Broadcom BCM4310 USB Controller (Wifi)

[Matthias Apitz]

Hello,

I have a new laptop Acer Aspire One D250 and pulled out HEAD from SVN
today morning. As far as I can see in sys/dev/bwi and sys/dev/bwn the
above chip is still not supported. I am wrong?

Any other idea how to get Wifi working on this mini laptop?

Thanks in advance

matthias

i have the same problem with a BCM43225. there is a linux driver: is
anyone going to port it in the near future? would a donation help the
process?

i'm on i386 at the moment, but i'll switch to amd64 as soon as i
decide what to do (keep freebsd natively or virtualize it under
windows... it depends on the wireless driver). would that change
anything?

here's my experience. also, as a reference, here's what i get if i add
the device id to siba_bwn:
# kldload if_bwn
siba_bwn0: <Broadcom BCM43225 802.11b/g/n Wireless> mem
0xda100000-0xda103fff irq 16 at device 0.0 on pci2
siba_bwn0: cannot map register space
device_attach: siba_bwn0 attach returned 6
and here is the new open source driver:
http://wireless.kernel.org/en/users/Drivers/brcm80211

and now, ndis. the driver is bcmwl6
(http://people.freebsd.org/~avilla/bcmwl6.inf and
http://people.freebsd.org/~avilla/bcmwl6.sys , apparently no need for
firmware files, but i'm not sure), which is said not to work with ndis
on linux forums (maybe they removed the support for winxp)
matthias: you should try bcmwl5, that could work for you

using the unmodified files i've attached (they default to winvista and
win7) i get this:
# kldload ./bcmwl6_sys.ko
module ndis already present!

which should mean that the driver doesn't support xp. so i tried
changing (in the .inf)
%V_BCM% = BROADCOM, NTx86.6.0, NTamd64.6.0, NTx86.6.1, NTamd64.6.1
to
%V_BCM% = BROADCOM, NTx86, NTamd64
and then i only get "module ndis already present!", but no interface shows up

i also tried removing NTx86, making it
%V_BCM% = BROADCOM, NTamd64
(it should be correct), and with this modification i get the same
error messages of the first attempt

anyway i don't have any experience with ndis... should i test anything else?

so, i've tried the ndis driver with amd64 and it paniced, as you said.
do you have any idea on when you're gonna fix this? i need to know if
i can keep amd64 and wait for a fix (in short time) or if i have to
install i386 temporarily...

thanks

thanks!
i've applied a checkout of last night to current. i can load the
module after boot, but the panic is still there when i unload or load
on boot, and wpa_supplicant fails to work (see attached log)

consider me as the third one :)

CURRENT.

ok. unfortunately in this test i made an error and just saw that...
`--> git status
# On branch ndis5
# Your branch is ahead of 'origin/ndis5' by 13 commits.
i hope it's ok for this time

i did it, and here you are the results:
