    Can't Connect to Netgear Wireless Router

    Hey,

    I'm still pretty new to Linux, and pretty stupid about computers. So, I run Ubuntu 10.10 on my Dell Gx270. Up until I got this new Netgear (WNR2000v3) router it's connected to the internet pretty ok through a modem. But so I got this new Netgear router, and it connects fine with the computer I run XP on, but even when I try to hook my computer that I run Ubuntu on to it directly with an ethernet cable, it doesn't seem to recognize any connection. I threw all the numbers available into the network manager thing (you know, name, password, IP address, netmask IP or whatever... all the secret numbers. all of them) and on the issue of connecting my computer still says, "Nope!"

    It can't seem to find the device for my wireless connection when I try the whole "ifconfig" command thing.

    Am I doing something wrong? Is there something else I could do to make this work? Please help a stupid recent Windows convert.

    Re: Can't Connect to Netgear Wireless Router

    You should not really have had to do anything. And you say you cannot connect wired
    or wireless. Try stopping and restarting the network manager. Should find if you set the
    router up right, which is more or less plug and play. Can put your default route # into URL and
    will bring router settings up. Did you right click on network applet and enable wired and wireless?
    Here is to turn on and off network manager to try and reset. Open a terminal and copy and paste one at a time.
    Code:
    sudo service network-manager stop
    Code:
    sudo rm /var/lib/NetworkManager/NetworkManager.state
    Code:
    sudo service network-manager start
    Remember hence where you come and pass it down.

    Thank you for your quick reply and your help!

    Restarting the network manager didn't seem to do anything.

    I do not know how to find default route number. Could you help me with that?

    default route is usually 192.168.1.0 or 192.168.0.1 . that will let you log into the router through a wired connection. Make sure all settings are set to default in network manager and make sure you're using DHCP and not manual settings.

    Re: Can't Connect to Netgear Wireless Router

    My router/modem came with a User Guide. Sure, it gave instructions for MS Windows but there was enough information to identify what Ubuntu needed to get a secure wireless connection to the router. Here is a quote:

    If you couldn't connect during step 4, go to your web browser's address bar, type http://192.168.1.254 and click Go or press Enter on your keyboard. You'll be asked to enter a Username & Password. The Username is admin and the Password is the Serial Number (found on the bottom of your Thomson Gateway). Check the Setup Sticker for confirmation of these. Once you have entered the Username and Password you'll be taken to the Thomson Gateway Configuration page.
    If you did not get information like this when you purchased the router, then you did not get good customer service. Accessing the router configuration page with a web browser will let you confirm if you have set Network Manager to the same encryption method as the router is set to. You will also need what is variously called the wireless key, the network security key, the WPA-PSK key or the pass phrase to allow network manager to connect securely to the router.

    Regards.
    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Re: Can't Connect to Netgear Wireless Router

    Let's look at a couple of parameters and see what's going on.
    I'm gong to ask you to enter some commands in a terminal and post the output here.

    First one:
    Code:
    lspci
    Second one:
    Code:
    lsmod
    Third one:
    Code:
    ifconfig
    copy the readouts from the terminal and post here.....use the # on the message board to wrap your results in code tags.

    Re: Can't Connect to Netgear Wireless Router

    OK then this shows all is good up to and including your ethernet card. So problem is router.
    Did you follow the instructions:"default route is usually 192.168.1.0 or 192.168.0.1 . that will let you log into the router through a wired connection". Try those IP numbers in a browser for router access.
