    Yesterday, I was out of town and went to my sister's place. I didn't have a lot of time to play with my sister's router and laptop that has Vista. The Tomato firmware version is 1.05. If I select the 'WPA / WPA2 Personal' in the optional of 'Basic' -> 'Wireless'. Her laptop with Vista will not connect to wireless unless I set it to 'WPA Personal' or 'WPA2 Personal' and it will working to get Vista to connect to wireless. Is it a known issue? I do realized that the firmware is old, but I don't see anything in ChangeLog that related with WPA/WPA2 in Tomato firmware website.

    The reason why I want to use 'WPA / WPA2 Personal' because one of her roommate has no control to update her WinXP to have that WPA2 on her laptop. While my sister's laptop can uses WPA2. I am wondering if it's possible to have both WPA and WPA2 on a router by Tomato firmware?

    I won't be able to play with her router and laptop in few weeks, so I am hoping if someone in here know the answer to it for I can solve her problem when I visit there again. Thanks.

    So are you saying it _doesn't_ work with WPA/WPA2? Reread your post but it's a bit unclear.

    Anyway, no problems on 2 different Vista systems here on 1.13. May be a driver issue on your laptop, or an issue with that version of Tomato, I'm not sure...

    Make sure to set TKIP / AES for the other option? I believe WPA uses TKIP while WPA2 uses AES..?

    I am not very good on English, but I will try it again.

    -If I select 'WPA / WPA2 Personal' option in Tomato firmware and Vista can't connect to it. It doesn't work.
    -If I select 'WPA Personal' option in Tomato firmware and Vista can connect to it. It works.
    -If I select 'WPA2 Personal' option in Tomato firmware and Vista can connect to it. It works.

    Umm, I am confusing.. What is the difference between 917021 and 893357?

    Anyway, read my post again, my sister's roommate doesn't has any control to update her WinXP. It's not her laptop, which it's company laptop. It's why I am asking if that 'WPA / WPA2 Personal' option work for anyone. :)

    I believe it was selected on 'AES' option. I can try to change it from 'AES' to 'TKIP / AES' with that 'WPA / WPA2 Personal' to see if it works better. Thanks for hint.

    By the way, my sister laptop is Dell e1505 with Dell's wireless device (not Intel).

    Your problem is probably due to the Vista wireless driver being too clever for its own good. The firmware being "old" has nothing to do with it, as the WPA nor the WPA2 standard has changed since Tomato 1.05 was released.

    The principle is this: If Tomato is set for WPA/WPA2 then Vista must be forced to one of the 2; I forget if Vista has this option, but Vista should not also be set to WPA/WPA2 - it should be set to either WPA or WPA2.

    Also, on the encryption scheme: if Tomato is set for TKIP/AES, Vista should be forced to either TKIP or AES, not TKIP/AES.

    Best is probably to set Tomato to WPA/WPA2 with AES, and Vista to either WPA or WPA2, but with AES.

    917021 is newer. 893357 is the old version.

    If you fix the XP machine then you don't have to worry about Vista or Tomato. You could in theory crack the password, or merely extract the changed files and manually overwrite the ones they replace in the system recovery console. Though it would probably be easier if you just had her go to her company's IT admin and say:

    "Hi, I am having trouble connecting to a WPA2 wireless, could you please install this fix from Microsoft? <link> Thanks!"

    Don't use TKIP, it is generally weaker. You can use AES with both WPA and WPA2.
    I have heard of Vista having problems wpa-aes while ipv6 support is enabled with the wireless connection. Try disabling ipv6 support on the Vista laptop and try again.
    Take these steps:
    1) disable ipv6 (if you google disavle vista ipv6, you will get immediate results).
    2) set your router to WPA-AES, and connect the Vista laptop to the router.
    3) set the laptop to autoconnect to the home network when it is in range.
    4) try changing the router to WPA/WPA2 mode, and see if it works.
