If your are unsure of CradlePoint Series or Model number, please click here

This article was written based on firmware version 5.1.2.

*NOTE* This article pertains to the following routers on 5. firmware: IBR600, MBR1200B, MBR1400 and CBR400 on firmware version 4.3.2

Overview:

Introduced in firmware 3.4.0 for  Series 3 CradlePoint routers, the WiFi Bridge feature allows you to establish a wireless link between two routers, putting them both on the same IP network.  In this example, a WiFi Bridge is established between two CradlePoint Routers but, the configuration can be applied to a non-CradlePoint wireless router and a CradlePoint that is establishing the connection.

  5. Select the wireless network you wish to join From the Site Survey section, in this case “Router1_SSID”.  If you do not see any SSID’s please click the Refresh button.                                          User-added image
  6. Click the Import button.                                                                                                                    User-added image
  7. A Profile Editor window will appear, verify all the settings match that of the desired WiFi network, and enter the WiFi Security Password needed to connect to the network (in this case, the WPA Password).
  8. Click Submit.

  15. Change the last octet of the Router # 2 IP address so that it is not the same as Router 1.  In this example, we’ve changed the Router 2 IP address from 192.168.0.1 to 192.168.0.2.  It is required that the IP addresses for Router 1 and Router # 2 remain on the same network.  For example two routers with IP addresses of 10.0.0.1 and 10.0.0.25 both with 255.255.255.0 netmasks will work but, IP address of 10.0.0.1 and 10.0.1.25 with 255.255.255.0 netmasks will not. Additionally, the routing mode need to be changed from NAT(default) to Standard.User-added image
  16. Select the Interfaces tab.  Move the network interface with the prefix “WiFi Bridge” over from the “Available” list to the “Selected” list.                                                                                                      User-added image
  17. Disable the DHCP server by selecting the DHCP Server tab and unchecking DHCP Server.  This is required for WiFi Bridging.
  18. Click Submit to apply the settings.                                                                                                   User-added image

After the save is complete use 192.168.0.2 to access Router 2, since the Router 2 IP was changed.  Router 1 administration access will be available on its IP address which for this example is 192.168.0.1.

Log into the Router 2 administration pages using the new IP address.  Navigate back to  Network Settings > WiFi / Local Networks.  Notice in the Primary LAN data there is an Attached Interface called WiFi Bridge.  Verify that the WiFi Bridge is connected, along with the signal of the connection between the two routers.  Close your web browser at this time.

Now, test that your computer can successfully communicate with Router 1 by getting a new IP address assigned by Router 1.
