Overview

  • Captive portal is part of onboarding process which is presented to user once device is activated.
  • It allows user to configure his/her WiFi credentials to be personalized which user can remember. It is presented to user if user does factory reset too.
  • It is presented to user if user does factory reset too.

  • On fresh boot-up and factory-reset, Captive Portal prompts to change the default ssid name and password for browsing on connected client’s through Gateway network

  • On fresh boot-up and factory-reset,, anything user tries in browser will redirect to local captive portal

Trouble Shooting

  • During any captive portal issues, verify the below commands .

syscfg get redirection_flag

To get value of redirection_flag (true/false)

root@RaspberryPi-Gateway:~# syscfg get redirection_flag
true

          

 syscfg get HTTPS_Server_IP

To get HTTPS_Server_IP to which it is connected.

root@RaspberryPi-Gateway:~# syscfg get HTTPS_Server_IP
10.0.0.1

 

 syscfg get PartnerID

To get partern id of syndication partners

root@RaspberryPi-Gateway:~# syscfg get PartnerID
RDKM
