Upgraded to Jaunty 9.04 and My Wireless No Longer Works

[chiques]

Hello Everyone,
I had my system to auto update. It updated my kernel to:



chiques@chiques-laptop:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 9.04
Release: 9.04
Codename: jaunty
chiques@chiques-laptop:~$



ifconfig doesn't see my wireless card:



chiques@chiques-laptop:~$ ifconfig

But lshw -c network does (without a logical name though:confused:):

I've read that b43-fwcutter needs to be reinstalled and I tried that using the package installer. I selected "Mark for Reinstall" but that still did not work. I would appreciate any suggestions.

A problem which is making most of the troubleshooting tutorials useless is that the command:


lshw -C network

is expected to print a "logical name" as described in pre-requisite #4 of How To: Manual Network Configuration without the need for Network Manager (http://ubuntuforums.org/showthread.php?t=571188&highlight=troubleshoot+wireless) for my wireless card but it doesn't. There is a logical name for my ethernet connection which is working fine.


When I run this command I see:


root@chiques-laptop:/home/chiques# lshw -C network
*-network UNCLAIMED

All of these wireless problems began when I upgraded to Jaunty 9.04. :icon_frown::icon_frown:



Is it possible to remove and reinstall the driver for my wireless card? I have the following wireless card detected.


03:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

Hello ladies and gentlemen,

This issue has been resolved. Out of all of the suggested recommendations, none of them worked.

Here is the fix for my specific problem.


1. Power down the notebook

2. Turn off the wireless card (yes, switch it off)

2a. If you have a logic switch, power if off before you shut down.

3. Power up the notebook

4. Boot to the desktop (with the wireless card off)

5. Power on the wireless card through the physical switch. Wait a few seconds and you should see the indicator light on the notebook register as "on". You will then see the bar icon begin it's search for wireless networks and hard drive activity.

6. At this point the local wireless network will be detected and if already configured it will connect to it.


Thanks for everyone's input.

The thing with lshw -C network is that it shows what driver is installed on the card.

Take a look at this, it might answer your question.
