我的系统:
DELL Latitude E6400 上的 Fedora 24 64 位
我有一个 BCM4322 无线接口
lspci -vnn -d 14e4:
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)
Subsystem: Dell Wireless 1510 Wireless-N WLAN Mini-Card [1028:000d]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f69fc000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [40] Power Management version 3
Capabilities: [58] Vendor Specific Information: Len=78 <?>
Capabilities: [e8] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [d0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting

Capabilities: [16c] Power Budgeting <?>
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb, wl
我安装了 akmod-wl 并重新启动了系统。但无线接口仍然无法激活,因为模块似乎未签名:
$ lsmod | grep wl
wl 6447104 0
cfg80211 565248 1 wl
我在 dmesg 中看到这个:
[ 14.847359] wl: module license 'MIXED/Proprietary' taints kernel.
[ 14.847364] Disabling lock debugging due to kernel taint
[ 14.856059] wl: module verification failed: signature and/or required key missing - tainting kernel
我不知道如何解决这个问题?
答案1
您需要禁用安全启动。进入BIOS并找到该选项,禁用它并重新安装wl
答案2
我的系统:
- MacBookPro5,3 上的 Fedora 32 x86_64
- BCM4322 14e4:432b 无线接口
- 使用 rpmfusion 中的 akmod-wl
akmod-wl 提供 b43 和 wl 驱动程序。使用 b43 启动该卡,然后运行 wl。
删除并卸载冲突的驱动程序包:
dnf remove b43-openfwwf
启动时,仅加载 wl 驱动程序,但 BCM4322 未分配设备。
# lsmod | grep -e "wl\|b43"
wl 6471680 0
cfg80211 864256 1 wl
# lshw -C network -short
H/W path Device Class Description
==============================================================
/0/100/a enpXXXX network MCP79 Ethernet
/0/100/15/0 network BCM4322 802.11a/b/g/n
卸载正在运行的 wl 驱动程序。加载和卸载 b43 驱动程序。然后再次加载wl驱动程序。 (wl无法启动卡,但b43无法运行卡。)
/usr/sbin/modprobe -r wl
/usr/sbin/modprobe b43
/usr/sbin/modprobe -r b43
/usr/sbin/modprobe wl
BCM4322 现在应该分配有一个设备:
# lshw -C network -short
H/W path Device Class Description
==============================================================
/0/100/a enpXXXX network MCP79 Ethernet
/0/100/15/0 wlpXXX network BCM4322 802.11a/b/g/n Wireless LAN Controller
SSID 现在应该可用,您可以从 NetworkManager 连接到:
# nmcli dev wifi list
IN-USE BSSID SSID MODE CHAN RATE SIGNAL BARS SECURITY

将上面的 modprobe 命令放入 /usr/local/bin/wifi_drivers.sh 的脚本中,您可以创建一个服务来在 wpa_supplicant 之前运行该脚本:
