Hi,

Please first connect your network card 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: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website 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 restart. 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 'ound|irmware|eth|ath|wl|ipw|rtl|rt2|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; sudo /etc/init.d/networking restart

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 specify the exact model and make of your PC (if known).

Regards,

Mark

Revision history for this message
Mark Rijckenberg (markrijckenberg) said : 		#3

There are several issues with your Ubuntu install:

You have mixed feisty, gutsy and lucid repository lines in your /etc/apt/sources.list file. This should NEVER be done, as it can and WILL damage your Ubuntu install. The sources.list file should only contain references to lucid, if you have upgraded to Ubuntu 10.04

The second issue is this error output that you sent us:

"iwlagn 0000:04:00.0: iwlwifi-6050-1.ucode firmware file req failed: -2"

This means that your wireless card is not working yet, because it cannot load the missing firmware files.

Please try this solution for the firmware issue:

Revision history for this message
Mark Rijckenberg (markrijckenberg) said : 		#5

If installing the linux-backports-modules-2.6.32 package from the lucid-proposed repository does not fix this wireless issue, then the only remaining option is to install the Alpha 3 release of Maverick Meerkat (Ubuntu 10.10 alpha 3) from a LiveCD session.

Keep in mind that Maverick is still in alpha phase and NOT ready for production machines.

You can get the iso here:
