    Problem getting LInksys router to work with Ubuntu

    Hello

    I've been using Ubuntu for about a month (on and off with OSX), so I have no idea what I'm doing. I've never had to deal with networking problems in Ubuntu, since everything was just automatically set up connecting my modem directly to the PC's onboard ethernet port.

    I have a Linksys WRT54G2 router that I'd like to use with the Ubuntu PC and my Macbook (both wired connections). Wireless would be a plus, but isn't completely necessary at this point. If I connect my modem to the router and the router to the Ubuntu PC, it says I'm connected (on "Auto eth0") but I can't access any sites. I've tried to create new configurations in Network Connections and messed with them a bit, but I don't really know what info to enter (for MAC address, DNS servers and IP if I need to do it manually, etc.).

    I've Googled and searched this forum for a solution for the past 2 hours and still can't figure it out..so sorry for the noob question. Please keep in mind that I have absolutely no experience if you post..

    Thanks in advance.

    Re: Problem getting LInksys router to work with Ubuntu

    Did you want the output of ifconfig and the other two when I'm connected directly to the modem or connected through the router?

    Looks like a route problem or a DNS problem.

    In general, the DNS address should be set to point at the router (which says "beats me" and forwards the DNS request to the real DNS servers that it knows about (given to it by your ISP on the wan side)). From your IP of 192.168.1.44, I am assuming your router should be at 192.168.1.1 - you should be able to log into the router and check the status etc (this also verifies you are talking to it).

    The instructions said Windows NT or better, so I installed Ubuntu Linux !!

    Re: Problem getting LInksys router to work with Ubuntu

    Connected (but not being able to load sites) with the router, I can type 192.168.1.1 in firefox and get to the router settings. Here's the output of ifconfig when connected through the router (I think the last one I posted might've been while it was connected directly to the modem):

    eth0 Link encap:Ethernet HWaddr 00:e0:4d:01:50:4a
    inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0

    collisions:0 txqueuelen:1000
    RX bytes:3945732 (3.9 MB) TX bytes:597373 (597.3 KB)
    Interrupt:16 Base address:0xb000

    lo Link encap:Local Loopback

    inet6 addr: ::1/128 Scope:Host
    UP LOOPBACK RUNNING MTU:16436 Metric:1
    RX packets:8 errors:0 dropped:0 overruns:0 frame:0
    TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:0
    RX bytes:660 (660.0 B) TX bytes:660 (660.0 B)


    And here are the router settings @192.168.1.1:

    Automatic Configuration (DHCP)

    Router Name: WRT54G2
    Host Name: (empty)
    Domain Name: (empty)

    Here is the output of cat /etc/resolv.conf:
    # Generated by NetworkManager
    domain myhome.westell.com
    search myhome.westell.com
    nameserver 192.168.1.1



    And the output of ping 72.14.205.100:
    PING 72.14.205.100 (72.14.205.100) 56(84) bytes of data.



    When messing around in Network Configuration, should I be working under Wired or DSL?

    Maybe you should set a static DNS to your ISP's DNS server
