I have installed ubuntu 9.10 on my laptop. It has a 802.11n wireless card. When I boot up to ubuntu, the wireless does not work. And if I connect to a wire network within ubuntu, it works.
Ubuntu can't detect any of the Wifi network in my home (other laptop can). And I click 'Enable Wireless' in the notification area, it said 'Device not found' for the Wireless Network.
The card is 'Intel Wireless-N Card with Bluetooth'
Can you please tell me how can I setup my wireless card in ubuntu 9.10?
