eth%d: 5.100.82.38 driver failed with code 21 -> 0: dell-wifi: Wireless LAN Soft blocked: yes -> Wireless Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) not working on Dell Inspiron 6400 Model MM061 in Ubuntu 11.04

Asked by Cassy G on 2011-07-19

I just installed Ubuntu on my computer when it was done installing Broadcom STA wireless driver error occurred which says:

"Proprietary drivers do not have public source code that Ubuntu developers are free to modify. Security updates and corrections depend solely on the responsiveness of the manufacturer, Ubuntu cannot fix or improve these these drivers."

I don't know what to do. Please Help! What should I do?

My Computer is a Dell Inspiron E1505. And I installed Ubuntu to my harddrive.

Install them, it will make your hardware work.

From where should I install them?

Hi,

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

So the methods in Unity are:
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'Manufact|Product'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'icd|etwork'; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Step 4: Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a LiveCD session.

Regards,

Mark

First issue:

You have activated both the ndiswrapper driver and wl driver at the same
time. This should never be done... The 2 wireless drivers are in conflict with
each other...

Copy-paste the following command into the Terminal and then press
<ENTER>:

gksudo gedit /etc/modprobe.d/blacklist.conf

Using the gedit editor, ADD the following configuration line into the
file:

blacklist ndiswrapper

Using the gedit editor, SAVE the change to the
/etc/modprobe.d/blacklist.conf file.

Second issue:

I am pretty sure that your BCM4311 wireless adapter is experiencing the following Broadcom driver bug in Ubuntu 11.04:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/732677

I suggest installing bcmwl-kernel-source (5.60.48.36+bdcom-0ubuntu5) from maverick (Ubuntu 10.10) using gdebi

Solution is described here:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/732677/comments/23

Then reboot your PC and run the following commands to enable your wireless adapter:

rfkill unblock all
sudo rfkill unblock all

Then retest wireless using NetworkManager AFTER fixing the 2 issues above.

I solved my own problem by going on the website below (Alternate Solution 1 helped me). Hope this can help someone else.
