    I'm using WPA2 and I don't know how to set it up. Here's everything that I can provide to help you:

    Can you please help me?
    Please also provide:
    sudo cat /etc/network/interfaces
    Does network manager list any other networks around you?

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

    Hi All-

    Any chance of a hand with my wifi? I've had it working fine on WinXP, using WPA-PSK/TKIP, which is all fine.

    Network manager doesn't want to play the WPA game (I don't think this is news to anyone!), and worse, often when I try to tweak the settings, the system crashes, and won't re-start, see : http://ubuntuforums.org/showthread.php?t=613133 I'm not alone!

    My network/interfaces currently only contains:

    auto lo
    iface lo inet loopback

    Device manager reports that the card is:
    Texas Instruments
    ACX 111 54Mbps Wireless Interface
    Bus type PCI
    Device Type / Capabilities unknown

    OK- I know this doesn't look right, but I am afraid to fiddle in case I get the crash, and then have to re-install (for the 9th time) when Ubuntu won't re-start.

    Please help a noob!

    Charlie

    Ok, let's do a scan first (post the results please):
    sudo iwlist scan
    What driver do you use? Did the adapter work out of the box?

    I'm afraid that I am not sure what drive I'm using- a complete Linux noob. Network manager sees the wifi adapter, and lists a handful of networks, which is what I would expect. Unfortunately, after trying some settings, the crashes and problems start. So I suppose that means that the driver isn't working correctly?!

    Cheers

    FokkerCharlie,

    if I'm not mistaken Texas Instruments
    ACX 111 54Mbps linux driver does not yet support WPA.
    (The module should be called acx)

    I guess you need to try ndiswrapper, and make use of the windows driver with it.

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

    Ok, this maybe sound like i'm quite lazy and didn't try it harder, but that's not riught...i really follow the original threat and only get this...i can configure my network only with wpa and broadcast essid. It works fine, but every time i restart my pc it's has some trouble to connect...on the other hand, i want to get the wpa2 secure connection, any clue?

    This is what i've tried and works (any change to this it doesn't works:
    auto wlan0
    iface wlan0 inet static
    address 192.168.1.100
    gateway 192.168.1.1
    dns-nameservers 200.69.32.5
    netmask 255.255.255.0
    wpa-driver wext
    wpa-ssid xxxxxxxxxxxxx
    wpa-ap-scan 1
    wpa-proto WPA
    wpa-pairwise TKIP
    wpa-group TKIP
    wpa-key-mgmt WPA-PSK
    wpa-psk c53ad64bde66e72384da57fe1536917e994ca4bfdc79bd7c30 9c76ca02aa9afe

    I'm a gutsy user with d-link DWL-G510 Rev C and a wrt54g linksys router

    Thanks and sorry for my lousy english...

    I am afraid you are right. Scanning lists a number of networks, but there is no mention of WPA secured ones. That generally means that the driver does not recognize them as such... bad news.

    So you are saying that you need to restart the network after a reboot? Please see post #2 of this thread for a workaround/solution.

    Have you tried WPA2 as well (RSN)? Were you any successful or did you have trouble connecting in that case?

    Wieman, ubalap, thanks for your help.

    I'll have a go with NDISWRAPPER.

    Hi again

    Just in case you're interested- I had a go with Ndiswrapper.

    It worked a treat, until I'd re-booted a couple of times, and then it stopped. I have no idea why. I am completely sure that I had not changed any configuration in the meantime- in fact I was starting and stopping the computer just to see if the WLAN would stay working! Same results with WICD and Network Manager.

    Anyway, maybe I'll ask in the Ndiswrapper forums for help there.

    Cheerio!
    Charlie
