    Hello FreeBSD-users :),

    yesterday I installed FreeBSD-9.0-RELEASE-amd64 on my new Dell Inspiron 15R Special Edition and the wireless network card on the machine was not detected during the installation.

    The card is Intel Centrino Wireless-N 2230 and it is working fine on both Windows and Ubuntu-linux, but FreeBSD detected only the onboard ethernet card. Internet is working fine when the the ethernet cable is connected to the machine, but since it is a laptop it would be nice with wifi.

    So what can I do to make the wifi work? I am absolutely new to FreeBSD.

    Also when FreeBSD is running on the machine, the machine makes a lot of noise, the same noise as when I tested to play BF3. I suspect that it has something to do with the dedicated graphic card, AMD Radeon HD 7730M. Can the dedicated card be turned off?, I could not do it through the BIOS-settings, I could not find anything there.

    The computer has intel core i7-3612QM with integrated gpu intel-HD4000, 8 GB ram and a 256 GB samsung 830 ssd-drive.

    I appreciate all help I can get, and apologies for my not-so-good english. :)

    Thank you man, I should read that before starting a new t....

    Anyway, do you have any comments on the switchable graphics part?

    Should I take a look at the KMS-projekt here on FreeBSD? Or is there modules that can be unloaded from the kernel and in that way make a device inactive?

    Thanks

    I have the same laptop but it seems the wireless chip isn't supported yet (as of FreeBSD-9.1 RC2):

    Code:
    iwn0: <Intel Centrino Wireless-N 130> mem 0xc1500000-0xc1501fff irq 17 at device 0.0 on pci8
    iwn0: adapter type 12 not supported
    iwn0: could not attach device, error 45
    device_attach: iwn0 attach returned 45
    


    As you can see above, the chip is incorrectly detected. If you do # pciconf -lv you will probably get output like:

    Code:
    none2@pci0:8:0:0:       class=0x028000 card=0x44628086 chip=0x08878086 rev=0xc4 hdr=0x00
        vendor     = 'Intel Corporation'
        class      = network
    


    There is firmware available from Intel for the N-2230 but when I tried to modify the iwn(4) driver to use it I encountered kernel panics.

    For now I use a cheap, supported USB WiFi card!

    Also I can't get the card reader or ATI Radeon 7700M to work. Even the Intel HD 4000 graphics card is very slow but at least usable (just).

    I tried to turn off the ATI card using various loader.conf(5), device.hints(5) and loader(8) commands but the ACPI-based hardware discovery seems to override all that.

    I get the impression that support is 'nearly there'.

    I'm not good in the drivers under freebsd, but can it even than that might help.
    Intel Centrino Wireless-N 2230 - WiFi

    I think there's a similar problem discussed.
    But the decision seems to have not been found.

    There are at least some suggestions?

    This is an unacceptable solution.
    This is a crutch.
    This workaround.

    I want to do without the crutches.

    I already know about this crutch.

    Well, this is Intel! Really with Freebsd so bad that it even Intel device does not support?
    Or do I need to support Intel's talk and not here?

    This is a FreeBSD user to user forum. Not a helpdesk. Do some searching and reading yourself if you don't get any suggestions that please you from here.

    I got rid of that shit.

    No other OS except Microsoft 'windows' could be installed on that piece of shit because of the dual graphic thing. When I had Linux or FreeBSD running on it, the AMD GPU was always on, which generated a lot of noise and heat.

    Never buy AMD and Dell shit again.

    .. we do need more iwn maintainers

    Intel support the driver on Linux, but they don't have anyone actively doing FreeBSD development.

    Bernhard has done a great job fixing 11n support for the intel NICs, but he sadly doesn't have the time right now to work on the newer chipset support. So it hasn't appeared.

    So if someone wants to step up and port the necessary changes to the iwn driver to support the newer Intel chips, we'll all be very appreciative. That's the only way that you're going to get chipset support for the 2100/6300 and other recent chips.

    My problem is still relevant: post #6 in this thread.

    Any news?
