Configure Enterprise Wi-Fi

Enabling Enterprise Wi-Fi allows a much more secure Wi-Fi access based on WPA/WPA2-Enterprise/802.1x protocol. This enables TLK radios to be deployed over Wi-Fi networks that require WPA-Enterprise-based access. A WPA-Enterprise network requires authentication by the RADIUS server, during connection with the Wi-Fi.

The authentication methods supported by TLK devices are:

  4. EAP-PWD

Certificate Management

EAP-TLS authentication, uses certificate based authentication. 

For this configuration of the Wi-Fi, a certificate management server is necessary which is  based on Simple Certificate Enrollment Protocol (SCEP) to handle Certificate Enrollment, Renewal and Rollover. The radio automatically renews the certificate before they expire. The configurations setup in SCEP server are used to configure the Enterprise Wi-Fi parameters in the portal.

For this type of authentication, it is necessary to perform the first time onboarding of the device on Enterprise WiFi in a secure network environment. Refer to

Configuration Details

To begin configuration, select the Device and choose Manage Wifi Networks option under Actions tab.

This leads to the “Wifi Networks” setting page, where the configuration for the new Wifi network is to be done. 

Following are the required configurations for Enterprise Wi-Fi:

Type – Select Enterprise

Enterprise Security Protocol – Select the type of authentication protocol 

Common Name – For EAP-TLS type, this refers to the name to be used for certificate issuance by SCEP Server. For other types enter the name associated with the Enterprise Wi-Fi account.

Password – For EAP-TLS type, this refers to the Challenge Password issued from the SCEP Server. For other types enter the password associated with the Enterprise Wi-Fi account.

SCEP Server URL – This is required for EAP-TLS type only. The URL for SCEP server should be entered here. For other types, just enter “none”. 

Root certificate URI – This is to specify a preferred folder name where the root certificate is located.
