    Can't connect to ethernet or wireless.

    Hey, I have a Toshiba Satellite L645D-S4030 running on Ubuntu 10.04. When I plug an ethernet cable into the ethernet port, simply nothing happens, and when I try to connect to my wireless network, it connects but there is no actual internet available. I'm sure the wireless works as I'm on an older model Toshiba Satellite and it connects fine (running Ubuntu 10.04 as well.)

    I tried to follow the procedure in the stickied thread, so when I type in these commands, here's what shows up:

    There's an option to "Disable smilies in text" - I turned them off for you.
    Using the CODE tags is another way to prevent smilies from sneaking in...

    Re: Can't connect to ethernet or wireless.

    Hi,

    Can you ping your router? It's probably at 192.168.1.1 but worth confirming that if it doesn't reply.

    If you can ping your router, then maybe it's a DNS issue. What's the content of '/etc/resolv.conf' ? It should have a line that begins with 'nameserver' followed by the IP address of your DNS server - that's more than likely your router, which is the IP address you pinged above.

    Regards,

    Gareth

    Same problem here.

    ifconfig eth1 reports device not found.

    Re: Can't connect to ethernet or wireless.

    Rhodie,

    Should you have a device 'eth1'?

    Run
    lshw -c network
    at a shell and post the results.

    Also consider whether your issue is the same as that of the originator of this thread. If not, maybe start a new thread instead.

    Re: Can't connect to ethernet or wireless.

    There's no eth0, eth1, eth2, etc.

    It says network UNCLAIMED for the ethernet controller. I'm guessing it may be a driver issue. Atheros Communications AR8152 v1.1 Fast Ethernet.

    Yes, it's the same issue in that it's Ubuntu 10.04 on a Toshiba Satellite L645D that doesn't recognize the wired connection and has no internet available on the wireless connection. For now, I'm focusing on the wired connection.

    This is a new install. Both wired and wireless worked fine under Windows 7.

    I wonder if this is relevant. http://groups.google.com/group/linux...d76ec098e0b5ed

    Re: Can't connect to ethernet or wireless.

    lspci -k
    should show if kernel drivers are loaded or available for all your devices. If none is shown for your ethernet controller then
    lspci -nn
    will show the PCI id and name of all your devices. Compare the PCI id of the ethernet controller with the one in the atheros webpage you found.

    How about this:-

    It seems that the ethernet driver might be in a wireless stack!
