Quick guide from the manual
This document provides essential steps to set up and integrate the Cisco Business 143AC Mesh Extender into an existing Cisco Business Wireless Network. Before starting, ensure you have an active internet connection, a configured Cisco Business Master Access Point (140AC/145AC/240AC) with Mesh enabled, and a router acting as a DHCP server.
Preparing your product
Connect the provided power adapter to the mesh extender and plug it into a power source. The device will begin its initial boot-up process, during which the LED will cycle through red, amber, and green colors. This is normal behavior.

Configuration methods
You can configure the device using either the Cisco Business mobile app or a web browser:
- Cisco Business App: Download the app, connect to the Master AP's SSID, select the discovered Master, log in, and choose Add a device to follow the setup steps.
- Web UI: Connect to the Master AP's SSID, launch a web browser, and navigate to https://ciscobusiness.cisco. Log in with your Master AP credentials.
Network integration
To add the mesh extender to your network via the web interface:
- Navigate to Wireless Settings > WLAN Users > Local MAC Addresses.
- Click Add MAC Address and enter the MAC address found on the back of the device.
- Set the Type to Whitelist.
- Save the configuration by clicking the red disk icon in the UI header.
- The device will cycle through LED states while joining the network; this may take ten minutes or more. A solid or blinking green LED indicates a successful connection.
Note: If the Master AP was not set up with Mesh support, you must enable it under Wireless Settings > Mesh and apply the changes, which will trigger an AP reboot.
Support
For advanced configurations and detailed mounting instructions, refer to the Cisco Business Wireless Access Point Administration Guide available at cisco.com/go/cbw143ac.
