    Can you post the output of :
    Code:
    ifconfig -a
    route -n
    cat /etc/resolv.conf
    ping -c3 62.108.1.66

    Can you try the following in a terminal on the Ubuntu machine :
    Code:
    sudo dhclient
    ping -c 62.108.1.65
    If that works, then it looks like it's a Network Manager problem, you might want to see whether wicd gives you better results instead :
    http://wicd.sf.net

    If wicd then works for you, file a bug-report about Network Manager.

    Re: Cant connect to the internet

    Get a Netgear WPN511 card, see my entry:

    CAN connect with Netgear wpn511

    My computer is a IBM T30 and running Ubuntu Hardy Heron, 8.04.
    Here is what I did after trying for quite some time to get my wireless card to work. I found this on some Linux website, and it WORKS !!!!!!
    In my T30, I had to remove my internal WiFi card.

    1. Plugged in my netgear WPN511 card. It started flashing 2 light alternately.
    2. (Applications, Assessories, Terminal) Typed in:
    sudo iwconfig atho essid <your ssid here>
    sudo iwconfig ath0 key <your hex key here> restricted
    sudo iwpriv ath0 mode 3
    sudo iwpriv ath0 authmode 2
    sudo dhclient ath0
    3. After the second iwconfig, both lights started blinking together.
    4. I could login to my website.

    I had another Netgear card, WG511U and that works too.

    At the moment I have to write these instructions everything time the computer is booted. I have a question, where do I put these instructions to automatically when booted it is included.

    /etc/rc.local is an option.
    First read carefully what is already written in that file.

    Re: Cant connect to the internet

    I've found a bug where 8.10 doesn't like nameservers on the local network. Sometimes.

    If you can see you router, find out the address of your ISPs name server.
    Add it into /etc/resolv.conf
    ie: nameserver yourdns
    See if this improves things,

    NOTE: NetworkManager will try to overwrite it next time you boot.
    Possible solution:
