    Are you sure the IP address is both correct and is not in conflict with another machine on the network?

    Can you verify the router/gateway's IP on another machine (ping 192.168.1.1)?

    Everything else seems okay. If you are sure the IP/gateway is not problematic, please check the firewall status in Ubuntu -
    Code:
    sudo ufw status
    By default it is "inactive".
    Then try -
    Code:
    sudo ifconfig eth0 down
    sudo ifconfig eth0 up
    As an aside, your network card is Realtek RTL8111/8168B, for which the correct driver is already included in the kernel (r8169) and is loaded. So tg3 or broadcom or any other drivers are neither required nor would work for your card. It seems you tried some random stuff without realizing what it is meant for.

    Did you make any other changes to your system?

    PS:
    Please use code tags to preserve the formatting of the outputs. It makes it easy to read and follow.
    If you are saving the outputs in a text file, then opening it on a windows machine, make sure to change the "Line Ending" to "windows" mode. Then while posting, click on # at the top of edit box to auto-generate 'Code' tags, and copy-paste the outputs in-between the tags. Follow the "Code tags example" link in my signature to see an example 'how to'.

    I can ping 192.168.1.1 And there's no conflict with other device addressed. I checked (again) by accessing my router -- no conflicts with .88 (or .99, which I tried before). And thanks for pointing out that the NIC drives are good -- I was considering buying a new card.

    Trying the power cycle (again) now.

    Thanks.

    No love after setting to auto DHCP and doing the power cycle.

    I checked all cables with ye olde trusty network cable tester with tone generator -- cables are fine.

    Load 13.04 iso?

    I believe you did it all from a different machine?
    You did not tell us about ufw status. Is it inactive?

    ..or whatever Live CD/USB you may already have. Just to rule-out any possibility that the installed OS may be at fault.

    Boot with the Live CD/USB, and see if it picks up an IP via DHCP. If not, try assigning an IP manually to see if it connects then. Let us know if it does or doesn't.

    Please use code tags - if you are using New Reply button - highlight text and use the # button in the text box header.

    If using Quick Reply then [code] at the beginning and [/code] at the end.

    No problems at all ! Glad to know that our basics were always telling us the truth. You know, reaffirmed our belief - "Never ignore the fundamentals!"

    As for marking as [Solved], yes you should do so now. Just follow the link BlinkinCat gave you to see how.
