I have bought an Asus wireless LAN PC Card WL-100GE model, and I am using lubuntu on my system. While I have no cable connection, currently I cannot access the internet and update my laptop.

Device: Broad Range Wireless Card Bus Adaptor - Asus - WL-100GE

I searched the web and couldn't find any adequate driver for it. Is there any solution for it?

My sudo lshw -C network output is:
