问题描述如下
我笔记本的wifi网卡识别不了,不知道为什么?? 使用ifconfig -a 只列出了有线网卡以及外接的无线网卡如下 enp4s0f1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether 38:2c:4a:32:3e:b9 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 40 bytes 2000 (1.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 40 bytes 2000 (1.9 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlp0s20u1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.229 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::2e0:4cff:fe9d:d82d prefixlen 64 scopeid 0x20<link> ether 00:e0:4c:9d:d8:2d txqueuelen 1000 (Ethernet) RX packets 158237 bytes 143296898 (136.6 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 157438 bytes 27402578 (26.1 MiB) 笔记本自带的无线玩卡找不到 使用lspci则可以看到笔记本自带的无线网卡如下 03:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) 04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5287 (rev 01) 04:00.1 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 12) 这个就是啦03:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) 我按照wiki来 https://wiki.archlinux.org/index.php/Ne … 5.E5.8F.A3 他说lspci -v 执行后找到我的bcm网卡的相关信息如下 03:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) Subsystem: Lite-On Communications Inc Device 6605 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f7900000 (64-bit, non-prefetchable) [size=32K] Capabilities: <access denied> Kernel driver in use: bcma-pci-bridge Kernel modules: bcma 然后他说接下来, 用 dmesg | grep module_name 来检查是否已经加载了驱动 我不知道bcma-pci-bridge bcma这两个哪一个是module_name ,于是我两个都尝试了如下 dmesg | grep bcma-pci-bridge 什么都没有 dmesg | grep bcma 如下 [ 5.908662] bcma: bus0: Found chip with id 43142, rev 0x01 and package 0x08 [ 5.908690] bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x28, class 0x0) [ 5.908712] bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x21, class 0x0) [ 5.908755] bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x16, class 0x0) [ 5.908807] bcma: bus0: Core 3 found: UNKNOWN (manuf 0x43B, id 0x368, rev 0x00, class 0x0) [ 5.922433] bcma: bus0: Bus registered 之后他说 加载设备模块 用 Google 查找芯片组需要的模块/驱动。常见的驱动模块有用于 Realtek 芯片组网卡的 8139too,或者用于 Sis 芯片组网卡的 sis900。知道要使用什么模块之后,尝试 手动加载它。如果你碰到了未找到模块的错误,可能驱动没有包括在 Arch 的内核中。你可以在 AUR 中搜索模块名称。 到这一步我就不明白了,我该如何知道我的网卡是什么芯片组呢?我有该如何查找芯片组需要的模块呢??
问题解决
需要这个包: broadcom-wl-dkms archlinuxcn和AUR里面都有 装完重启即可,如果wl模块没有被自动加载的话,手动敲一下: modprobe wl Archwiki参考页面: https://wiki.archlinux.org/index.php/Broadcom_wireless
