@Kevin_Z i already try this but this has many bug and feature like tr069 protocol, acs server settings was not there. Thats why bsnl technical team was refused to setup to this device. they need tr069 acs server to verify there settings. @tplink head technical team please update the fetures and stability this devise was very capable. 

  @iamsubha26 

ACS is there
reset the device once
and open this page:
http://192.168.1.1/superadmin
create a new password.
after logging in, head to administration and enable CWMP from the lists
logout and refresh
then it will switch to normal admin mode
create a new password again, and CWMP should be there

  @IfranAli ok. Thank you, now I have the CWMP option 
The router has some stability issues, like sometimes hangs and lags, and the BSNL MAC cloning speed was reduced. 
Really need an update @tplink_head please update

  @iamsubha26 wait patiently

they are looking into the issue and cooking an update soon.
