    I don't know if it help, but i remember, that a few months ago i tried to allow the STA broadcom driver and it works. Then i maybe do some changes, but don't know what changes. now i am having the same problem. If someone will be able to solve that problem, please answer or write me an e-mail. Thank you, everyone.



    This thread was about that specific card (the low power version of the BCM4312 (14e4:4315) with complete directions in post 7.

    Re: Broadcom BCM4312 802.11b/g (rev 01) - I've tried everything!

    I have an HP 6375s laptop. So I finally got mine working after getting to the stage of having b43 driver activated, but it would not detect any networks. This link got me this far: https://help.ubuntu.com/community/Wi...Driver/bcm43xx. Possibly I could have edited the network connections and added my wireless network manually. A shame that I did not know that a SSID is simply the name of the network and that's all that you need to configure. Anyway, I gave up on the b43 driver and activated the Broadcom STA driver instead. After a restart there was no change - no wireless networks detected. I then removed the wired ethernet connection and restarted. This time the Wireless card started correctly (the Wireless light went from orange to blue just before the log-in screen indicating its on) and detected the local networks.

    Now that its working I thought it might be useful to see a set of correct configurations:

    Hi icc97,

    Since you've got a working Broadcom 4312 WiFi using the STA driver, the scientist/"tester" in me would like you to run a few experiments- if you're willing.

    1. Restart the computer about 5 times (complete power down- maybe even unplug it) and see if the STA 4312 wireless still works (each restart). If you've got a dual/multiple boot system- maybe mix booting into Windoze/etc. a couple of times mixed in with those 5 shutdowns.

    2. With the 4312 WiFi running under Ubuntu- plug that ethernet cable back in and then run some diagnostics on the ethernet connection, and then see if the WiFi still works.

    2.A. Maybe [physically] switch off the WiFi and see if the ethernet still works.

    2.B. Switch the WiFi back on and see if the wireless will connect.

    2.C. Leave the ethernet cable plugged in and restart the computer and see if you can get a wireless connection after the restart.

    I've got a "method behind the madness" above- but I would rather get the honest impressions of the posters here on this thread to see what they think the problem is (before I reveal my current hypothesis- that is related to those diagnostic steps above).

    If you'd rather not experiment with your working 4312 WiFi connection- that's cool with me too- it IS YOUR computer after all, icc97.

    P.S. My HP DV-98xx laptop works "breasts" with that STA driver and my Broadcom 4321AG (but lspci reports that as a 4328 ). I have yet to see a cable that my NVIDIA nForce ethernet will not connect to "out of the box"- going back several years, and dozens of versions of Linux, too.

    I have same laptop. First of all, I tried to use aircrack-ng. FAILED! Now, could anyone send me step by step solution for installing driver and how to make bcm4322 work with aircrack-ng.

    I don't believe (but i could be wrong, often am) that the STA driver is compatible with aircrack-ng only the b43. See below:
