    I am running the newest prefinal5 (05. June) and now I am testing with wpa2 and windows xp SP2 + WindowsXP-KB893357-v2-x86-ENU.exe.

    How can I see, if I am using wpa2 or wpa? In the Web GUI of my Router (WRT54GS) I can only choose wpa and AES + TKIP. The same with windows.

    My secured wireless is working fine, but I don't know, if it is wpa or wpa2.

    Does anybody setup a wpa2 wlan? Is there any howto??

    Once you have that enable and have your passphrase set windows will automatically detect you are using WPA2.

    Now I choosed WPA with AES + TKIP. Everything works fine.

    I thought, there will be any notice in windows, that I am using WPA2. But windows don't show anything.

    Not only do the wireless card drivers have to support it (such as the broadcom drivers) but the WRT firmware must also, which the current pre5 build does not. A former pre5 build did, but it was removed because of problems with the new wireless driver in the router.

    If I set my router to WPA TKIP+AES and my nic to WPA2 (using broadcom drivers), it does not connect. WPA-psk works fine. Something is different.

    how can you set your nic to wpa2? I don't have this option. I am using a pcmcia linksys card (WPC54G).

    You can't use the linksys drivers (yet). I have a WPC54GS and the option is there only with the Broadcom drivers.

    This thread has information on the driver, but you have to modify the inf file...I think someone there has the modified file but I did it myself.

    Hey Filibuster,

    WPA indeed doesn't seem to be the same as WPA2. "TKIP+AES" is just an encryption-setting, available on both, AFAIK. Here is the relevant and slightly edited part of a posting I did to the HyperWRT-forums on the subject:

    With "TKIP+AES", clients will be able to use TKIP as well as AES to connect. Please note that, by design, all broadcast/multicast-traffic will use TKIP and only unicast-traffic will use the encryption chosen by the client. This is done because all clients need to be able to decrypt broadcasts and the only crypto supported by all possible clients will be TKIP.

    I installed the new Broadcom driver for my WPC54G12 card. Now I am able to choose WPA2 and WPA2-PSK.

    Does the new prefinal 5 supports WPA2? Any comments from the developer? Thanks.

    with wpa2-psk I can't connect to my WRT54GS with prefinal 5 (05. June).

    Seems that is not working right now.....
