标签： linux centos centos6 broadcom

我安装了CENTOS 6.3。我的机器是戴尔Studio。我有以下无线广播模型。

[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获得了此驱动程序的源代码。

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？我也更新了Broadcom支持组的电子邮件ID，这里是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，以便世界可以从中获益。

致Broadcom， 我已经在堆栈溢出上发布了这个，因为每个人都可以获得它的优势。目前，我无法在笔记本电脑上使用WIFI。我坚持使用有线连接。请帮助我，以便我可以让WIFI正常工作。当什么都没有建成时，我尝试了以下最新版本。

make API = WEXT（不建议使用）----＆gt;我正在关注自述文件。

这会检测可用的wifi网络，但无法连接到AP。看起来这需要无线扩展工具。

我需要为它安装任何东西。或者您说，不要使用已弃用的构建规则，而是修复构建错误？你的建议是什么？

建议，我可以继续。

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

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，但它正在运行net / cfg80211.h的版本，它需要额外的参数，所以我需要将行更改为： #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 32) - 或者只是完全删除if / endif。不幸的是它并没有就此止步，如果在wl_cfg80211_hybrid.c中需要更改，那就是十几个KERNEL_VERSION。

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。看起来只是RedHat将一些cfg80211从更新的内核引入2.6.32，这会让模块感到困惑。

答案 1 :(得分：1)

我上周在朋友的CentOS 6.4 Acer笔记本电脑（BCM 43227 WiFi）上遇到了同样的问题。 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），但它只适用于＆＃34; open＆＃34; WiFi网络，而不是WPA / WPA2（不了解WEP）。在/var/log/wpa_supplicant.log中，当我尝试连接到WPA网络时，我收到错误消息association request to the driver failed，而NetworkManager只是一直要求输入密码。

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

本周末我再次查看了计算机，发现ELRepo Howto中链接的RPM文件已经更改，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，完全遵循instructions，这次它起作用了。有一个安装wl.ko内核模块的RPM文件。通过modprobe wl加载它，之后NetworkManager发现我的WPA2 wifi并在第一次尝试连接。
