hi,

thanks for reply.

I have already tested in image@2.4.0...it works perfectly but  want to do the same in image@3.1.1.

I have also tried in image@3.1.1, it works but whenever restart device ,  I am facing below problem.

1. when I type "ifconfig" it should display ppp0 but it automatically detects wwan0 and displays wwan0 and google ping doesn't work. 

to solve above problem ,  i have to follow below steps every time device restart.

1. add ppp settings in interfaces file.

2. remove check mark from cellular.

3. ifup modem.

then again type ifconfig it displays ppp0 and google ping works fine.

so please provide me solution for: whenever i restart device google ping should work without reconfigure.
