    change the gateway to 192.168.1.1 and the destination to default.
    Code:
    route add default gw 192.168.1.1
    ping 192.168.1.1

    btw : what router(model) are you using?

    Re: Wired Connection not connecting to router

    How are you connected to the internet?

    Are you using the same computer and router as the one you are having problems with? If yes is this in Ubuntu or are you booting into another OS?

    It appears that your router is not responding.

    Most likely causes for this are

    1. Faulty router - unlikely if you are using this router to connect from the same or another computer

    2. Faulty connection - unlikely if you are using the same computer, even if you have to boot into another OS

    3. Misconfiguration - If you can connect from another computer or OS it may be worth checking its settings

    4. Firewall getting in the way for example

    Tell us more about your setup and we may be able to advise more

    Re: Wired Connection not connecting to router

    How are you connected to the internet?
    - ethernet from desktop onboard NIC to modem/router.
    Are you using the same computer and router as the one you are having problems with? If yes is this in Ubuntu or are you booting into another OS?
    Yes I am. I have a dualboot with windwows 7 and ubuntu. I'm Booting into ubuntu on my desktop

    It appears that your router is not responding.

    Most likely causes for this are


    1. Faulty router - unlikely if you are using this router to connect from the same or another computer
    - works fine in windows 7 and with xbox360 & windows 8 laptop.

    2. Faulty connection - unlikely if you are using the same computer, even if you have to boot into another OS
    - Plugged in a new ethernet cable and interface on the router/modem.

    3. Misconfiguration - If you can connect from another computer or OS it may be worth checking its settings
    - I could post my router settings etc?


    4. Firewall getting in the way for example
    - Firewall disabled.

    Re: Wired Connection not connecting to router

    Most likely problem is configuration so to find out what your working windows 7 is set to

    click the start button and type cmd in the search box

    In the window that opens type

    Code:
    ipconfig /all
    Post all the results back here

    Now with your Ubuntu boot open a terminal and give us the output of

    Code:
    cat /etc/network/interfaces
    This probably needs to be edited and hopefully we will be able to tell you what it should contain.

    Re: Wired Connection not connecting to router

    I can't see why this isn't working

    Your windows machine is set to get its network settings automatically by DHCP and its getting the following settings

    Code:
     
    Physical Address. . . . . . . . . : BC-5F-F4-08-03-6C
    DHCP Enabled. . . . . . . . . . . : Yes
    IPv4 Address. . . . . . . . . . . : 192.168.0.25(Preferred)
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.0.1
    Your Ubuntu machine is set to get its network settings automatically by DHCP and its getting the following settings

    Code:
    eth0      Link encap:Ethernet  HWaddr bc:5f:f4:08:03:6c             
              inet addr:192.168.0.25  
              Bcast:192.168.0.255  
              Mask:255.255.255.0
    And the default gateway is

    Code:
    sean@sean-ubuntu:~$ route -n Kernel IP routing table 
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface 
    0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 eth0
    These are the same so it looks like configuration is working properly.
    so you should be able to ping not only the router but anywhere on the network or internet.

    Is the ubuntu firewall enabled? to check what's the output of

    Code:
    sudo ufw status; nm-tool

    Re: Wired Connection not connecting to router

    Hi

    I notice in your earllier post you show the output of route add and del commands but you get an error messeage "SIOCDELRT: No such process"

    An identical error appears in this thread:

    http://ubuntuforums.org/showthread.php?t=1318743

    which is solved by running


    Code:
    sudo [text editor of choice] /etc/hosts
    then adding a line saying

    Code:
    192.168.0.25    sean-ubuntu
    on line three at the end of the ipv4 block.

    and restarting the networking service with


    Code:
    sudo service networking restart
    Seems to have worked there so maybe give that a shot.
    Hope this helps!

    Barry
