I am trying to connect to a wi-fi network which has a proxy server in place.

On my C6 it finds the network with full strength bars but fails to connect. I have entered in the proxy address and port  but i need to enter in my user name and password for authentication. 

I can not find where to enter my user name and password anywhere in the C6 options. Am I blind?

Could someone please point me in the right direction.

Thanks kindly.
