Followed the steps outlined in the guide exactly and now WICD can't locate any wireless networks! It's worst than before! Installed Wifi Radar and it found my AP, Nexus, but I still can't connect. What now?

If possible, I can install Gitso and let you take a look yourself. We'd post the solution and the steps taken to get there here for everyone's benefit.

Ohhhhh yeeaaaahhh, I can just FEEL the love!! lol = )


Here's what doxanh wrote:

Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

Ok I got it solved. My problem is the same as the one described here.

The drawback is that I have to manually use wpa_supplicant and run renice every boot. Kinda annoying but no fix to this time.

Thank you kevdog.


I entered the command exactly as described in the posting he referenced: http://ubuntuforums.org/showpost.php...22&postcount=4 . . . and nothing happened. Still can't connect.

What's worst, WICD no longer sees any wireless APs. Wifi Radar can see them but I still can't connect to Nexus. It's not able to obtain an IP address.

What now?

Okay two assumptions, (a) you have found your wpa_supplicant.conf file and checked that it has the exact same settings as doxanh has/had except for your keys, and (b) you have checked your /etc/network/interfaces file and you have the same settings as doxanh except yours will have 192.168.1.x,y,z.

If you have all that checked and double checked - I would like you to check if you have and ifstate file, it should, if my memory serves me correctly, be in /var/run/ directory in a karmic koala installation. It should at a minimum show two lines the first will be lo=lo and the second, when you have a wireless setup, should be eth2=eth2 otherwise it would be eth0=eth0 for a wired connection. If this 'ifstate' file doesn't exist, I need to know, but I warn you that I will have to do some searching for exactly how it gets created, because I have forgotten.

Incidentally, again IIRC, the karmic wpa_supplicant.conf file also hangs out in /var/run if it isn't in the /etc/wpa_supplicant/ directory.

Lets us know how you get on.

I think we have a bigger problem.

When I run lshw -C network here's all I get:

Wireless interface is gone!! What happened? How do I restore it?

Here are the contents of my ifstate file:

#!/bin/sh

iface="$1"
if [ -z "$iface" ] ; then
echo "Usage: $0 IFACE"
exit 1
fi

if ifconfig "$iface" | grep -Fw UP >/dev/null
then
echo UP
else
echo DOWN
fi

I presume that your eth2 is not working for your last post. Remind me what you are using as a network manager and/or wifi-radar etc.

Have you tried running: # ifup eth2

And then: # iwconfig eth2

If it doesn't show your Nexus ap then does: #iwlist eth2 scan

return anything?

That worked.

However, WICD does not detect any wireless networks despite the fact that iwlist eth2 scan did. WiFi Radar detects all available wireless networks but I can't connect to Nexus. I get a "Could not get IP address" error.

Wifi-radar is telling me that you have it set as dhcp in the Nexus configure button, IIRC I did somewhere in this thread make a listing of the suggested settings for your Nexus wifi-radar setup. You would have to click on save and then disconnect and then connect to see if you settings work.

Anyhow once you know what it is/was you can edit your /etc/rcX.d directory (full of shell scripts) where X equals your runlevel - then just delete the s24dhcpbd entry -anyway that is what mine was [its gone now and I had to look in /etc/rc3d to see what it was - incidentally if you want it back just copy the entry from a different runlevel]. I also got rid of avahi-daemon which played silly b___ers with searching for DNS servers.
If you haven't got one yet I now have S51wifi-radar linked to /etc/init.d/wifi-radar.

You may have to reboot, as I am not sure that logging out and back in reruns then runlevel scripts

hope this helps
I checked my rc2.d directory and I don't have a s24dhcpbd entry. Is there another way for me to disable dhcp? I came across this post but I don't know if I should follow these instructions: http://ubuntuforums.org/showthread.php?p=8625406. What do you think?

Also, my Broadcom B43 and STA wireless drivers are not activated. In fact, I can't activate the STA driver at all. It causes a system crash when I try.

A) You are not using the b43 module, you are using wl, according to your lsmod output in post #1,

B) I have never heard of an STA driver for wifi, you may be referring to ssb which accompanies the b43 module,

C) See my post #85 for the wifi-radar settings that I suggested to avoid dhcp, if when you try these settings dhcpd continues to interfere with your wireless connection or the functioning of wifi-radar, then

D) Follow the instructions that you posted from the ubuntuforums, which sound reasonable to me.

Just wanted to comment on one thing from above:

The "STA" drivers are the ones from Broadcom themselves, from what I recall; they're relatively new. Not sure what STA means, but that's what they're called (if I'm remembering *anything* correctly )

Cheers!

STA is Broadcoms's name for the wl driver. They are one and the same and different people use them interchangeably. As far as I know, there are 4 different Broadcom drivers out in the wild:


1) ndiswrapper + Windows driver
2) bcm43xx - predecessor to the b43 series and is now deprecated. Needs firmware from fwcutter
3) b43/b43-legacy - current drivers in the kernel. Appears to be functional at install time, but actually needs firmware from fwcutter to work.
4) STA/wl - Broadcom's official driver. Officially works on 4311, 4312, 4321 and 4322 chipsets but I've seen reports it works on a couple of others. This one is standalone and needs no additional firmware.

You might also consider the ssb module to be part of the b43/b43-legacy driver as it seems to be required.

New problem. Here's my iwconfig output:
iwconfig
lo no wireless extensions.

eth0 no wireless extensions.


Here is my lsmod output: http://pastebin.com/mffff4f4

Since ndiswrapper and b43 are listed does this mean that they are installed? If so, why are no wireless extensions detected?
