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?

Thank you.

What do you mean by "doesn't work"? Is the card not recognized? Are you unable to connect to a AP (what type of encryption)? – Benjamin Bannier Apr 14 '10 at 21:12
    
Any particular wireless card? – Ignacio Vazquez-Abrams Apr 14 '10 at 21:18
    
Is the wireless card enabled in BIOS? – mattiast Apr 15 '10 at 0:41

Have you installed the drivers for the card. I am going to guess there isn't any or if there is support its ver limited for a Linux driver provided by Intel. – Ramhound Oct 27 '11 at 13:59

If you still have problems, look for the specific card you are using with this command:

lspci 

And Google for the driver of your specific card. I didn't have any trouble finding mine.
