Recently upgrade my Dell Inspiron laptop into ubuntu 10.10 versions, where as I am having the second partition on the hard drive, where I installed windows XP service pack 1. The machine I used basically for the internet access. After upgrade the machine along with that I also insert a new wireless card. The problem is after insert the new wireless card; my machine is not recognizing the wireless card. The problem starts while I access the internet in my machine is it starts form slow connectivity. I am using the Rosewill RNX-G300E IEEE 802.11b/g PCI Wireless Card, the Network interface card is not working fine but this one only not recognize the wireless card. How to resolve the issue, any suggestion on this?
