    Wireless won't connect

    Hi,
    just trying out Xubuntu 8.04 for the first time. I have a Dell Inspiron with PIII 600 and 512mb ram. I installed the OS and was able to connect immediately with the pcmcia nic, but when I install the wireless card I can't get it to connect to the internet.

    It is a DWL-G650 with an AR5212 chipset. The driver is loaded, and I can see by the blinking lights that the card is powered. When I run in terminal iwconfig I get:
    lo no wireless extensions.

    wifi0 no wireless extensions.

    ath0 IEEE 802.11g ESSID:"Tuxnet1" Nickname:""

    I tried to follow the troubleshooting suggestions here:

    https://help.ubuntu.com/8.04/interne...hooting-device

    but when I try to open the systems > preferences > hardware, the preferences and beyond are not there. I don't see any other means of checking hardware installation in the applications menu.

    Can anyone give me some help as to how to get the wireless working? It seems like its about halfway there, almost ready to work but presently won't let me connect to the internet.

    Thanks!

    Re: Wireless won't connect

    does "sudo dhclient ath0" do anything for you?

    What are the addresses that wireless router is giving out?

    try to address your interface by hand:

    sodo ifconfig ath0 192.168.0.5
    route add default gw 192.168.0.1

    if 192.168.0.5 is your dhcp range and 192.168.0.1 is the address of
    your router.

    also post ifconfig output and try pinging your modem

    I tried to manually configure the address manually but it didn't work. I don't think that I understand how to find the correct addresses, even though I can log into my router via the browser and the ethernet connection.

    Keep trying!

    Re: Wireless won't connect

    I have the DWL-G650M PCMCIA wifi card installed on an old Dell X200.

    I had to use the windows driver shipped with the card using NDISWRAPPER in order to enable the wifi card properly.
    The gui application windows wireless drivers located under system/administration will help you configure the driver.

    I am able to use the card with Ubuntu Hardy Heron with no problems finding hot spots or at home.

    Re: Wireless won't connect

    Hi,
    thanks for the response. It seems like the Atheros driver may be working, but the wireless card isn't recognized by the computer so I can't get on the internet with it. I've used other linux systems, and I think my next step would usually be to make sure the card is recognized by the OS.

    I've looked for the windows wireless you suggested, but it isn't there in systems. Also, there is no tab for preferences > hardware, so I can't make sure that the card is being recognized by the computer. Seems like an OS problem to me, but truly I am not a computer expert and I could have it all wrong.

    Re: Wireless won't connect

    If you go into the Synaptic package manager and search for ndiswrapper you should find the package as it is a standard Ubuntu supported package.

    I hope that I am not steering you down the wrong path.

    If you are able to ping your wireless access point then there is no problem with the way your card is currently configured.

    If you are sure that your card is not recognized I would definitely try the windows driver / Ndiswrapper solution.

    Re: Wireless won't connect

    Hi,
    I thought that I would give your suggestion a try just on the off chance it was a driver problem, so I installed ndiswrapper with the windows wireless tools. Then I installed the windows driver for the wireless card. The driver is installed properly, but I am having the same problem. I can't get hooked up to the internet.

    It seems like the card isn't configured into the operating system or something, even though the drivers are installed, and the card is powered.

    Anyone have any thoughts? Why is there no way to check if the card is installed in the operating system from the system dropdown menu?

    Thanks
