    BTW, sorry for the noob question, but it's hard to browse through 170+ pages: what's wrong with WEP? All my neighbourgs seem to use it.
    Good point. My recommendation is that you don't use WEP at all as it is highly insecure. An experienced user can crack WEP in a matter of minutes (I have written a tutorial on it for educational purposes).

    WPA or WPA2 is the way to go. WEP is highly flawed and should not be use any longer.

    Hmm, sounds like fun to try, can I see the tutorial? How bad is the possible exposure? Can someone get to my Windows shares, for example, or is it just traffic snooping?

    It's a lot of fun. To test your own network's security, give it a go:

    Yes, somebody could also get access to your shares... or anything else that isn't password protected. It's not very likely but it's a risk one can easily avoid.

    weiman01,

    I posted on kevdog's thread as well but i really need to get this fixed ASAP so I will ask you as well. (kevdog also hinted that he isnt very familiar with Ra and intel chipsets...which I am so luckily blessed with):

    I have been trying to get your tutorial to work for the past few hours and I can make it work if I take the encryption off my network. Since that is not the most desirable way to communicate with my router, I've been trying to get my wireless card to connect via WPA-Personal encryption.

    Im using a Ra-based chipset (I think)

    when I type:

    sudo iwpriv wlan0 set AuthMode=WPA-PSK

    which returns: "Invalid command: set"
    this happens with all the iwpriv commands.

    please assist. this is for my little brothers computer and I am leaving on sunday ( i dont think they will be able to get it running without me)

    also my network manager doesnt appear to work. when I connected to the unencrypted network, it didn't reflect it on the top right corner of the screen. it still had the red x.

    Thanks

    I had problems with ralink wireless adaptor too and Network Manager didn't work correctly so manually configured the network interfaces file.

    Like Wieman01 says, plenty of info if you please.

    Thanks for the response, I fixed it last night. I just had to change the specified driver in the network-config application. it worked with the generic linux driver "wext".

    Yes, Ralink work with "wext" nowadays. Glad you got it fixed.

    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    Sony PCG-V505BX (WPA not listed)
    Does anyone else here have this laptop? I have Ubuntu installed, but cannot connect to my home wireless network when I have it set to WPA security. It successfully detects the network, but when I try to connect it doesn't list WPA as an option. I can plug in my USB WIFI stick and then connect to WPA, but not with the internal hardware in my laptop. I can also switch the network to WEP and connect with the interal wireless card alone, but I don't really want to do that. Does anyone here have a suggestion for me?


    I believe this is the actual wireless hardware that comes with the computer:

    LAN Express AS-IEEE 802.11 miniPCI Adapter



    Here is what I came up with from Ubuntu:
