    Has a ethernet and wlan , problem pinging



    I have a ethernet card ( eth0) and wlan on my laptop. I normally connect to Internet using wlan. Now I have connected my old pc to my laptop using a lan wire. When I try to ping it , it seems that my laptop tries to find the old pc on my wlan ntw. How can I ping my old pc using eth0??

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    The easiest way is to disable the wireless when you are connected to the wired network. FWIW, my Dell laptop has a bios setting that tells it to disable wireless when it detects a live ethernet connection on bootup. Works great. I only have to disable the wireless network if I connect it to the wired network while it is already booted up.

    but the problem is that wlan gives me Internet connection and at the same time I want to be connected to the lan also.

    I think that to have two NIC's working at the same time, they have to be on different sub-nets. You also need to manually configure this, as the NetworkManager program doesn't seem to allow this.

    Ah! Different problem. Are these ports connected to different networks or subnets?
