Ubuntu

wicd not finding any wireless

Asked by angelo ortiz

Hello all. I'm stuck and can't get out (figuratively speaking). Was having difficulty with WICD not finding any wireless networks. Ran sudo ifconfig -a ; sudo ifconfig wlan0 up; iwconfig wlan0 essid Eagle1; iwlist wlan0 scan essid Eagle1; and so on. All indications thru terminal window reflected a wireless signal being detected by my laptop, but WICD wasn't finding any wireless. My ssid is not broadcasted, but WICD allows you to 'find a hidden network'. Entering my ssid info, wicd still found nothing.

Reviewing other threads i saw that i could purge WICD thru the apt-get purge wicd* ; but when i attempted to do an apt-get install wicd, no luck. Looking at another post, i saw reference to synaptic package mgr. I found the wicd pkg, but of course i couldn't install because--I HAVE NO INTERNET CONNECTION. Yes, it was a bonehead moment.

I restarted my box and ethernet connection found. I used synaptic package mgr to install wicd. Still no wireless.

When i do an IWLIST SCAN i see my router with it's hidden beacon: ESSID: "\x00\x00\x00……"
I then executed SUDO IWCONFIG WLAN0 SCAN ESSID EAGLE1, and i see my ssid and associated parameters: encryption key on, bit rates, freq, etc.
But when i go to the wicd n/w mgr, it tells me there no wireless networks found.

I ran DMESG |GREP WLAN0 and saw the following: ADDRCONF (NETDEV_UP), wlan0: link is not ready. Then DMESG |GREP IWL3945, and got this: detected intel wireless wifi link 3945abg. Just before submitting post, i saw the "Check if already posted" button. Reviewing some other threads, i ran LSHW -C NETWORK and saw my PRO/Wireless 3945G info, then i ran RFKILL LIST ALL and saw nothing is blocked.

Read similar posts in this forum and ran several commands:
cat /etc/network/interfaces (everything ok)
lspci -nn (saw n/w controller info related to Pro/Wireless 3945ABG)
sudo /etc/init.d/networking restart (still no change, wicd reflects "no wireless networks found."
cat /var/log/debug |grep wlan (showed previous dates of when wlan was up, attached, authenticated; the last entries however reflected "disabling the bridge, down, detached.")
cat /var/log/messages |grep wlan (showed multiple lines of "wlan0: link is not ready")

I'm at a loss and need help? I'm using Backtrack 5 (Ubunto 10.04).

Hi,

Go to wicd --> preferance --> in general setting you will see wireless interface here you have to add wireless interface name as displayed in ifconfig i think in your case its wlan0

Thanks,

Backtrack 5 is not supported at https://answers.launchpad.net/ubuntu

Backtrack 5 has its own support at http://www.backtrack-linux.org/forums/forumdisplay.php?f=143

Support for Ubuntu 10.04 will end in a few months from now.

I suggest performing a clean install of Ubuntu 12.04 LTS, which is supported until April 2017.

Or else request Backtrack support here:

It's kernel for kermic..
Do you using Backtrack and having problem with wireless card.
And you need wireless for sniffing and spoofing purpose.
IF so then i might help you because back in time i also had same issue.

I took a linux class and BT was the OS we were using along with vmware. I obtained his image, but i dont really need the tools afforded by BT. If i dont get any other recommendations and i'm still stumped then maybe i'll try the sudo aptitude cmd

Can you help with this problem?
