升级到内核 5.19.0.32 后，BCM4313 Wi-Fi 无法工作

问题与此相同：

RTL8821CE 从 5.15.0-60 升级到 5.19.0-32 后 wifi 失效

lspci
07:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTL8411 PCI Express Card Reader (rev 01)
07:00.2 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0a)
08:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter (rev 01)

我被建议安装 Broadcom 驱动程序，我使用

sudo apt install firmware-b43-installer

驱动程序现在显示在软件和更新中，但重启后我仍然看不到 WiFi 选项。

在此处输入图片描述

答案1

BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)需要b43带有的内核模块firmware-b43-installer。

您安装了错误的驱动程序，导致正确的驱动程序被列入黑名单。

您可以在 GUI 中选择“不使用该设备”，也可以运行

sudo apt purge bcmwl-kernel-source
sudo modprobe b43

使设备工作。
