    It's okay, just skip the first 2 line and start on ./scripts/driver-select


    Now is how can I make the wireless up

    Re: Wired ethernet not getting detected

    jamesisin: you only need the first two commands if you don't have a compiler and other build dependencies installed. Apparently you already had a compiler installed on your system, since the rest of the commands worked without issue. So you're all set.

    mbpram: what output do you get from these commands (run them in this order, with your ethernet cable plugged into your router):
    Code:
    dmesg | grep -ie realtek -ie rtl -ie r8 -re 8136
    lshw -C Network
    sudo ifconfig eth0 down
    sudo ifconfig eth0 hw ether 00:1a:2b:56:78:09
    sudo ifconfig eth0 up
    sudo dhclient eth0
    Some commands may have no output.

    That that's all well and good, but keep in mind that anyone attempting to get this nic working won't have Internet access either. You may want to put a note on the original post where you added these instructions for less tech-savy users.

    Yes, I agree that would be helpful--although I originally wrote those instructions for one user and had no idea so many others were going to latch onto this thread (though I'm glad it's proved to be helpful). It was never supposed to be a tutorial or how-to for the masses. So please don't be too harsh with the criticism; I'm doing the best I can here

    3.sudo ifconfig eth0 down
    4.sudo ifconfig eth0 hw ether 00:1a:2b:56:78:09
    5.sudo ifconfig eth0 up

    After executing these commands i was able to connect with the internet using the wired network.... Still my wireless does not work. So i installed the wireless drivers, then the wireless network got detected but wen tried to connect it showed connecting for may be 20 min or so n finally did not connect. Also wen i rebooted, the wired network was again down. If i execute those three commands again i was able to get the wired network.

    6.sudo dhclient eth0

    Re: Wired ethernet not getting detected

    mbpram: those commands had you set a MAC address manually for the ethernet. It seems that it works once you do this. You could write a boot script to set the MAC address automatically when your computer boots, so that it should connect on its own. To write the appropriate boot script, type these commands:
    Code:
    sudo -s
    cd /etc/init.d
    echo -e "ifconfig eth0 down\nifconfig eth0 hw ether 00:1a:2b:56:78:09\nifconfig eth0 up" > ethernet-fix.sh
    chmod +x ethernet-fix.sh
    update-rc.d ethernet-fix defaults
    After this the ethernet should just work whenever you boot your computer. As for the wireless, please try connecting, then post the output of:
    Code:
    lshw -C Network
    dmesg | grep -e wl
    sudo iwlist scan

    Re: Wired ethernet not getting detected

    mbpram: when you type "lshw -C Network" you need to wait a second and it should show output. It should definitely show you something so please give it another try.

    As for the other command, it should be "dmesg | grep -e wl" with a lowercase L as the last character, not the number 1. Please try that again as well.
