I've been using the broadcom-sta driver successfully. But I saw in this page that the b43 driver is now available for my board.

Here is my lspci:
Code:

lspci -vnn | grep 14e4
03:00.0 Network controller [0280]: Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)


I've enable b43, according to http://en.gentoo-wiki.com/wiki/Broadcom_43xx

The computer boots ok, if I compile b43 I can load it successfully, but no interface is available with ifconfig, iw list, iwconfig neither with cat /proc/net/dev

any tips?

Did you install the firmware? What does dmesg say?

Well, I think I've installed the firmware. I've download the fwcutter 015 and installed the 5.10.56.27.3 broadcom firmware, It doesn't work, so I've download the 5.100.138 broadcom firmware too. All the files were extracted to /lib/firmware.

The only think I've found in the dmesg about the board is:
Code:

[    0.504061] pci 0000:03:00.0: [14e4:4357] type 0 class 0x000280


When I load the driver (modprob b43) I get the following message in the dmesg.
Code:

[  276.857023] cfg80211: Calling CRDA to update world regulatory domain
[  276.860208] Broadcom 43xx driver loaded [ Features: PMNL, Firmware-ID: FW13 ]


The complete dmesg is in: http://pastie.org/2712414

Using the firmware from 5.100.138 is definitely wrong. It's for kernels starting with 3.2. The right one to use for 3.1 is 5.10.56.27.3. "It doesn't work" doesn't really say anything.

dmesg is weird, there should be way more regarding b43 in there. Do you have any other driver installed that might conflict? All three (wl, brcmsmac, b43) support this device. Hmm, did you also activate bcma in your kernel? You need it for this card.

Update bellow

I erase my /lib/firmware/b43 folder, and the extracted the 5.10.57.27.3 again, now I'm using just it.

Well, I have wl but with kernel 3.0, so I don't think it will cause any conflict, am I right? I've tried brcmsmac, bit it is now disabled (in fact all staging drivers are).

I think the problem was the bcma that wasn't enabled. Can't the kernel raise an error when the b43 is detected without the bcma, or bcma is needed only for this card?

Now I get the card, as we can see in the iw list command, but I think it is detected as an 802.11g and not as 802.11n as it should be (I think).

So I can't use the card yet. I've pasted my dmesg and my kernel .config in:
http://www.laps.ufpa.br/pedrobatista/dmesg
http://www.laps.ufpa.br/pedrobatista/.config

Any other tips?

Thanks in advance Gusar

The problem of being disconnecting and not associating with WPA2 was because I was using the option "Force usage of PIO instead of DMA".

The problem I've now is the 802.11g instead of 802.11n.

The other think I've observed is that when I was using the wl module (in kernel 3.0) I saw in my router that the signal was 90-99% to my PC (I'm just on the side of the router) now it's just 25-35%. And of course it was 802.11n now the router show it's connected as 802.11g.

Gusar, I've some knowledge in programming, so I think I can help in the development of the drivers (if it's needed), do you know anywhere I can start to make the driver more compatible?

bcma is needed for this card and around three others. Basically those that are supported by brcmsmac. Previous Broadcom cards used ssb instead of bcma, that's why b43 doesn't insist on having bcma there. As for N, b43 doesn't yet support 5GHz and 40MHz channels. If your router is set to that, set it to 2.4GHz and a 20MHz channel. If that won't work, brcmsmac might be a better option for now.

If you want to help development of b43, the mailing list would probably be the best place to ask about what you could do: http://lists.infradead.org/mailman/listinfo/b43-dev. Then there's the general wireless list: http://vger.kernel.org/vger-lists.html#linux-wireless

Thanks Gusar.

I think the signal is now pretty week, not only in home, but in all environments (in my classroom I couldn't get a signal), but I assume that is because it isn't fully operation yet (it work with wl).

I'll take a look and try to help in the lists, thanks again!
