ArchivesBCM4328 Wireless Card and WEP in Ubuntu 7.10
November 4th, 2007When I installed Ubuntu 7.10 "Gutsy Gibbon" on my Dell Latitude D830, the wireless did not work out of the box. Using ndiswrapper, I was able to get it working (Ubuntu 7.10 "Gutsy Gibbon" on a Dell Lattitude D830) and icon in my notification area at the top-right corner of my screen (nm-applet 0.6.5) would show a list of available WiFi connections and their signal strength.
Note: My BCM4328 wireless card is identified through the 'lspci' command as:
Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03)
I could then select my network (which is an open network) and connect without any problems. However, when I tried to connect to a WEP key protected network later at a hotel, it would not connect. Upon further reading, this seems to be a common problem. Although it's talked into the ground throughout the web, I just need to connect to WEP networks once in a while--at coffee shops and hotels and the like.
When I go to a cafe or hotel and need to get my Ubuntu Gutsy Gibbon and BCM4328 Wireless card working on WEP networks, these are the steps I take. (If you don't already have ndiswrapper setup for your BCM4328 WiFi card, read Ubuntu 7.10 "Gutsy Gibbon" on a Dell Lattitude D830).
Note: You could spend some time and set up a better solution, however, it's very rare that I need to connect to a WEP network and I like using the nm-applet with roaming mode. This was the first thing I figured out that worked for me and I don't intend to spend any more time on the topic. Just thought I would share with other users. Feel free to post a comment if I'm doing something ridiculous.
- Left-click the Wireless icon in the notification area (nm-applet) and select 'Manual Configuration...' from the menu to open the 'Network Settings' dialog.
- Select 'Wireless connection' and click the 'Properties' button.
- Under the properties for wlan0, un-check the 'Enable roaming mode' box. I put the information I'll be using only so that the 'OK' button is enabled. However, the connection still will not be working at this point, but, the roaming mode will be turned off.
- Back in the 'Network Properties' dialog, I un-check 'Wireless connection' and click 'Close'
- Finally, I open a terminal and issue these commands:
sudo ifdown wlan0
sudo ifconfig wlan0 essid TheNetworkSSID key abcabc1234
sudo ifup wlan0
Where "TheNetworkSSID" is the network you want to connect to and "abcabc1234" is the WEP key. Typing 'ifconfig' again with no options will confirm that the network connection to "TheNetworkSSID" was established (or show nothing for the essid if it did not take)

Hi Micah
I have the same environment as you have used in your article:
dell d830, broadcom bcm4328 rev 03, and ubuntu 7.10.
I managed to get my ndiswrapper loaded, my nm-applet shows networks. I also managed to connect to unprotected networks, got an IP from the dhcp server and could ping the gateway.
I did not manage to get my protected WPA network running though. Did you tryout WPA too, or only WEP?
When I use the functionality of the nm-applet it suggests me to use WPA-personal, I enter my ESSID and password, but it keeps returning on the password, I guess this is some kind of bug with the password manager.
Your trick above would just shutoff this nm-auto-functionality and set details by hand?
Are your commands above correct? Should the ifconfig not be iwconfig?
I did not get it running, my card did not get an ip.
Is there any issue with WPA? Do you need to take care of something else?
Regards, Jan Kester.

I did not try WPA actually, and I do recall (though this was quite a while back) that WPA was tricky. I had to do it by hand, but that was a different card at a different time.

Hello,
I had the same issue on my HP DV6500z (uses the same Broadcom chipset). I highly recommend using the great little utility called "wifi-radar" (you can find it in the standard repositories). Set the nm-applet to "manual configuration" and then use wifi-radar to manage your connection. Works great for me whether at home (WPA), or friend's place (WEP) or the local coffee shop (no encryption).
Hope this helps,
Shankar

Micah,
I have installed the wrapper and driver as you have outlined. Why don't I have the wireless icon in my top system tray?
Thanks,
Mike

I was able to get BCM4328 working without the ndiswrapper on my HP TX1000. It seems like the Broadcom 802.11 STA Linux drivers also works with BCM4328. Here is the link: http://www2.zdo.com/archives/33-Broadcom-BCM4328-and-wpa_supplicant-under-Linux-2.6..html
