    What chipset is your card and what driver are you using in case you know?

    Ah... bad news. I don't think the rtl8180 supports WPA... You need to do some further research, but I have not heard much good stuff about it (at least in that respect).

    Hey All -
    so i assume there is no way of getting on the wpa network onless you have admin rights on it and can change the settings of the router?!

    wish all a nice december!

    Thanks for the howto. It worked for me, but I needed to do the below:

    -
    • apt-get remove network-manager
    • apt-get install ndiswrapper-utils-1.9 ndiswrapper-common
    • download the driver file from linksys. It's an EXE file, but you can unzip it and find the driver for version 4.
    • depmod -a
    • modprobe ndiswrapper
    • ndiswrapper -i <version 4 .inf file>
    • blacklist the included rt2x00 and rt2500 drivers. Edited /etc/modprobe.d/blacklist and added the following at the end of the file:
      Code:
      blacklist rt2500usb
      blacklist rt2x00usb
      blacklist rt2x00lib
    • - add ndiswrapper to /etc/modules
    • - add the following to /etc/init.d/rc.local
      Code:
      /etc/init.d/networking restart
    • - reboot

    Yes, that's pretty much it. You need to know the network key or have access to the router. Two options in fact.

    The network key is the secret WPA passphrase if you know what I mean. A password that lets you access the wireless network. Have you got it?

    Wow this howto is getting long. Anyway, I got the wpa going a few months ago but it was not consistent. I tried again with new ndiswrapper, but have no success. iwlist -scan shows all sorts of networks around on eth1, just not mine. I changed wlan0 to eth1 in the interfaces file, but that did not help. Are there any other diagnostics that I could try?

    Man, that's sort of strange. You have the ability to see other networks but not your own? How odd is that?! Would you mind posting the results of:
    sudo iwlist scan
    Let's see what is going on... What hardware have you got?

    I have an emachines laptop running 64-bit Gutsy (netbc564 driver), dlink 524 router. I rebooted the router and now I can see my MAC address listed, also the iwlist scan shows my network, though as cell 05 and not on top as I would expect. strange thing is that there's also an eth1:avahi. I had this before and it seems to be an indicator of some dysfunction. So although I seem to be connected, there is no transmission of data once I unplug the network cable and disable eth0.

    rolf@ubuntu:~$ iwlist scan
    lo Interface doesn't support scanning.

    eth0 Interface doesn't support scanning.
