    By the way /usr/lib/pm-utils/defaults undid my edits by itself.
    curious... on my system it's really stable so far, are you on lucid or maverick? 32 or 64 ?

    Thanks for the work.
    BCM4313 ,as stated above, is working for me too. Both RFMON and Injection seems working, but the injection seems pretty alpha-quality ! Low rates and low success for injected packets, even for close AP.

    Anybody else having the same problem on injection?

    my test bed: Ubuntu 10.10 2.6.35-22 64bit.

    Axx83, I'm running kubuntu 10.10 with the 2.6.34-020634-generic kernel (to prevent a problem with system freezes on battery power), on a quad-core Intel studio 1558. Ndiswrapper was a bust. I'm back on the latest wl driver, which doesn't seem to want to get me to 802.11n speeds despite my n hardware.

    Oh, by the way, 64-bit version.

    The linux wireless wiki says that this driver is unstable for my card (43224) unless I restrict the kernel to one cpu. I'll wait for a bit, I guess.

    the linux wireless wiki is outdated, on my 43225 the driver is very stable

    I know the kernel team has been making changes to the brcm80211 driver, so maybe I'll try the latest version. The Broadcom STA proprietary driver (wl.ko) has been extremely slow (never connects over 53 MBits/sec, and often drops to 14 or even 2 MBits/sec, despite being 10 feet away from my router in the same room).

    OK, installed the brcm80211 driver per the instructions - still somewhat unstable but maybe better? According to the readme, it's still unstable with the 43224 chip and multicore processors (my situation). Had a kernel panic in wlc_phy_n.c on line 19709 on one bootup. Where's a good place to feed this info to the devs?

    Maybe that's the problem, I have 43225 and had no kernel panic, no connection drops, only a few sporadic issues with suspension and back, the networkmanager's list on networks was empty and only removing and inserting back the module did the trick.

    I wrote the developers about this and this was their answer:

    We do not currently have a list specific to the brcm80211 driver. Patches and discussion are posted to devel@linuxdriverproject.org and
    linux-wireless@vger.kernel.org.
    See http://driverdev.linuxdriverproject....listinfo/devel
    and http://linuxwireless.org/en/develope...s_mailing_list
    for information on these two lists.
