Wireless Card Help

[FoxySenpai]

Alright, here's the deal. I JUST switched my computer from Windows to Ubuntu 9.10 and I have a few problems. I tried it out before on friends' computers and it looked just fine to me, but as soon as I switched it became a nightmare. Now my computer won't even recognize that it has a wireless card. I'm using a Dell Latitude D610 and it comes with a Broadcom Gigabit Ethernet card (please don't ask me about more specifics, I don't know much more than that. It just has what the manufacturers put in it, besides Ubuntu).
So I try to go to my wireless settings and it won't even read that I can connect to one. I tried to put in all of the settings for the connection, and nothing happened still. So, my dilema is that I can't get my computer to even recognize that I have a wireless card. What do I do? I got no help or anything.

Broadcom wireless is frequently problematic. Here's a link to ubuntu forums for someone with Ubuntu 9.10 with a wireless problem that was solved.

[SOLVED] 9.10 Broadcom Wireless to Work - Ubuntu Forums

If that doesn't help, open a terminal from the Applications tab and enter the command:

sudo ifconfig -a - then post that output here.

One of the more useful things about a Linux LiveCD is that you can boot it up and have a test run just to see if everything works before installing.

Please post the output of

lspci -vnn

There are two possible drivers for broadcom wireless cards. The open source b43, and the proprietary Broadcom wl. They mostly work with different cards, with a little overlap.

The b43 driver is included but requires non-free firmware to work. The above link is for the wl driver.

The output of lspci will tell us which you need. If you look for the wireless in that output, the following cards use the wl driver

14e4:432b "Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller"
14e4:4329 "Broadcom Corporation BCM43XG"
14e4:4328 "Broadcom Corporation BCM4328 802.11a/b/g/n"
14e4:4315 "Broadcom Corporation BCM4312 802.11b/g"
14e4:4313 "Broadcom Corporation BCM4310 Ethernet Controller"
14e4:4312 "Broadcom Corporation BCM4312 802.11a/b/g"
14e4:4311 "Broadcom Corporation BCM4311 802.11b/g WLAN"
14e4:432d
14e4:432c
14e4:432a

Other cards use b43 + firmware. Firmware can be had by doing (assuming you have a wired connection)

sudo apt-get install b43-fwcutter

isn't the broadcom gigabit ethernet card for normal lan?
i've got a dell inspiron with the same card, but wireless is intel wireless pro.
also, the dell drivers page seems to suggest the same: Drivers & Downloads

could you post the output of the following command:

lshw -c network

or the output of the lspci command as reed9 suggested (but is probably longer).
