wireless connection

I use HP Compaq business desktop DX6100. I was able to connect through my wireless internet CDMA USB device in linux-mint 9. But after i installed Ubuntu 10.10 maverik, it is not working, although device is working fine in my other Win7 machine. I have done all configuration right.
But still it is not working. please help.
