SOLVED: Wireless Module unloaded?

[dkeg]

so I am not sure what happened, but when I booted up this morning I had no wireless. I did before I shutdown. My card is not even being picked up now. So I guess somehow the module was unloaded? Has anyone experienced this before? I did not have a chance to investigate any further. This is my plan of action for later on.

I'm on Kielbasa rc1 on an Acer Aspire TimelineX

Wireless card = broadcom BCM43225

EDIT: This is what did the trick

Code: Select all

sudo modprobe -r brcmsmac
sudo modprobe brcmsmac

Code: Select all

#is the module stilll there
fw-detect OR lspci -nnk | grep net

#load the wl module.
modprobe wl

# Just in case, might need to unload conflicting modules
modprobe -r b44 b43 b43legacy ssb brcm80211

are these the correct steps? I'm at work atm. This is what I was able to eek out with research during lunch.

Hi drew,

no idea what could have caused this.

yeah, who knows. I checked those links and 1. was glad to see I was on right track, and 2. added to my list. I think I have a good cheat sheet to utilize later.

thanks mb

until later...

[dkeg]

marked SOLVED. Added in what worked in original post

okay this worked

Code: Select all

sudo modprobe -r brcmsmac
sudo modprobe brcmsmac

whew!

[machinebacon]

You did it like a steak: well done! :D

[dkeg]

bump...
so every time I boot up, I have to run those commands.

Code: Select all

modprobe -r brcmsmac
modprobe brcmsmac

to get wireless going. I checked systemd to see if something changed there and in modules-load. Didn't see anything to helpful. I guess I could just create a script to run at startup, but I'm sure there is a more proper way that used to happen but now doesn't

Hi Drew,

no, you don't need to. If you want a module to be loaded at boot:

Code: Select all

sudo nano /etc/modules-load.d/modules.conf 

and there simply place

Code: Select all

brcmsmac

Save and exit. This should work now.

[dkeg]

nice, thanks. I found that file, it's empty atm, but was not sure what I would need to enter, ie, the full modprobe ..... or what. That's so simple. So question, was that there before and it got wiped. Did the file get replaced somehow?

Thanks, I'm psyched, learned something new. Appreciate it mb!

[machinebacon]

No, it's empty by default. It is possible (pussybear) that another module blocks the module, in this case we would have to find out which modules use the same driver and blacklist them.

What you mean for 'modprobe <module>' in the post before is the /etc/rc.local file, there you can call modprobe just right before login.

You can also use this method to play a startup sound, for example.

Code: Select all

sudo nano /usr/bin/startup

#!/bin/bash
files=(/usr/share/startup/*)
mpg123 "${files[RANDOM % ${#files[@]}]}"   # replace mpg123 with mplayer/aplay/vlc/...
exit 0

make it executable (sudo chmod +x /usrbin/startup)

then in /usr/share/startup/ you place your sound clip(s)

and finally, in /etc/rc.local you write the command

Code: Select all

/usr/bin/startup

right before the 'exit 0'

[dkeg]

the first suggestion did not work for me. So possibly as you eluded to maybe another module is using it and that module must also start at boot. I'm thinking that b/c when I used your other method by adding to the rc.local and creating a script in /usr/bin, that did work.
so /usr/bin/brcmsmac

Code: Select all

#!/bin/bash
modprobe -r brcmsmac
modrprobe brcmsmac
exit 0

Thanks for the help
