Introduction

With Qualcomm Wi-Fi Self-Optimizing Network (SON), installing Wi-Fi routers/home gateways, and adding devices, and range extenders is hassle free. It also detects and rectifies performance and interference issues on its own. The technology dynamically selects the best Wi-Fi link for each device based on application, band and context, giving each one the bandwidth it needs for optimal performance. More connected devices means more ways to compromise a Wi-Fi network. That's why Wi-FI SON offers a framework to build security mechanisms that are designed to prevent and quarantine potential threats and alert users of the issue.

Set-Up Wi-Fi SON (Central AP & Range Extender) using CNMS

Things to Prepare

Here are some things to prepare, for example.

  • Software: CNMS v1.6.0-beta.1.
  • AP Firmware v4.0.1_b171010
  • 3 x WPJ558 AP (1 as CAP and 2 as RE).
  • 1 x WLE600N5-18 (For CAP).
  • 2 x WLE900VX-7AA (For RE)

Notes

Before start configure Wi-Fi SON setting:

  • make sure the LAN setting for IPv4 address, gateway and DNS server(8.8.8.8) were setup as desired
  • make sure the WIFI SSID and WPA2 were setup on CAP before the Wi-Fi SON was enabled(If needed)
  • make sure firmware of the board is support Wi-Fi SON feature
  • make sure API version of the board is update-to-date in CNMS

Configuration Steps of Wi-Fi SON

1. Go to Client Access Point (AP) Tab, click ‘Wi-Fi SON’ tab.

2. Configure Basic Settings for RE-Placement and Auto-Configuration (repacd)

Configuring Central Access Point (CAP)

1. Change repacd setting accordingly as follows:

  • Enable RE Placement and Auto-Configuration
  • Network to extend : lan
  • Primary device purpose: Range Extender
  • Mode when connected to gateway: Central Access Point
  • Method of range extension: Wi-Fi Self-Organizing Network (SON)
  • Interoperable RE mode to use: Extender AP

2. Save and Apply

3. Check WiFi tab and you will see radio setting will change automatically, i.e. SSID change from 2 to 4 by created a station for each radio.

Configuring Range Extender (RE)

1. Make sure there is no WAN interface in the network setting.

2. Change repacd setting accordingly as follows:

  • Enable RE Placement and Auto-Configuration
  • Network to extend : lan
  • Primary device purpose: Range Extender
  • Mode when connected to gateway: Access Point
  • Method of range extension: Wi-Fi Self-Organizing Network (SON)
  • Interoperable RE mode to use: Extender AP

3. Save and Apply

4. Check WiFi tab and you will see radio setting will change automatically, i.e. SSID change to be the same as CAP.

Configuring Wi-Fi Protected Setup (WPS)

It will do automatic cloning of credential for both 2.4GHz and 5GHz with single button press simultaneously in both CAP and RE devices.

Repacd must be enabled, in order to execute WPS button.

Before execute WPS button, both CAP and RE would have different wifi setting; i.e. SSID.

Steps to execute WPS button

1. Go to Client Access Point (AP) Tab, click ‘Wi-Fi SON’ tab, you will see WPS button.

4. Wait for 2-3 minutes for the automatically cloning of credential completed. In WPS Auto-Configuration of CAP, its status will show ‘Device connected!’

5. Check WiFi tab and you will see radio setting will change automatically, i.e. SSID change to be the same as CAP even the credential.

Observations

1. CAP & RE1 & RE2 all are having the same credential for both 2.4GHz & 5GHz.
