I'm a kiddo with ubuntu just tried it minutes ago ,how to use internet using my reliance netconnect data card it is not popping up or asking for installation. Without it i cannot connect to interent.I'm using windows 7 ultimate 32 bit version and this question is for ubuntu 12.10 desktop 32 bit version.
You need to install two software packages to make the internet connectivity work consistently without breaking. They are wvdial and gnome-ppp (The front-end tool to configure wvdial).
Once this is done click on Connect!!!
