索尼Vaio Pro Duo 13 SDIO Broadcom BCM43241未获认可

Question

对于解决方案，请跳到本文的最下面。保持所有跟踪变化，为其他人寻找这一点。

我已经决定，由于原始员额不再更新，我将启动一个关于这个问题的新线程。这个问题还在继续，我还没有找到解决办法。

当在13上安装linux时，SDIO BCM43241无线设备是不被识别的。感谢kwoby对这个职位的评论，它不起作用的原因是it is normally is created using nvram-tools, but it does not work on the Sony Pro 13。

对于Sony 13，这个职位可能已经找到了答案。

在文章中，它链接到两个不同的文件：

后者，用户声称已经联系了来自Broadcom的开发人员，这是开发人员提供的文件。

这是用户的报价

在联系了broadcom的一位开发者之后，他给了我一封邮件，他和一个有同样问题但成功解决了这个问题的用户之间的邮件。用户通过发送另一个nvram和固件(一个桶和一个txt)帮助我，它工作了。我认为这仅仅是因为无线网卡对于当前内核来说太新了(如果我作为linux新手说错了什么的话，请纠正我)。

我尝试了brcmfmac-sdio.zip文件，它只对我起了部分作用。

在brcmfmac-sdio.zip之前：

dmesg：

在brcmfmac-sdio.zip之后：

dmesg：

您现在可以看到它在iwconfig中得到了认可：

root@chickenbutt:~# iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

我们可以看到，因为brcmfmac43241b4-sdio.txt文件现在存在，所以它能够完成brcmfmac模块的加载。但完全不起作用。例如，您不能将无线接口设置为monitor mode，也不能使用iw扫描路由器。

root@chickenbutt:~# ifconfig wlan0 down
root@chickenbutt:~# iwconfig wlan0 mode monitor
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Operation not supported.

如果您试图使用iw扫描网络，会发生这样的情况：

root@chickenbutt:~# iw wlan0 scan
scan aborted!

更新，无法连接扫描和连接到5 5GHz站：

驱动程序加载后，它似乎没有连接到5 5GHz的电台。然而，改变监管领域似乎有效。

在改变监管领域之前：

root@chickenbutt:~# iw reg get

解决方案：

1. 从上面的链接下载brcmfmac-sdio.zip
2. 将.txt文件复制到/lib/firmware/brcm/brcmfmac43241b4-sdio.txt
3. 重新启动
4. 运行命令iw reg set US

Answer 1

这是我所做的，工作得很好。请不要下载其他的.txt，它不能像你期望的那样工作(即2.4 GHz /5 GHz并且能够达到300 to /S) .You必须从您的NVRAM创建txt (步骤3)。

1. 确保您拥有/lib/固件/brcm/brcmfmac43241b4-sdio.bin
2. 如果尚未安装：“挂载-t efivarfs无sys/固件/efi/efivars”
3. cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 >/lib/固件/brcm/brcmfmac43241b4-sdio.txt
4. modprobe -r brcmfmac &&
5. 准备好了！

Answer 2

解决方案：

1. 从上面的链接下载brcmfmac-sdio.zip
2. 将.txt文件复制到/lib/firmware/brcm/brcmfmac43241b4-sdio.txt
3. 重新启动
4. 运行命令iw reg set US

现在，可能有一种方法可以永久地设置适配器管理域(在引导参数或配置中)，但现在可以这样做:D
