[SOLVED] Changed daemons & wireless stopped working

So my problem started after I edited rc.conf to change my daemon array and rebooted. I simply removed network from the daemons sections, rebooted, and upon reboot networkmanager showed no wireless connection. So I re-edited my rc.conf file and placed network back where it was, rebooted again, and the problem still exists.


In rc.conf my networking section looks like this:

eth0="dhcp"
wlan0="dhcp"
INTERFACES=(eth0 wlan0)

In rc.conf my daemons sections looks like this:

DAEMONS=(syslog-ng network netfs crond alsa dbus hal networkmanager)

iwconfig output:

[root@N01 ~]# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

lspci output:

[root@N01 ~]# lspci | grep Network
02:03.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

Any help would be greatly appreciated.

Re: [SOLVED] Changed daemons & wireless stopped working

if my memory serves me correctly, you need to disable your interfaces and the default network daemon for networkmanager to work.

INTERFACES(!eth0 !wlan0)

DAEMONS=(syslog-ng !network netfs crond alsa dbus hal networkmanager)

Re: [SOLVED] Changed daemons & wireless stopped working

Well I banged my interfaces and network, but my wireless problem is still not solved. iwconfig still doesn't list wlan0.

Note: wireless was working perfectly before removing network from the daemons and rebooting.

Re: [SOLVED] Changed daemons & wireless stopped working

Perhaps the output of lspci will give some clues (ie is the hardware being detected or has that broken) which could direct people to a useful solution.

Well I already posted the lspci output for my wireless, but here is the output for all devices for whatever it's worth:

[root@N01 ~]# lspci

02:03.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

Ok just for reference, I went here: http://linuxwireless.org/en/users/Drivers/b43/devices to double check that I had the proper driver installed. the site told me to issue the following:

[root@N01 ~]# lspci -vnn | grep 14e4
02:00.0 Ethernet controller [0200]: Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02)
02:03.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

the part in brackets at the end is the pci id: [14e4:4318] which tells me that my device is supported by the b43 driver, according to the chart here: http://wireless.kernel.org/en/users/Dri … CI_devices

I have reinstalled b43-fwcutter and the firmware for my b4318. I also tried the rmmod and modprobe commands to no avail.

Re: [SOLVED] Changed daemons & wireless stopped working

Being that I thought I had done everything that I possibly could on the software side of things, I shut down my laptop and opened her up. I re-seated the wireless card, powered her back on, and voila! The wireless is working again. I don't really understand why this happened or why re-seating the card fixed it, but for now I will mark this thread as solved. If anyone can tell me why this fixed the issue and or how to prevent it from happening in the future, please let me know.

Well I guess sometimes things are just badly manufactured and so a slight bump can knock them off. I remember my (VERY) old Atari 520STFM (back in 1990) would sometimes refuse to let me use the joystick ports. Opening it up revealed a poor bit of design, with the ports soldered directly to the motherboard, which meant that if they moved slightly the joystick would stop working. Of course the solution was to get a few short wires, solder one end to the board and 1 to the port, leaving just enough slackness in the cable that the port could move freely without disrupting the mobo. It worked. Maybe this is something similar, ie a poor bit of design.

Re: [SOLVED] Changed daemons & wireless stopped working

Well, I weighed the possibility that it may have just been a coincidence; but if so, it's ironic that I remove 'network' from the daemons, bump my laptop enough to knock the wireless card loose, and all at about the same time haha. What else is boggling is that my system recognized the device, and didn't at the same time. I guess I just don't like fixing something without knowing exactly why what I did fixed it.
