Unable to connect to wireless as of update 22 Jan

riba · 01-26-2021, 08:10 AM

After upgrading with the 22 Jan updates on my raspberry pi 4 8GB Networkmanager was no longer recognising a wireless interface. Thinking I may have made an error somehow I decided to reinstall slackware from scratch on booting into my fresh system I found the same problem plus with no wireless being recognised... in addition to the X displaying freezing in XFCE4.16, but this has already been reported on in another thread. My config.txt file was unchanged from the default one shipped in the install.

Unfortunately I can not supply any data concerning wireless as my pi is the only computer I have and had to install raspian in order to use the internet. As far as the wirless is concerned everything was functional until the update. I appreciate that this may not be very helpful but I am wondering whether it was an issue other people have experienced?

Sure, that's no problem. Some users have had issues with Raspberry Pi wireless LAN in the past. Although in your case it's difficult to know what might be causing it. If you have a spare SD card it might be prudent to install Slackware/Raspberry Pi OS on it so you have both OS and can just swap cards easily to change systems.

Try following this RPi WLAN guide to see if there's anything obvious as to why your wireless connection stopped working:

Post back here with any questions or if you face further problems.

I was curious if this affected my RPi4 4GB as well. I don't often use wifi, but I would like it to be available when I do.

NetworkManager wasn't seeing anything wireless.

Tried a couple of things from https://sarpi.fatdog.eu/index.php?p=wireless-nic:

# lsmod output: nothing jumps out at me as abnormal (looks similar to but not the same as the example at the link, but then I don't know what it all means.)

# iwconfig wlan0
gives
wlan0 No such device

Tried
# modprobe brcmfmac

# lsmod and # iwconfig wlan0 give same output, but I wasn't expecting anything different.

Looked at https://slackware.uk/sarpi/extra/sarpi-hacks.README
and noted these new firmware files absent from /lib/firmware/brcm
brcmfmac43455-sdio.bin
brcmfmac43455-sdio.clm_blob
brcmfmac43455-sdio.txt

btw this was present, along with a few other 43455 and 43430 files
brcmfmac43455-sdio.raspberrypi,4-model-b.txt

so I followed these sarpi-hacks.README instructions
# touch /lib/firmware/brcm/brcmfmac43430a0-sdio.bin
then reinstalled hacks
# upgradepkg --reinstall sarpi4-hacks-4.0-armv7l-1_slackcurrent_22Jan21_sp1.txz

After that, these new firmware files were in /lib/firmware/brcm
brcmfmac43455-sdio.bin
brcmfmac43455-sdio.clm_blob
brcmfmac43455-sdio.txt

Still no wifi, NetworkManager was not seeing anything.

Reran

# modprobe brcmfmac

# lsmod and # iwconfig wlan0 still gave same output

Reboot

# lsmod and # iwconfig wlan0 still give same output, and NetworkManager is still not showing anything wireless

It's bedtime now, so that's as far as I'll take it tonight.

Suggestions for next steps welcome.

OK guys. As this was looking like another wireless issue I wasted some time testing on the RPi4/4GB. I've already installed the latest SARPi shizzle (dated 26Jan21) because I built and tested this yesterday, but I don't use wireless generally so did not test it at that time. However, I have this morning.

I was starting from scratch with this, having no previous wireless connection configured, and I am using the onboard RPi wireless NIC and drivers/modules from the latest sarpi4-hacks-4.0-armv7l-1_slackcurrent_26Jan21_sp1.txz pkg.

Basically, I logged in remotely via Ethernet connection and followed this guide: https://sarpi.fatdog.eu/index.php?p=wireless-nic

Code:

root@torq:~# ifconfig wlan0
wlan0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether dc:a6:32:67:c4:2c  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Code:

root@torq:~# ifconfig wlan0 down
root@torq:~# rmmod brcmfmac

The wlan0 interface has been disabled and the wireless modules for the device have been removed. So, now I reload the modules...

Code:

Me, too.

A couple of possibly relevant differences between how I installed SlackwareARM the first time and this second time, off the top of my head:

- First time I installed with DHCP and first used wicd, then switched to NetworkManager. This time I installed with NetworkManager.

- The second time I installed, I had (and still have) my router with fixed IP for both ethernet and wifi.

I will dig into my network configuration when I have some time.

I don't have an answer to your wireless problem(s). RPi4/4GB onboard wireless is working as expected for me. Slackware ARM current is fully updated with all available pkgs (except for kernel/headers/modules/firmware) and running...

Code:

Fully up to date here, too, which is why if yours is working and mine isn’t, I suspect mine is a config problem. I suspect also some config problem for the others here.

Delete all configs, driver modules etc. and start over. My wireless setup wasn't pre-configured as I'd never used it, although the brcmfmac module was loaded. I got rid of it and started over from nothing. Then it worked first time.

rsamurti · 01-28-2021, 09:02 AM

I made a fresh install on my RP4/8GB board using the installer and all the updates of 26Jan21.

Wireless connection is still not possible on my RP4/8GB using on-board wi-fi interface.

lsmod shows that brcmfmac is loaded. But still wlan0 is not available. I tried rmmod brcmfmac and modprobe brcmfmac. But still no wlan0. I am using NetworkManager. Wired network is working fine.

I am unable to solve this.

Not sure what might be causing it. The RPi4 [4GB] onboard wireless is working for me as expected. Perhaps a USB wireless adapter might work instead.

drmozes · 01-29-2021, 03:56 AM

The first step is to look at the logs.

Code:

find /var/log -type f -not -name '*[0-9]*' -maxdepth 1 -print0 | xargs -0 grep  NetworkManager

TheTKS · 01-31-2021, 05:04 AM

wlan0 now visible. Posting with ethernet cable unplugged and internal wifi working.

What worked for me was:
1. Deleting all files in /lib/firmware/brcm (actually moved them elsewhere in case any needed later)
2. Reinstalling sarpi-hacks

Compare those with sarpi-hacks.README of 17 Jan 2021

Code:

3. Raspberry Pi wireless adapter firmware. 

   ** ONLY Raspberry Pi 3 and later versions which feature the on-board 
   Cypress wireless and Bluetooth adapters. **
   
   Replaces defunct Bluetooth, brcmfmac43430 and brcmfmac43455 firmware 
   in the /lib/firmware/brcm directory. Old firmware files are removed  
   and new firmware files are installed:
   
   [New firmware files]
     BCM-0bb4-0306.hcd
     bcm43xx_hdr-0.fw
     bcm43xx-0.fw
     brcmfmac43430a0-sdio.bin
     brcmfmac43430a0-sdio.jumper-ezpad-mini3.txt
     brcmfmac43430a0-sdio.ONDA-V80 PLUS.txt
     brcmfmac43430-sdio.AP6212.txt
     brcmfmac43430-sdio.bin	
     brcmfmac43430-sdio.Hampoo-D2D3_Vi8A1.txt
     brcmfmac43430-sdio.MUR1DX.txt
     brcmfmac43430-sdio.raspberrypi-rpi.txt
     brcmfmac43430-sdio.txt
     brcmfmac43455-sdio.bin	 
     brcmfmac43455-sdio.clm_blob
     brcmfmac43455-sdio.txt

Those three lists are different. I haven't tried if Bluetooth works.

Looking back, it may have been foolhardy to remove that whole file list and then run only sarpi-hacks. I probably should have run # upgradepkg --reinstall [ all sarpi kernel packages ] and # slackpkg reinstall [ SlackwareARM kernel-firmware]. I'll go do that and report if any new files show up in /lib/firmware/brcm.

Reinstalled all sarpi and kernel-firmware packages, in this order:
source, modules, kernel, headers, kernel-firmware, boot-firmware, sarpi-hacks

Code:

# upgradepkg --reinstall sarpi4-kernel-source-5.10.11-armv7l-1_slackcurrent_28Jan21_sp1.txz kernel-modules-sarpi4-5.10.11-armv7l-1_slackcurrent_28Jan21_sp1.txz kernel_sarpi4-5.10.11-armv7l-1_slackcurrent_28Jan21_sp1.txz kernel-headers-sarpi4-5.10.11-armv7l-1_slackcurrent_28Jan21_sp1.txz

# slackpkg reinstall kernel-firmware-20210119_0578970-noarch-1

# upgradepkg --reinstall sarpi4-hacks-4.0-armv7l-1_slackcurrent_28Jan21_sp1.txz sarpi4-boot-firmware-armv7l-1_slackcurrent_28Jan21_sp1.txz

That put me back to wifi not working, and the previous file list in /lib/firmware/brcm (total 17404), the first list in post #13 ^

So again deleting all brcm firmware files

Code:

/lib/firmware/brcm# rm *.*

then reinstalling sarpi-hacks

Code:

# upgradepkg --reinstall sarpi4-hacks-4.0-armv7l-1_slackcurrent_28Jan21_sp1.txz

then rebooting

I am again able to connect to wifi. With my ethernet cable plugged in, in NetworkManager I can manually switch between wired and wifi, and if I disconnect my ethernet cable, network connection automatically switches to wifi.

I followed your advice. Now both wifi and wired connections are working. Thank you so much for reporting this.
