    ethernet + wireless + internet

    Hi all, sorry for my bad english.

    I have a notebook with ubuntu 10.04 and I use NetworkManager to connect with a network.

    I want connect wireless and ethernet together, the wireless network give me access to Internet.

    I'm able to connect ethernet and wireless togheter, but when I activate the ethernet interface, I lose Internet connection. When I deactivate eth0, the Internet connection returns.

    eth0 Link encap:Ethernet HWaddr ----------------------
    inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0
    inet6 addr: ------------------------------- Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
    RX packets:5708 errors:1 dropped:0 overruns:0 frame:0
    TX packets:9291 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:2681548 (2.6 MB) TX bytes:3781313 (3.7 MB)
    Interrupt:17

    wlan0 Link encap:Ethernet HWaddr ------------------------------
    inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
    inet6 addr: ------------------------- Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1
    RX packets:20856 errors:0 dropped:0 overruns:0 frame:0
    TX packets:16920 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:19076796 (19.0 MB) TX bytes:2829063 (2.8 MB)


    So, if I'm connected to wireless I can navigate on Internet, just plug in ethernet, the connection remains, but I do not have access to the Internet (not just a DNS issue, because even not ping the ip of google) .

    Can you help me?

    This is my ifconfig listing

    As you can see, like your system, both ethernet and wireless are UP and RUNNING.

    Wlan0 connects automatically at boot up. I click on eth1 and it gets connected. I have just done this while accessing this forum and I am not disconnected from the internet. I can access sites other than this one. I keep my ethernet cable plugged in all the time.

    I notice that you do not have a inet6 addr. Did you blank it out?

    Both of your connections have an inet addr and they are different. Your are connected to the router by both connections as I am. I also notice that the Bcast address is different. This is not the case on my system. Is this the problem? I do not know.

    regards.

    Thanks for your reply.
    Maybe you are connected to the same LAN (router).
    I connect my notebook to two different router:
    - wireless: to connect in Internet (ip address 192.168.1.1)
    -ethernet: to connect another LAN (ip address 192.168.0.1)

    But when I'm connected togheter I loose the Internet connection (only the Internet connection).
