Hi,

I decided to write because I have any idea how to solve my problem.I have Broadcom BCM4311 WiFi card in my notebook so I did the following activities:

- I compiled kernel with options

I don't have a Broadcom but from your logs it seems you are possibly missing firmware for it. Also eix seems to imply that the following might be useful:

supposedly he has b43-firmware installed (he noted it above, sandwiched between the other stuff

)

I'd be more curious to see more from the build log on broadcom-sta

He included the parts mentioning "incorrect kernel settings", but he didn't post the part above that, which would say what symbols/options/whatever he's missing.

He has CONFIG_SSB and all that, else b43 wouldn't be available. Which makes me wonder if he has lib80211 enabled, as well, if he has to use WEXT, I think he'll need to emerge net-wireless/iw

I suppose the next obvious question - if that firmware blob/file exists in /lib/firmware at all, and if not, what the output of equery files b43-firmware shows

First of all disable all B4* and SSB:

There is a Gentoo wiki article for broadcom wlan. The broadcom-sta driver only compiles if the b43 kernel driver is disabled in the kernel configuration. You can find information (including a compatibility list) for the b43 kernel driver here.

Usefull information would be:

Hi.

Don't use wlan0 use eth1 instead. I made this mistake too.
After I used eth1 it works fine.

Thanks you for answer.

Could you explain me where is option CONFIG_WIRELESS_EXT. in kernel configuration?

when I search per / CONFIG_WIRELESS_EXT I get this

cach0rr0 · Posted: Sat Mar 05, 2011 11:28 pm Post subject:

not directly accessible through menuconfig. you have to select an option/symbol that selects it (really annoying!). Same deal as WEXT_PRIV that it mentions in the build message

Easiest is to enable "IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP)"

for broadcom sta you should:

-under networking support, enable wireless, enable cfg80211 (as a module), enable lib80211 (labeled 'Common routines for IEEE802.11 drivers'), disable 'mac80211' (labeled 'Generic IEEE 802.11 Networking Stack (mac80211)')
-under device drivers, network device support, wireless lan, about mid way down you should see the HOSTAP option I noted at the top of my post, enable that, it will select WIRELESS_EXT

that should get your broadcom-sta building and working

Thank you for answer. I did all this activities you ordered and [WOW

] Wicd Network Mangager show my WiFI named UPC020750! But now I have problem to connect to this wiresless network. It uses WPA2-PSK encryption key so I write my password - unfortunately each time I get information: unsuccessful connection: bad password! What is the problem? On my router is info that it works on channel 7 and WICD shows Channel 6 -whether it can cause some problem? And maybe problem causes bad WPA Supplicant driver - I use wext driver.

Have you any suggestions what else I can do to connect to my WiFi?

Regards and in advance great thanks for help!

Surprisingly I've an identical card -

0b:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

And it all works without the slightest issue. Just emerge nm-applet.

Hi,

Excuse me that so lately I paste my kernel config but recently I have little free time. My kernel configuration is here http://pastebin.com/uhJMvY9g. I pasted above also fragment my wicd logging informations- if you want more - tell me please what else I have to paste. I still hope that I will enjoy my WiFi in my notebook.

Regards and in advance great thanks for answer! :wink:

I have another problem with this driver(or with some configs).
I have installed gentoo-sources-2.26.37 and broadcom-sta-5.100.82.38
There are no errors appeared while I was compiling broadcom-sta.
But my card seems not to show itself
