Can't enable wireless card

Can you please give the output of:

sudo lshw -C network

Thanks

I am going to start typing the output, but is there anything in particular you are looking for? I can't cut and paste it.

We need the product line.

product: bcm4318 [Airforce One 54g] 802.11g wireless LAN controller
vendor: Broadcom Corporation

https://wiki.ubuntu.com/WifiDocs/Driver/Broadcom43xx

Get a wired connection and it will install itself.

Thanks!

Hopefully, I won't get in trouble for tapping into the wired connection I ended up using.

Unfortunately this didn't do it, still can't activate the wireless card.

Something else I just noticed, the enable wireless button in the NetworkManager right click menu is no longer there.

How about using Broadcom's proprietary driver. See if you could find the "Hardware Drivers" in the Administration menu and enable any driver which coincides with bcm4318.

*I'm using a Lenovo laptop with Broadcom Corporation BCM4312 802.11b/g (rev 01) as my wireless card, enabling the proprietary driver (Broadcom STA wireless driver) works like a charm*

HTH.

Thanks, the only driver listed is the one I just downloaded, where can I download the Broadcom STA wireless driver?

i am also facing the same prblm ,but i have a Dell vostro 1510,
i typed the cmnd sudo lshw | more , but was unable to locate my wireless driver
. pls tell me a step wise soln for this as i am a beginner , so have a less idea about ubuntu;
Thanks

My card says disabled, what's the command to enable it?

thenubsauce please give the output of:

sudo iwlist scan

The device seems to have a driver (ath9k) and is giving you the device wlan0. Lets see if it scans to find access points (APs)

If it does't then use this guide but replace Jaunty to your release name if you do not se Jaunty:

looks like you need the b roadcom firmware cutter, if you hook up the wired connection to the internet you will simply be offered the driver and it will automatically be installed for you (easier)
