[ubuntu] Wireless Internet Connection

view story

http://ubuntuforums.org – Dear friends, I have recently installed Ubuntu 13.04 on my Asus K53 Laptop. However I was unable to install my internet driver. I am from India and using Reliance Netconnect. The install.sh script is showing error "Can not continue without qt3 runtime library". I am unable to install the same without internet. In this regard if you could point to me how I can download those packages alongwith dependencies offline (if at all possible) and install them manually, I'd be very much grateful, otherwise I will have to say goodbye to using Linux on my laptop. Also if I use KDE Linux distro (Hardware)
