Airtel
Unable to get support from 121

I have airtel broadband connection and now I have lost the link where I can add remove wifi child nodes. This was provided to me when the modem was set up by technician. When I called 121 they said no such link is available and they cannot help.

How come is this possible, when I was using a link something like mywifi..com

Now the modem technician from airtel is not picking call.

Please provide solution.
