How do I set up the CradlePoint AER 2100?

Beverly McRae

Quick Start

Basic Setup

1. Insert an activated SIM.

A wireless broadband data plan must be added to your CradlePoint AER 2100. Wireless broadband data plans are available from wireless carriers such as Verizon, AT&T, Sprint, EE, and Vodafone. The SIM must be provisioned with the carrier. Contact your carrier for details about selecting a data plan and about the process for provisioning your SIM.

Once you have an activated SIM, insert it into the integrated modem. Insert the SIM card into the slot marked SIM 1 (use the other slot, SIM 2, for a secondary/backup SIM).


Be sure to insert the card with the notch-end first and the gold contacts facing down – it will click into place.


2. Attach the integrated modem.

Follow these steps to attach the integrated modem:

1) Remove the left side panel cover from the router. Use a Phillips screwdriver to remove the screws, and use the Multipurpose Retaining Tool (included in the router package) to remove the cover.


2) Slide the modem into the side of the router. The protruding section of the green board fits into the groove.


3) Reattach the panel cover and screw it back on. (When necessary, remove the cover and modem using the Multipurpose Retaining Tool.)

3. Attach the WiFi and modem antennas.

Attach the three WiFi antennas (included) and two modem antennas to the connectors. Antennas are jointed, which enables you to position them for optimal signal. To attach, hold the antenna straight and twist the base of the antenna to connect, folding the joint if needed.

Examples of suggested antenna orientations:

Desk Mount


Wall Mount


Care should be taken to ensure that the router antennas are not near metal or other RF reflective surfaces.

4. Connect the power source.

Plug the provided power supply (12V DC wall adapter) into an electrical outlet. Then connect the power supply to the router.


Ensure power is switched on:

  • O = OFF
  • I = ON

When you set the power switch to the ON ( I ) position, watch for the power LED to illuminate.

If you would like to secure the power supply cord, attach the Multipurpose Retaining Tool as shown below. Secure with included screws.


5. Connect to a computer or other network equipment.

Connect wirelessly to the WiFi broadcast or with an Ethernet cable connected to your computer and then plugged into one of the Ethernet LAN ports (numbered 1–4).

The default WiFi network name broadcast is “2100-xxx”, where “xxx” is the last three characters of your router’s MAC address (this is the SSID on the product label). To connect to the WiFi, you will need to input the DEFAULT PASSWORD when prompted. The DEFAULT PASSWORD is provided on the product label found on the bottom of your router.

NOTE: The product label below is an example only: your DEFAULT PASSWORD and SSID will be unique.


Accessing the Administration Pages

Once you are connected, open the CradlePoint AER 2100’s GUI-based administration pages to make configuration changes to your router.

  1. Open a browser window and type “cp/” or “” in the address bar. Press ENTER/RETURN.
  2. When prompted for your password, type the eight character DEFAULT PASSWORD found on the product label.


It’s possible – and more efficient – to do all your configuration changes through CradlePoint Enterprise Cloud Manager (ECM) without logging into the local administration pages. Set up a group of routers and set the configuration for all of them at once. See below for more information about ECM.

First Time Setup Wizard

When you log in for the first time, you will be automatically directed to the FIRST TIME SETUP WIZARD, which will walk you through the steps to customize your CradlePoint AER 2100. You have the ability to configure any of the following:

  • Administrator Password
  • Time Zone
  • WiFi Network Name
  • Security Mode
  • Access Point Name (APN) for SIM-based modems
  • Modem Authentication
  • Failure Check

If you are currently using the router’s WiFi network, you will need to reconnect your devices to the network using the newly established wireless network name and password.

NOTE: To return to the First Time Setup Wizard after your initial login, select GETTING STARTED on the top navigation bar and FIRST TIME SETUP in the dropdown menu.
