我已经安装了 CENTOS 6.3。我的机器是戴尔工作室。我有以下无线 Broadcom 型号。

[root@treasure hybrid_wl]# lspci | grep -i wireless
03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

我从http://www.broadcom.com/support/802.11/linux_sta.php获得了这个驱动程序的源代码。

我的机器内核是

[root@treasure hybrid_wl]# uname -r
2.6.32-358.18.1.el6.x86_64

从http://www.broadcom.com/support/802.11/linux_sta.php构建软件包时。我收到以下错误。

我该如何解决这个问题？我错过了什么？我还更新了 Broadcom 支持组的电子邮件 ID，此处为 linux-wlan-client-support-list@broadcom.com。Broadcom 是一家领先的公司，我希望他们能在这里提供帮助。我也给他们发了电子邮件。Broadcom 只能在这里分享他们的解决方案，让全世界都能从中受益。

对于 Broadcom，我已将其发布在堆栈溢出上，因为每个人都可以从中受益。目前，我无法在笔记本电脑上使用 WIFI。我被有线连接卡住了。请帮助我，以便我可以让 WIFI 正常工作。当什么都没有构建时，我在最新版本中尝试了以下操作。

make API=WEXT (deprecated) ----> 我正在关注自述文件。

这会检测到可用的 wifi 网络，但无法连接到 AP。看起来这需要无线扩展工具。

做，我需要为它安装任何东西。还是说，不要使用已弃用的构建规则，而是修复构建错误？你对此有何建议？

建议，我可以跟进。

关键在这里：/home/joshis1/hybrid_wl/src/wl/sys/wl_cfg80211_hybrid.c:2122：错误：函数“cfg80211_roamed”的参数太少</p>

如果你检查 wl_cfg80211_hybrid.c ~line 2122

cfg80211_roamed(ndev,
#if LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 39)
                    NULL,
#endif
    (u8 *)&wl->bssid,  conn_info->req_ie, conn_info->req_ie_len,
    conn_info->resp_ie, conn_info->resp_ie_len,        GFP_KERNEL);
    WL_DBG(("roaming result\n"));
}

虽然我正在运行 RHEL6.5 和 2.6.32，但它运行的 net/cfg80211.h 版本需要额外的参数，所以我需要将行更改为： #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 32)- 或者完全删除 if/endif。不幸的是，它并不止于此，如果 wl_cfg80211_hybrid.c 中有十几个 KERNEL_VERSION 需要更改。

一旦完成（您可以测试但运行'make'并返回并修复错误）它确实可以编译和安装。正如预期的那样，我现在正在使用 WPA 等运行它。似乎只是 RedHat 将一些 cfg80211 从更新的内核引入到 2.6.32 中，从而混淆了模块。

上周我在朋友的 CentOS 6.4 Acer 笔记本电脑（BCM 43227 WiFi）上遇到了完全相同的问题。Broadcom 驱动程序只能使用 API=WEXT 选项构建（否则，与您引用的错误消息相同），但它仅适用于“开放”WiFi 网络，而不适用于 WPA/WPA2（不了解 WEP）。在 /var/log/wpa_supplicant.log 中，我association request to the driver failed在尝试连接到 WPA 网络时收到错误消息，而 NetworkManager 只会不断询问密码。

除了直接编译 Broadcom 驱动程序外，我还尝试按照ELRepo wl-kmod Howto（通过CentOS wiki）的建议构建 RPM 包，但同样失败了（Broadcom 文件名与预期的 RPM 不同）。

这个周末我再次查看了计算机，并意识到 ELRepo Howto 中链接的 RPM 文件已更改，并且文档本身已于 9 月 26 日更新。所以我再次尝试使用较新的 RPM，完全按照说明进行操作，这次成功了。得到一个安装 wl.ko 内核模块的 RPM 文件。通过 加载它modprobe wl，之后 NetworkManager 找到我的 WPA2 wifi 并在第一次尝试时连接。
