我已经决定原始帖子不再更新，我将就此问题开一个新帖子。此问题仍在继续，我尚未找到解决方案。
在 Sony Vaio Pro Duo 13 上安装 Linux 时，无法识别 SDIO Broadcom BCM43241 无线设备。感谢科沃比从他的评论这个帖子，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。
对于索尼 Vaio Pro Duo 13这个帖子也许已经找到了答案。
该帖子链接到两个不同的文件：

后者，该用户声称已经联系了博通的一名开发人员，并且这是开发人员提供的文件。
以下是该用户的引言
联系了 Broadcom 的一位开发人员后，他给我发了一封他和一位遇到同样问题但已成功解决该问题的用户之间的邮件。该用户通过发送另一个 nvram 和固件（一个 bin 和一个 txt）帮助我，它成功了。我认为这只是因为无线网卡对于当前内核来说太新了（作为 Linux 新手，如果我说错了，请纠正我）。
我尝试了这个brcmfmac-sdio.zip文件，但它只对我有部分作用。
前brcmfmac-sdio.zip：
dmesg：

你可以看到它iwconfig现在已被识别：
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，由于文件brcmfmac43241b4-sdio.txt现在存在，所以它能够完成brcmfmac模块的加载。但它不能完全工作。例如，您无法将无线接口设置为monitor mode，也无法使用它iw来扫描路由器。
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.
如果您尝试使用iw扫描网络，则会发生以下情况：
root@chickenbutt:~# iw wlan0 scan
scan aborted!

更新，无法连接扫描并连接到 5GHz 站：
驱动程序加载后，似乎无法连接到 5GHz 站。但是，更改监管域似乎有效。
更改监管范围之前：
root@chickenbutt:~# iw reg get

解决方案：
brcmfmac-sdio.zip从上面的链接下载- 将 .txt 文件复制到
/lib/firmware/brcm/brcmfmac43241b4-sdio.txt - 重启
- 运行命令
iw reg set US
答案1
这是我所做的，效果非常好。请不要下载其他 .txt 文件，它不会像您预期的那样工作（意味着 2.4 GHz / 5 GHz 并且能够达到 300Mb/s）。您必须从 NVRAM 创建 txt 文件（步骤 3）。
- 确保您有 /lib/firmware/brcm/brcmfmac43241b4-sdio.bin
- 如果尚未安装：“mount -t efivarfs none sys/firmware/efi/efivars”
- 猫/sys/固件/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113>/lib/firmware/brcm/brcmfmac43241b4-sdio.txt
- modprobe -r brcmfmac && modprobe brcmfmac
- 准备好！！

现在，可能有一种方法可以永久设置适配器监管域（在启动参数或配置中），但目前这样就可以了：D
