Wicd doesn't detect wifi networks

Just installed Arch in a Dell Inspiron 1525 and after some fights, almost everything is working perfect, except for the wifi.

I used this guide: http://wiki.archlinux.org/index.php/Broadcom_BCM4312
not sure if i make a mistake, i don't think so, but... who knows

After that, i installed Wicd, but it doesn't detect wireless networks (wireless is already set as wlan0). Wired nets works perfect so far (only tested in my house)

Well
When i type iwconfig:

lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bg  Mode:Managed  Access Point: Not-Associated   
          Tx-Power=0 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

and here is ifconfig:

eth0      Link encap:Ethernet  HWaddr 00:1E:C9:F9:20:23  
          inet addr:192.168.1.103  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

and some stuff from rc.conf:

...
MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated
MODULES=(lib80211_crypt_tkip)
...
eth0="dhcp"
INTERFACES=(!eth0 !wlan0)
...
gateway="default gw 192.168.1.1"
ROUTES=(!gateway)
...
DAEMONS=(syslog-ng !network dbus netfs crond alsa hal wicd)
...

any idea to get the wifi?
Thanks guys.

Re: Wicd doesn't detect wifi networks

What is the output of 'iwlist scan' ??
If it complains that wlan0 is down, try 'sudo ifconfig wlan0 up' first.

I have a feeling you are not associating either because the radio is off, it doesn't know with which essid to associate, or the network is encrypted.

Re: Wicd doesn't detect wifi networks

This is "iwlist scan"

lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

wlan0     Failed to read scan data : Network is down

you were right.
then tried  "sudo ifconfig wlan0 up" and got this:

SIOCSIFFLAGS: No such file or directory

Update:
Just checked /var/log/messages.log and found this:

Apr  8 17:03:59 DeathStar kernel: b43 ssb0:0: firmware: requesting b43/ucode15.fw
Apr  8 17:03:59 DeathStar kernel: b43 ssb0:0: firmware: requesting b43-open/ucode15.fw

missing firmware?

Re: Wicd doesn't detect wifi networks

I have an Inspiron 1525 too, but it has the 'PRO/Wireless 3945ABG [Golan] Network Connection module' which uses the iwl3945 module instead. However, I installed Arch on my daughter's HP/Compaq Mini 110c notebook and it does have the Broadcom BCM4312 wifi interface.

Here's what I needed to get it working on the 110c with wicd (versions might be a bit out of date now):
#pacman -U broadcom-wl-5.10.91.9.3-1-i686.pkg.tar.gz  # from AUR
/etc/rc.conf: MODULES=(... lib80211_crypt_tkip wl !b43 !ssb ...)  # NB: Using wl NOT b43 module

Though it works fine, I did find that the network interface randomly swapped between eth0 and eth1, so I had to do something like:

udevadm info -a -p /sys/class/net/<device> | grep address  # check MAC addresses
create: /etc/udev/rules.d/10-network.rules (MACs must be lowercase):
   SUBSYSTEM=="net", ATTR{address}=="00:xx:xx:xx:xx:xx", NAME="eth0"
   SUBSYSTEM=="net", ATTR{address}=="0c:xx:xx:xx:xx:xx", NAME="wlan0"
Then specify these devices in Wicd preferences

Hope this helps.

Re: Wicd doesn't detect wifi networks

there was broadcom-wl 5.60.48.36-1 already installed and lib80211_crypt_tkip was already in the modules list, wl didn't, but there was no difference when i added it anyway

This is not bad.  Any other lines containing 'b43' ?
I ask, because the fact that the network shows up says the kernel thinks it is there and is usable. 

Which Broadcom chip do you have? ( what is the output of lspci  ?)

Just got into the web that the output gave me and followed the instructions... this time it worked smile

now i can detect wifi arround, but its unable to get the ip adress when connecting =/


UPDATE: Just rebooted and got no internet at all, including wired connection was unable to get an ip
then i panic and tried to install networkmanager
looks like it worked but i dont see any tray icon or something to start a gui, but anyways, i have wired connection.

my new rc.conf looks like:

MODULES=(lib80211_crypt_tkip !wl b43 uvcvideo)
...
eth0="dhcp"
INTERFACES=(!eth0 !wlan0)
...
DAEMONS=(syslog-ng !network dhcdbd dbus netfs crond alsa hal networkmanager !wicd)

it was so near to get wifi connections sad
well, any help to get wifi enabled would be great, doesn't matter if this is using wicd or Network Manager, =P

But did you try specifically blocking the loading of b43 - by adding !b43 to the modules list?

Re: Wicd doesn't detect wifi networks

yes, i already did and there was no difference.
now i have done several iwlist scan and some times it actually scan and give some net's info. I realized that the scan is ok seconds after y manually turn off the antena with the laptop switch.

well i think i will play arround with the settings to get some extra info.
is there any chance that after messing around with drivers and stuff now i have some kind of conflict that cause problems with the wifi?
i mean, i followed many different "how to's"...


tranks guys


UPDATE: Just tried once again with wicd. changed the rc.conf to suit wicd needs and after some iwconfig, ifconfig and stuff realized that there was a new "eth1" device, put it up with iwconfig eth1 up and changed the wicd settings and now i have wired net (again) with wicd. wlan0 isn't at the device list of iwconfig or ifconfig anymore, and wicd doesn't show wireless networks.

Some outputs:
