Configure a capable Cradlepoint as a Wired and Wireless access point

Products Supported: AER2100, MBR1400v2, MBR1400v1, MBR1200B, MBR95, CTR35, CBR4x0, IBR6x0. Click here to identify your router.

Firmware Version: 5.3.0 - for information on upgrading firmware, click here. Please note that for the CBR4x0, MBR95, and CTR35 routers, there will be no further firmware updates, so the process defined below may be different for these routers.

Firmware version 6.0 has been released and introduces a vastly improved GUI for all current Series 3 routers.  Cradlepoint has created new Knowledge Base articles with updated screen shots and instructions for the new GUI layout.  As a result, this article has received its final update.  To view the version of this Knowledge Base article for Firmware 6.0 and Later please click here.

Summary

Series 3 Cradlepoint devices normally operate as a NAT router, allowing computers connected to the LAN to use the Internet connection provided by the WAN interface. As a NAT router, the Cradlepoint is responsible for providing DHCP and local gateway access to connected clients.

If your existing network already has a DHCP server and local gateway configured, it is possible to reconfigure the Cradlepoint to act as a wired LAN client to that router. This turns the Cradlepoint into a wired switch/wireless access point for that existing DHCP server and local gateway. Set up this way, any wired or wireless computer connected to the Cradlepoint will get an IP address from the existing DHCP server and route traffic through its local gateway.


Configuration

Configuration Difficulty: Beginner

These examples will show you how to reconfigure a Series 3 Cradlepoint router to be used as a wired switch and wireless gateway to connect to another "Primary Router" DHCP server and local gateway in your network.

For example, assume there is already an existing wired Primary Router using local IP address 192.168.1.1 with subnet mask 255.255.255.0. This is the router that is providing DHCP services and providing local gateway access. The Cradlepoint will be configured as a LAN client for the Primary Router.

To begin, first make sure that the Cradlepoint is not connected to the other router.

  • Step 1: Log into the router's Setup Page. For help with logging in please click here.
  • Step 2: Click on Network Settings and click WiFi / Local Networks from the drop-down menu.

  • Step 3: Scroll down to Local Network Interfaces and select the VLAN Interfaces tab.

  • Step 5: Select port 0 and remove it from the wan.

  • Step 7: In the VLAN editor for the lan, click the Add button.

  • Step 8: In the Port Editor, select Port 0 and select untagged, then submit the settings.

  • Step 9: Place a check mark next to Primary LAN and click Edit.

  • Step 10: Select the IPv4 Settings tab.
  • Step 11: Set the IP Address to 192.168.1.2 and the Routing Mode to Standard.
    • Note: This address is for this example only. Your network may have a different address range. The Cradlepoint's IP address should be on the same network as your primary router.

  • Step 12: Select the IPv4 DHCP tab.
  • Step 13: Remove the checkmark next to DHCP Server.

  • Step 14: Attach an Ethernet Cable from a LAN port on your Primary Router into any of the Cradlepoint's Ethernet ports.
    • Note: We suggest using the Cradlepoints WAN port for this connection as it retains a logical port usage to easily determine which cables are connected to which devices.
  • Step 15: You may need to refresh your computer's IP address (or else reboot the computer or Cradlepoint) in order to get a new IP from the Primary Router.

After making this change, the Cradlepoint will no longer be performing any routing functionality, but instead will act as a wired switch and wireless access point to extend your existing network. All DHCP, gateway, and routing functionality will be handled by the Primary Router.

Any computers wired or wirelessly connected into the Cradlepoint will receive IP addresses from the Primary Router (beginning with 192.168.1.X in our example). Any computer attached to that network should also be able to access the Cradlepoint from the LAN IP address you specified (192.168.1.2 in our example).

Note: It may be useful to change the Cradlepoint's wireless SSID and password to match the same credentials as your other router uses. This would allow nearby computers with the Primary Network's wireless credentials to be able to connect to whichever network has a stronger signal.

To undo this configuration you can either follow the directions in reverse order, or you can perform a factory reset of the device.
