There are also instructions here for installing a better version of the driver that might solve the problem with the LED not coming in. I'd recommend giving them a try; they probably can't make it any worse.

    You could also try these commands to connect from the command line (with encryption on your router still disabled):
    Code:
    sudo -s
    ifconfig wlan0 down
    iwconfig wlan0 channel 6
    iwconfig wlan0 mode managed
    iwconfig wlan0 essid "WEST6013"
    ifconfig wlan0 up
    dhclient wlan0
    If things go the way you want, that last command will result in you being assigned an IP address (assuming your network uses dhcp; if it doesn't, let me know) and you'll be on the Internet.

    Let us know if this gets you anywhere.
    when i try to put in that 2nd line of code, i get this:
    root@tsk84eva-laptop:~# ifconfig wlan0down
    wlan0down: error fetching interface information: Device not found

    FYI, i've just plugged in an ethernet cable and was able to get online without an issue

    You made a typo There should be a space between "wlan0" and "down."

    I am having the same problem as the guy who posted the original problem. I also have another problem, When I attempt to connect to the internet, it shuts down my 1000SW Home Portal too.

    It didn't work the way you wanted because dhclient wasn't able to fetch an IP address. You could try setting one statically by going to System>Administration>Network, if you know enough your network to know how to configure it.

    Otherwise I'm not sure what else to try--it looks like your card works fine at all stages until it gets to the part where it needs to fetch an IP address, and I don't know why. It doesn't seem to me to be as issue with the card being turned off, because it doesn't make sense for it to be able to see networks and request IP leases if the wireless is off.

    I would recommend giving ndiswrapper a shot but you said you already tried that and it didn't help. Are you sure you configured it correctly?

    Re: Wireless Network Problem

    Alright, try with ndiswrapper again and if you need help, post. Make sure you blacklist the native Linux drivers or ndiswrapper won't work. I'm not sure which drivers to blacklist for your card, but if Google doesn't tell you let me know.

    Re: Wireless Network Problem

    Ndiswrapper didnt work as you said earlier because there is a conflict between ndiswrapper and ssb in Hardy. I have posted the solution in this other thread, it should work for your card as well (use your windows driver). Try it and post the results here. Thanks
