I have installed Ubuntu 10.04-64 bit ( Lucid Lynx ) on my Dell Inspiron N4010 laptop. I'm unable to detect my wired ethernet. :mad: I tried searching for it extensively but I think I was unable to make sense out of the posts already present. I know this has something to do with the need to install the correct drivers. I Also posting the output of few popular commands which I'm sure I would be asked to execute. Ok, base on this talks, finally i have the solution: My ethernet hardware seems to be quite new and doesn't have a driver built into Ubuntu as of yet. However, there's a driver included in the compat-wireless stack that you can use (I have no idea why they included an ethernet driver in compat-wireless, but according to these emails, someone did). To download, compile and install the driver, first go to http://linuxwireless.org/download/compat-wireless-2.6 and download the file named "compat-wireless-2.6.tar.bz2" (you can't download it in the terminal because of anti-hotlinking). Save it to your desktop. Then run these commands: [code lang="bash"] sudo apt-get update sudo apt-get install build-essential cd ~/Desktop tar -xjvf compat-wireless-2.6.tar.bz2 cd compat-wireless* scripts/driver-select atl1c make sudo make install [/code] Then reboot the Lucid. Hopefully your ethernet will work automatically after reboot; if not, run: [code lang="bash"] sudo modprobe atl1c [/code] And Yo !! Wired ethernet is now up n running !!
