I install an old wifi card (BCM43142 14e4:4727) on my device, and no Wi-Fi network can be detected.

After lspci -k | grep -iA3 network

root@Tower:~# lspci -k | grep -iA3 network

04:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)

Subsystem: Hewlett-Packard Company Device 804a

Kernel driver in use: bcma-pci-bridge

Kernel modules: bcma

I think we should use brcmsmac instead of bcma-pci-bridge.

so I add Modprobe.d config file in tools, system drivers:

brcmsmac; state Custom; options brcmsmac ids=14e4:4727.

bcma; state Disabled; blacklist bcma, blacklist bcma-pci-bridge.

add "modprobe brcmsmac" in /boot/config/go

but still not working,

After lspci -k | grep -iA3 network

.....

Please post the diagnostics without any go file modification, to see what the initial issue is.

From what I can find, that adapter is not supported by the in-tree Linux driver, it requires an out-of-tree driver, which is closed source. I recommend getting an adapter from this list instead: https://github.com/morrownr/USB-WiFi/blob/main/home/USB_WiFi_Adapters_that_are_supported_with_Linux_in-kernel_drivers.md

I found these websites (https://wireless.docs.kernel.org/en/latest/en/users/drivers/brcm80211.html,https://wiki.archlinux.org.cn/title/Broadcom_wireless) say brcmsmac is opensource, and unraid tools --> system drivers include brcmsmac.

And my wireless network card is connected via PCIe rather than USB. Is the website you shared a list of all wireless network adapters supported by Unraid? Is there a list of supported PCIe network adapters?

From what I found, it needs this proprietary driver: https://wiki.debian.org/wl

Nope, not all.

Not that I'm aware of.

I think both wl and brcmsmac work on BCM4313.

Linux is detecting a BCM43142, not 4313

sorry, my bad
