Re: no wireless networks found ___wicd

What driver are you using? You have two choices: 'b43', which is incorporated in the kernel and 'broadcom-wl', which is in AUR.

You should explicitly choose 1 and blacklist the other (unless you're using b43 and don't have broadcom-wl installed).

Next should be to bring the device 'eth1' up and scan for networks.

Re: no wireless networks found ___wicd

thinks.  i found there is something wrong with my wicd config. the wireless interface should be "eth1" ,like you said ,not wlan0.Now,i it can scan the wireless networks, but cann't connect  it.

connection failed:Could not contract the wireless access  point.

Re: no wireless networks found ___wicd

Here my Dell Notebook:

lspci -vnn | grep 14e4
Broadcom BCM4312 802.11 ab/g

/etc/rc.conf
Modules=(lib80211 wl !b43 !ssb ...)

Daemons=(hal networkmanager ...)

Using Arch 64 and openbox

~/.config/openbox/autostart.sh

cnetworkmanager --connect=router-ssid   --wpa-pass="router_passphrase"

Using broadcom-wl and cnetworkmanager from AUR.  Router Linksys wrt.

Tried out with Wicd but had no luck so I gave up wicd.  Maybe I didn't figure out on how to configure wicd.

System is working fine.

Re: no wireless networks found ___wicd

The 4312 is native to recent kernels.  I assume you are are using 2.6.32 (Check with uname -a )
The wiki at http://wiki.archlinux.org/index.php/Wireless_Setup is a little out of date.  It provides a good overview, but won't quite get you there [mental note to self, maybe a wiki update would be a good weekend project]

The kernel mode driver does need firmware for the 4312. 

If you have not installed the firmware, you will see lines like these in /var/log/everything.log:

Mar 22 13:50:31 odin kernel: b43 ssb0:0: firmware: requesting b43-open/ucode15.fw
Mar 22 13:50:31 odin kernel: b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
Mar 22 13:50:31 odin kernel: b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
Mar 22 13:50:31 odin kernel: b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devic

One installs that using b43-fwcutter.  Note that the version in core is not current and will not process the firmware file you will need.  Grab the TARBELL from the AUR.  Unpack, untar, pkgbuild and pacman -U that version.

grab and untar the firmware from wget http://downloads.openwrt.org/sourc … .5.tar.bz2

Then, use b43-fwcutter to install the firmware to /lib/firmware.  Detailed instructions are here:
http://wireless.kernel.org/en/users/Drivers/b43

Reload the b43 module (or just reboot) and check that the firmware is installed.  Look for lines like the following in /var/log/everything.log

Mar 22 14:28:02 odin kernel: b43 ssb0:0: firmware: requesting b43/lp0initvals15.fw
Mar 22 14:28:02 odin kernel: b43 ssb0:0: firmware: requesting b43/lp0bsinitvals15.fw
Mar 22 14:28:02 odin kernel: b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
Mar 22 14:29:35 odin kernel: b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
Mar 22 14:29:40 odin kernel: b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)

try sudo ifconfig wlan0 up
then try iwlist scan

Do you realize we can't see those? You need to upload them to a file hosting site like http://tinypic.com/ (that's my favorite one). Also, might help to post the output of dmesg. That sometimes gives useful info on what's going on with Broadcom cards when they don't work.
