Hi
I tried to install this router for my MTNL connection, but still i keep getting error - Internet down
possibly due wrong password/username

But i punched in same username/passwords as with MTNL router

Use wizard and select mtnl.

Username is either your phone number or your phone number with @a.

Password is your CA number. Verify entered credentials again.
