How to configure WLAN in Bridge mode with the external DHCP server?

Summary:

This document explains about the requirement and configuration required while configuring the cnPilot AP in Bridge mode with the external DHCP server.

Cause:

If APs and Clients are on the same VLAN or separate DHCP server is in the network to provide IPs to the clients.

Topology:

DHCP server >> Router >> POE/Switch >> CnPilot E-series device.

Note: I have considered VLAN 1 as an example as my DHCP server is configured with IP pool in VLAN 1. You can use any VLAN as per your Network requirement.

Solution:

Please follow the below steps to configure the AP:

Step 1: Log into the GUI of the AP using the IP address and Enter the Username and Password.

Step 2: To create VLAN Interface:

Click on Configuration>>Network>> VLAN>>Add new L3 interface and select a VLAN ID as shown in the figure below:

Select the IP address as DHCP as shown in the figure below:

Step 3: Click on Configuration >>WLAN >>Add LAN

Create a Wireless LAN tab and select the WLAN ID (Any number) as shown below:

Step 4: Configure >> WLAN>>Basic

  • Enable¬†the radio
  • Mesh¬†is off by default
  • SSID: Choose the SSID that will be broadcast for this WLAN.
  • VLAN: You can assign a VLAN to this WLAN. By default, the VLAN is set to 1 and is untagged. However, you can select any valid VLAN ID as configured Under¬†Network >>VLAN
  • There are three options available for¬†Security:
  1. Open should be selected to give access to clients to connect with SSID without using any password.
  1. WPA2 Pre-shared Keys: - We need to enter a password in the Passphrase field to provide security.
  2. WPA2 Enterprise: - To use a Radius server for authentication.
  • Configure¬†Max Client as¬†per your requirement and Click on¬†Save¬†to save all the above configuration.
  • Leave rest of the configuration as default.

Please find the below screenshot for your reference:

Results: In this case, the client will connect to SSID cnPilot and gets IP from the DHCP server which is in your Network in VLAN1.

The dashboard will provide us the information of the clients once they connect with the SSID as shown in the figure below:

Note: Ensure that AP is on the latest version. You can check or download the latest version for cnPilot E-series devices from below Links:
