Debian 中的 Broadcom wi-fi 卡驱动程序问题

我的笔记本电脑是 HP 250 G4 P5T98ES

我的操作系统是：Debian jessie 20160917

当我从 live-usb 安装 Debian 时，它告诉我它无法连接到无线网络，因为它没有非免费驱动程序。所以我决定稍后再安装驱动。我从 debian 站点下载了无线驱动程序（实际上，我下载了整个非免费固件包。然后我在终端中以 su 模式运行命令：

dpkg -i firmware-brcm80211_0.43_all.deb

输出表明它已成功安装（或类似的内容）。然后我跑了：

dpkg -l firmware-brcm80211

它给了我以下输出：

Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

我已经重新启动系统，但在网络设置中我仍然只看到两个选项：有线和网络代理。

添加此行后：

deb http://httpredir.debian.org/debian/ jessie main contrib non-free

到 /etc/apt/sources.list ， apt-get 更新失败：

我的 /etc/apt/sources.list 现在看起来像这样：

#

通过从包含固件的 live-cd 版本安装 debian 解决了问题。现在我有无线网络了。

答案1

您正在安装错误的司机为您的卡。

你有BCM43142 802.11b/g/n [14e4:4365]使用该wl模块的。

请阅读以下内容：Debian 官方文档。

您可以在哪里找到有关如何安装（正确的）驱动程序的信息：

将“非自由”组件添加到您的 Debian 版本的 /etc/apt/sources.list 中，例如：

# Debian 8 "Jessie" deb http://httpredir.debian.org/debian/ jessie main contrib non-free

更新可用包的列表。安装相关/最新的 linux-image、linux-headers 和 Broadcom-sta-dkms 软件包：

# apt-get update
# apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

这还将安装推荐的无线工具包。 DKMS 将为您的系统构建 wl 模块。

卸载冲突的模块：

# modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

加载wl模块：

# modprobe wl

答案2

wifiBCM43142在当前内核版本下有bug 3.16，你可以阅读@Stephen Kitt的评论Debian 错误报告从这里，我建议编译3.2.82版本，然后按照描述的步骤安装驱动程序这里。您还可以从向后移植的4.6版本安装新内核4.7。
