Wifi stopped working

[CGeTech]

Hello,

I have upgraded to  tc-5.x, after upgrading my wifi stopped showing anything to select.

Please refer to screen shots and advise.

Hello,

Please help !!

[coreplayer2]

Please show results of   

dmesg | tail -50


Edit:  ok hold on I see you have a Broadcom wifi device.

Hello coreplayer2,

Please refer to the screenshot for the output in case you still need it.

Your screenshot doesn't show up on the one system I was using, but now that I see it..   Have you tried blacklisting kernel modules  bcm, ssb and b43 to use wl (broadcom modules ?

install " wl-modules-3.8.10-tinycore.tcz " extension, then

Append " blacklist=bcma,ssb,b43 "  to your boot config file eg:
 

Code: [Select]

APPEND initrd=/tce/boot/core.gz loglevel=3 blacklist=bcma,ssb,b43


[coreplayer2]

Alternatively, (maybe you should try this first) have you installed the missing firmware as indicated in your screenshot?

This firmware may resolve your issue

install " firmware-broadcom_bcm43xx.tcz " extension



Please advise which method resolves your issue

Hi CGeTech
Just a few observations. There appears to be a stack trace at the top of the screen shot, you might want to see what lead
up to it with:

Code: [Select]

dmesg | tail -80It looks like some firmware was loaded since a version number is listed, though the date of 2015-15-255 seems
rather odd.
I don't see a  pcm5.fw  file available in the 4x or 5x repository.
Rather than posting screen shots, redirect the output of commands into a file like this:

Code: [Select]

dmesg | tail -80 > dmesg.txtYou can then open the file with  editor  and copy and paste the contents between  code tags  when you post.

I think the missing pcm5.fw is located with the archive bcm43xx firmware, if not then the cutter will extract the necessary fw

AIUI the cutter extracts pcm5.fw from b43 binary (but have never tried it)

Append " blacklist=bcm,ssb,b43 "  to your boot config file

Isn't it bcma instead of bcm?

[coreplayer2]

You are correct sir   

ok corrected

Hello,

I tried blacklist but still not working.

DEFAULT core
LABEL core
KERNEL /tce/boot/vmlinuz
APPEND initrd=/tce/boot/core.gz quiet waitusb=5:UUID="85089724-c18e-4783-a6fb-64f490a0465c" tce=UUID="85089724-c18e-4783-a6fb-64f490a0465c" loglevel=3 blacklist=bcma,ssb,b43

Hi CGeTech
A google search for     eth%d: 5.100.82.112 driver failed with code 21    may provide some clues.

[Juanito]

What did you do about the firmware?

the wl module works for my hardware in both tc-4.x and tc-5.x without firmware being required.

[CGeTech]

Hello,

I removed blacklist and after that it seems some file is missing please  refer to attachment.

DEFAULT core
LABEL core
KERNEL /tce/boot/vmlinuz
APPEND initrd=/tce/boot/core.gz quiet waitusb=5:UUID="85089724-c18e-4783-a6fb-64f490a0465c" tce=UUID="85089724-c18e-4783-a6fb-64f490a0465c"

Removing the blacklist causes tc to load the b43 driver, which may or may not be suitable for your hardware, and will clash with the wl module.

It's probably best to visit the linux wireless web site to check if your hardware is compatible with the b43 driver - if it is compatible then b43 + firmware is probably the way to go, if it is not compatible, then wl without firmware is probably the way to go.
