Generell ist ein Dist-Upgrade bei Debian Derivaten problematisch, hab ich mir sagen lassen. Diese Erfahrung hab zum Ersten mit Ubuntu 9.10 und meinem Dell-Laptop Vostro (1320) gemacht, das WLAN ging auf einmal einfach nicht mehr. Hier ein paar hilfreiche Forumthreads und Todo-snippets, um das WLAN wieder zum Laufen zu bringen.

1. WLAN Treiber installieren

Thread  9.1 Karmic Koala / DELL Inspiron 1525: WLAN driver/device not detected

Here’s how to get the Broadcom STA driver working. You will need to run these commands in a terminal.

1. sudo apt-get remove b43-fwcutter bcmwl-kernel-source ndisgtk ndiswrapper linux-backports-modules-karmic

Removes packages that could conflict with each other.

2. ls /etc/modprobe.d | grep blacklist

This lists the contents of the /etc/modprobe.d folder. Check the output of this command and make sure that there isn’t a folder called *b43.conf, *bcm43.conf, *ssb.conf, or *wl.conf. If there is, rename the file by typing: sudo mv thefile.conf newnameofthefile.conf.backup

3. sudo apt-get install bcmwl-kernel-source

This actually installs the Broadcom STA driver.

4. sudo cat /etc/modules

This lists the contents of the /etc/modules file. Check the output of the command and see if there is a line that says wl. If not, run echo „wl“ | sudo tee -a /etc/modules. That appends „wl“ to a new line at the end of the file.

5. Restart your computer and enjoy your wireless! By the way, I noticed that you said that you right-clicked the network icon –> you’re supposed to „regular“-click it.

2. NetworkManager fixen

Thread: 9.10 Karmic broke my wireless settings

Strangely, editing /etc/NetworkManager/nm-system-settings.conf to set (ifupdown) „managed=false“ to „managed=true“ fixed both the wired and wireless connections! Odd, but it’s working so I’m happy.

Bei mir hats geholfen, das WLAN funktioniert nun wieder. Ich hoffe euers auch.
