".

 

Connect CUJO:

At this point your CUJO has to be connected using just bottom CUJO port:

 


Activate DHCP mode using CUJO app:

Before turning off the DHCP server on your Router you have to activate it on CUJO (DHCP server will not be started until you reboot CUJO).

If you see the manual setup instructions page on the CUJO app, this means the DHCP server was activated on CUJO.


 

Disable DHCP on your Router:

Once you have connected CUJO and activated the DHCP mode on it, you can disable DHCP on your Router;

1) Login to your router.

Link: http://192.168.1.254

Device code: (located on your router)


2) Make an IP reservation for the CUJO

Depending on the model of your router you may see one of these interfaces:

a) Navigate to “Home Network” -> “IP Allocation”

Find a CUJO on the list and press button "Allocate"

Choose the same IP from the list (in our example 192.168.1.138) and push "Save"

- - - - - - - - - - - - - - - - - - - - OR - - - - - - - - - - - - - - - - - - - -


b) Navigate to “Settings” -> "LAN" -> “IP Address Allocation”

Find a CUJO on the list and choose "Private Fixed" address same as "Current Address" (in our example "Private Fixed: 192.168.1.138")

To save settings push "Save"


3) Change the DHCP range of the router to single CUJO IP

Depending on the model of your router you may see one of these interfaces:


a) Navigate to "Home Network" -> "Subnets & DHCP"

Change "DHCPv4 Start Address" and "DHCPv4 End Address" to have same value of CUJO's IP address (in our example 192.168.1.138)

To save changes press "Save"


- - - - - - - - - - - - - - - - - - - - OR - - - - - - - - - - - - - - - - - - - -


b) Navigate to “Settings” -> "LAN" -> “DHCP”

Select "Configure manually"

Enter "Router Address": 192.168.1.1

Enter "Subnet mask": 255.255.255.0

Enter "First DHCP Address": CUJO's IP (in our example 192.168.1.138)

Enter "Last DHCP Address": CUJO's IP (in our example 192.168.1.138)

To save settings push "Save"


4) Reboot CUJO (unplug power from CUJO and plug it back) and router


Once both devices reboot, CUJO will start protecting all your network devices connected to AT&T router.
