[Solved] No wireless extensions BCM4352 Broadcom adapter

[Solved]

Hi, first post here.

I have recently installed ArchLinux, and I cannot yet understand why I can't see any WiFi connections. Ethernet works fine. I've verified that my NetworkManager.service and wpa_supplicant.services are running, yet I get these results from the following commands:

$ ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 10:c3:7b:92:24:24 brd ff:ff:ff:ff:ff:ff
    altname enp0s25

$ iwconfig

lo        no wireless extensions.

eno1      no wireless extensions.

$ iwlist scan

lo        Interface doesn't support scanning.

eno1      Interface doesn't support scanning.

$ lspci -vnn -d 14e4:

05:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)
    Subsystem: ASUSTeK Computer Inc. Device [1043:855c]
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at df400000 (64-bit, non-prefetchable) [size=32K]
    Memory at df200000 (64-bit, non-prefetchable) [size=2M]
    Capabilities: <access denied>
    Kernel driver in use: bcma-pci-bridge
    Kernel modules: bcma

I suspect that i'm possibly using the wrong driver for my wireless device, which is built into my Z97 Pro-WiFi Mobo. I'm not sure that there IS a driver for my device though as all driver lists that I've flipped through do not show explicit support for 4352. I'm wondering if I will need to buy an additional WiFi PCI device that is supported in order to use WiFi.

When running dmesg I do see an error in these lines:

[   11.497282] b43-phy0: Broadcom 4352 WLAN found (core revision 42)
[   11.497632] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)
[   11.497638] b43: probe of bcma0:1 failed with error -95
[   11.497648] Broadcom 43xx driver loaded [ Features: PNLS ]

I'm looking through the wiki quite frantically as this is driving me nuts.

BCM4352 (14e4:43b1) is listed under https://wiki.debian.org/wl#Supported_Devices
So the right driver to install would be broadcom-wl

Did it work on the install ISO? You probably want to install  the properietary variant with https://archlinux.org/packages/?name=broadcom-wl-dkms and make sure you have linux-headers for your intended to be used kernel installed.

Only lan worked during and after the ISO install. Wireless capability was not detected when I checked for internet connections prior to the install.

I’ll try installing this today and see how it goes. I’m still learning how to effectively search the arch repositories, so thanks for the link.

Installing that package gave me a lot of more functionality with my network. I can actually detect wireless connections now. First attempt to make a connection failed, but I think I can figure it out from here.

Thanks!

Hi I am facing a similar issue. I have Asus Rog G750JS and it has Broadcom BCM4352 (14e4:43b1 rev3). I am trying to install Arch on it using the iso. is it possible to install the drivers after booting into the iso image and get wifi working ?

The wl driver is supposed to be on the install iso, BigDave76 just didn't add it when installing the system.
