Raspberry Pi 3 B+ Wifi NIC not found


I installed my Raspberry Pi 3 B+ using the sarpi3-installer_slack14.2_30Mar18_sp1.img.xz image. I did a ftp network installation using ftp.slackware.org.uk. It boots up just fine and the ethernet port works. As I've said in another thread, I plan to use this Pi as a replacement for my wireless router.

I could use the rpi-update script, but would prefer not to. I prefer to run the 14.2 image instead of -current. It looks like the onboard wireless NIC is not recognized and no kernel module is loaded.
Code:
# iwconfig && lsusb && lsusb -t
lo        no wireless extensions.

eth1      no wireless extensions.

I ended up downloading the Raspbian brcm80211 firmware, extracted the .deb using ar, and used scp to copy it to my 3 B+, and ran modprobe to load it.

Download the Raspbian package.
Code:
$ mkdir -p ~/Downloads/rpi3_wifi_firmware
$ cd ~/Downloads/rpi3_wifi_firmware
$ wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb
Extract the package, and extract data.tar.xz. data.tar.xz has the firmware in it.
Code:
$ ar x firmware-brcm80211_20161130-3+rpt3_all.deb
$ tar xvf data.tar.xz 
./
./lib/
./lib/firmware/
./lib/firmware/brcm/
..snip..
./lib/firmware/brcm/brcmfmac43455-sdio.bin
./lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
./lib/firmware/brcm/brcmfmac43455-sdio.txt
..snip..
Copied the firmware to my Pi.
Code:
$ cd lib/firmware/brcm/
$ scp brcmfmac43455-sdio.txt pi@rpi3s:~/
$ scp brcmfmac43455-sdio.bin  pi@rpi3s:~/
$ scp brcmfmac43455-sdio.clm_blob rpi3s:~/
On the Pi 3 B+ I then copied the files to where they belong and loaded the driver.
Code:
# cd /lib/firmware/brcm
# cp /home/pi/brcmfmac43455-sdio.txt .
# cp /home/pi/brcmfmac43455-sdio.bin .
# cp /home/pi/brcmfmac43455-sdio.clm_blob .
Code:
# rmmod brcmfmac
# # modprobe -vvv brcmfmac
modprobe: INFO: custom logging function 0x1905c registered
insmod /lib/modules/4.14.31-v7-arm/kernel/drivers/net/wireless/broadcom/brcm80211/brcmfmac/brcmfmac.ko 
modprobe: INFO: context 0x254178 released
Now I have wifi.
Code:
# iwconfig
wlan0     IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

WIFI on a Raspberry PI 3 model B+

Thank-you for your detailed post. I followed it and now have WIFI working on a new PI 3 b+ install.

I had started out with wlan0 not found also. FWIW, I have kernel 4.19.34 installed on current.

Issues with the Broadcom wireless firmware going AWOL have been known for a while.

https://www.raspberrypi.org/forums/v...c.php?t=225906

With the RPis recent move to the 4.19.x kernel some users have had issues with wireless not working.

The "error -2" is a file-not-found error, it can't find brcmfmac43455-sdio.txt.

The kernel-firmware package has a brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt file. I symlinked brcm43455-sdio.txt to this and it appears to work. I don't know if there's a better or more-approved way to load this file.

Code:
[    4.561507] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
[    4.832063] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
[    4.843507] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available

The version in kernel-firmware is really old (Mar 1 2015, licensing issues preventing it from being updated) and doesn't provide the .clm_blob file, but loading it like this might work in a pinch.

Lightbulb work-around for the missing RPi3 & 4 wireless firmware

In order to address this issue...

SARPi now includes the new brcmfmac43430 and brcmfmac43455 wireless device firmware via the 'sarpi-hacks' packages for the Raspberry Pi 3 and 4. This package can be upgraded over any existing package but be aware it may change some of your config settings. Please see the sarpi-hacks.README (included) file before installing it: http://sarpi.fatdog.eu/files/extra/sarpi-hacks.README

The installation of the new firmware in this package relies on the old firmware being present. If you find that you're still missing the new firmware after installing the sarpi-hacks packages, run the following command and remove/install it again:

Code:
~# touch /lib/firmware/brcm/brcmfmac43430a0-sdio.bin
Until MoZes decides to include the new [RPi] Broadcom 43430 and 43455 wireless device firmware in Slackware ARM [and there's no valid reason(s) why he should], the above is how you can install it easily. This only applies to sarpi-hacks packages for the Raspberry Pi 3 and 4.

[EDIT] SARPi images and packages available from here: http://sarpi.fatdog.eu/index.php?p=downloads

Hi,

I have a Raspberry Pi 4 Model B Rev 1.1 board with fresh install of Slackware ARM -current.
I upgraded the kernel using raspi-update to version 4.19.60-v7l+
Currently I have no Bluetooth and WLAN interfaces after boot, even though I installed sarpi4-hacks.

I will look into this. It might not be soon [today] though. I'm very busy right now but as time permits I'll get back to you.

[EDIT]

I still haven't had time to look into this. My guess is; it's either going to be missing firmware or drivers that's causing the problem. Of which, you can 'borrow' from Raspbian if you're struggling to find them.

I can't remember off the top of my head which BT drivers the RPi4 uses. However, you can just copy those over the same as you did with the wireless shizzle.

Well, I copied over all the files and folders from underneath /lib/firmware from Raspbian to Sarpi, and did a reboot on both my PI 3B+ and PI 4, but no Bluetooth on either of them.

Regarding the WLAN firmware question I stand a bit puzzled. I see no additional files being added in relation to brcmfmac43455, but the adapter seems to work with the following content of /lib/firmware/brcm (the files copied from Raspbian -- you can compare it to the file list from my previous post):

On top of this, I am getting the following on by PI 3B+ with the firmware from Raspbian:

I'm sure it's the BCM43<-something->.hcd and/or the bcm43xx*.fw files for the bluetooth.

OK. I finally had some time to look into this. After doing some quick testing, it appears that the Broadcom BCM43438/BCM43455 wireless firmware shipped with SARPi images and packages definitely isn't working. Installing the same firmware from the latest Raspbian Buster image seems to work perfectly.

The latest SARPi Slackware ARM installer images and packages [04 Aug 2019] for the Raspberry Pi 3 and 4 now includes the above firmware which has been tested and verified to be working as expected.

Grab these here: http://sarpi.fatdog.eu/index.php?p=downloads

If you find any further problems please let me know.

Thanks.

[EDIT] First time when I rebooted after updating my wireless interface didn't show up. So...

Code:
~# ifconfig wlan0 up
Now it's working as normal.

Raspberry Pi 3 B+ Wifi NIC not found

My wifi isn't working on the Sarpi64 latest release. I've tried everything listed. Copying from the Raspberry release. Copying brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt to brcmfmac43455-sdio.txt. Wifi still won't show.

SARPi64 is highly experimental and should only be installed on that basis and understanding; and for that porpoise. I shared this work mainly for those who have time to waste on getting things working - and in the hope that it might be facilitating towards a Slackware ARM64 port. For SARPi64, wireless is the least of my concerns and if it isn't already last on the "Todo" list - it is now.
