That's strange. We may need to try a different driver. The one you were using was called 'b43'; let's try the STA driver instead, which is called 'wl'. To install the STA driver, type:
Alternatively, you should be able to install the driver graphically using the utility at System>Administration>Hardware Drivers.Code:sudo apt-get update sudo apt-get install --fix-missing bcmwl-kernel-source bcmwl-modaliases
You will need to be connected to the Internet for this to work, so please make sure you can browse websites before trying to install the STA driver.
Once the driver is installed, reboot. If the wireless still doesn't work, try typing "sudo ifconfig eth1 up". If it still doesn't work even after that, please post:
Sorry this is turning out to be difficult, but thanks for your patience.Code:ifconfig iwconfig lshw -C Network dmesg | grep -e b43 -e wl -e eth
lo no wireless extensions.

Do you have an Ubuntu installation CD? If so, you can install the driver from there. First you need to put your CD in the drive, then go to System>Administration>Software Sources and, under the "Ubuntu Software" tab, enable the use of your CD as a repository. After that, try running again:
If this doesn't work, you may also be able to get your wired Internet working by typing:Code:sudo apt-get install bcmwl-kernel-source bcmwl-modaliases
After typing those commands, try opening Web pages. If that works, you can download the STA driver using:Code:sudo ifconfig eth0 up sudo dhclient eth0
Code:sudo apt-get install bcmwl-kernel-source bcmwl-modaliases
selected CD ROM as repository,this is what I got...

It looks like it didn't work on the first try because the package 'patch' was not installed, which it apparently needs. Please make sure your Ubuntu CD is still enabled to be used as a repository, then try:
Code:sudo apt-get install build-essential patch sudo apt-get install --reinstall bcmwl-kernel-source bcmwl-modaliases
Hi rbisawa, on Pytheas post hes asked to enter:
sudo apt-get update
My problem is that I dont have access to any network since my wired and wireless cards are not recognized.
How did you do?
julio prada: we can find a way to activate your wireless even if you don't have wired Internet access, but first let's make sure your situation is actually the same as that of the other posters in this thread. Please post the output of these commands so we know which hardware you have, etc.:
If you have different hardware and a different problem, I'll ask you please to start a new thread so that this one doesn't become too convoluted, and I'll help you in your new thread.Code:lspci -nn lshw -C Network dmesg | grep wlan
Also, keep in mind that you can save the output of the commands to a text file, then use a USB disk or CD to transfer the file to a computer with Internet access, so that you can copy the output to this forum.
