    Have you tried using this post? According to the link there you should be able to use method 2b or possibly 2e (based on the numbers - 14e4:4315 you've quoted). More up to date drivers can be found here for b43/b43 legacy as a large change was made early summer of this year.

    I wish I had seen the above post before I proceeded, but I just installed ndiswrapper and configured it to use the driver specified in step '2e' of the instructions you are referring to.

    I am connected right now with ndiswrapper, but am using an unencrypted network at a coffeehouse. I'll be making my way back to campus here in a bit to see whether or not I can indeed connect to the wpa2 enterprise network there. fingers crossed.

    Man, I sure wish i didn't have to use ndiswrapper for this, but I guess this rigging job will have to do, if it works.

    If this is successful, I'll post back shortly.

    OK, it appears that ndiswrapper has done the trick.

    I am now at a (ridiculously crowded) coffeehouse on campus, and network-manager connected to the university's network immediately upon this Mini 9 booting up.


    As an additional, confusing note, I had brought a USB wireless adapter along with me this morning as a backup. It has a Ralink chipset and uses the rt2500usb driver, but even trying to connect to the university's network with that adapter caused 3 hard lockups in a row before I gave up.
    I don't understand this as this same adapter connects to this network with no problem at all when using my other laptop... ah, the frustrating world of wireless+Linux.

    Peace.

    Kevbert, thank you for the reply; unfortunately, this chipset isn't supported by any open source implementation.

    From the B43 site: http://linuxwireless.org/en/users/Drivers/b43

    Note: Broadcom has used some of the BCM43XX designations for more than one flavor of card. To tell for sure if your card is supported, use the command 'lspci -n' and find the line that has the string "14e4:XXXX'. If XXXX is 4301, 4307, 4311, 4312, 4318, 4319, 4320, 4321, 4324, or 4325, the card is supported. All others are NOT supported.

    Notice that my card shows up as 14e4:4315. Confusing, I know. I don't know how the Broadcom developers keep things sorted with such silly naming practices.

    Have you seen this ? It looks like you may need to turn off WPA2 support if you want to get WPA to work. Couldn't find drivers on the Lenovo website unless it's included with the ethernet drivers.

    Thanks for the link. I wish they would have posted detailed hardware information. Lenovo could have changed wifi cards since then.

    Have you tried connecting without network manager? I am still wondering if network manager is fighting with it. If you turn it off, you might need to check in the Terminal that it is off:
    Code:
    ps -ef|grep Network
    and make sure that there are no Network Manager processes running[/code]

    Yes, I have tried with and without Network Mangler. No Luck. I just installed Jaunty Alpha 2 and have the exact same problem. It appears that this build is using the most recent driver from Broadcom (not sure how to confirm).

    old version software

    Updating a program is usually a good idea,but in some cases its not good. That is what we're here for! There have been several instances where a new release of a program is not always good.reason is several factors.

    JRon were you able to get this device working? I have a Lenovo S10 with the same device and was able to get it working using ndiswrapper via these:

    Wireless still wouldn't work until I pressed the "Wireless" button on the laptop. In Windows there is an on screen display saying whether the button is disabling or enabling wireless, but with Ubuntu it seems to turn wireless on/off without any display
