Hello all,
I've been struggling to get the broadcom 4312 wlan chip to work on a hp2133
laptop. According to all documentation I found this should work and it almost
does: Could extract firmware and driver is loading but network manager in Fedora
only shows "device not ready" (but I can use to wireless switch to toggle to
"deactivated"). Now I'm out of ideas and hope anybody can help. Details enclosed
below

HISTORY
hardware is hp 2133 laptop
wlan is enabled in bios
distro is fedora 25
yum install broadcom-wl
yum install akmod-wl
yum install kmod-wl
yum install b43-fwcutter
yum install wget
used wget to download broadcom-wl-4.178.10.4.tar.bz2
wget http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2
used fw-cutter to extract firmware from wl_apsta.o to /lib/firmware
b43-fwcutter -w /lib/firmware wl_apsta.o
used wget to download broadcom-wl-5.100.138.tar.bz2
wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
used fw-cutter to extract firmware from wl_apsta.o to /lib/firmware
b43-fwcutter -w /lib/firmware wl_apsta.o
added modules to /etc/modprobe.d/blacklist as per resource #1
according to resource #3 b43 should be the correct driver and is loaded
lspci -nn -d 14e4:
according to resource #0 b43 should support 14e4:4315 (bcm4312)
made backups of firmware directories and freshly created above versions
created symlink to point to active version
only b43 directory affected by extraction
ls -ld /lib/firmware/b*
STATUS
using b43 driver and firmware 4.178.x
network manager shows up during boot
blue led is on but device is not ready
wireless switch is responsive (can toggle between not ready and deactivated)
using b43 driver and firmware 5.100.x

Thanks in advance and happy easter holidays!
BTW: I could also not compile the proprietary driver, but that's another issue.
I would really prefer to go with b43
Why are you blacklisting b43?
The only other things I see are as follows:
This line from the dmesg output looks strange.
[ 53.905515] b43-phy0 ERROR: PHY init: Channel switch to default failed
The rev ff in the lspci line is also strange. My BCM4312 shows rev 01.
02:00.0 Network controller [0280]: Broadcom Limited BCM4312 802.11b/g LP-PHY
[14e4:4315] (rev ff)
My BCM4312 device is in a 32-bit netbook that I seldom run. It will take a
couple of days to get its kernel updated to the current version so that I can
test the latest b43 code. I will report those results ASAP.
