#Wireless Connection Issues#

Hi everybody,
I've got an issue for you, which is gonna sound probably stupid.. to the most of you here, but everybody with his talent, right? :) Ok, check this out, I've installed BackTrack 2 in my USB flash drive, so, I boot it from there without having any problems. My laptop is an HP Pavillion dv2000, and it's wireless network card an Intel 3945ABG PRO (as usual..). I performed the following steps (after I read it from another web page) in order to enable my 3945 card:

Code:

Open a console and type: cd /usr/src/drivers/ipw3945-1.2.0 Hit enter then type load Hit enter Your Intel® PRO/Wireless 3945ABG can now be found at eth1 For Those of you that have backtrack2 installed on your hdd. To save typing all that in every time you restart. Open a console and type alias 3945="cd /usr/src/drivers/ipw3945-1.2.0" Hit enter now all you have to do to enable your Intel® PRO/Wireless 3945ABG is type 3945 Hit enter load Hit enter replace 3945 with whatever keyword you want as I only used it as an example

After this I run the Wireless Assistant 0.5.5 Application, and voila.. I can find some wireless networks...but I cannot connect to them, I mean, I click on one..and no matter if I enter my network's key it says all the time 'Connection Failed'. I don't know if whatever I told ya above is actually required but I thought to write the whole story once.
Thanks in advance anyway..;)

Drop wireless assistant and do what us pros do.....Use the command line.

ifconfig <device> down
iwconfig <device> essid <networknamehere> key <wepKeyhere>
ifconfig <device> up
dhcpcd <device>

""iwconfig <device> essid <networknamehere> key <wepKeyhere>""

Another question, we're talking about WEP.. my network uses WPA2.
Is there any change in the command?

(Also, I just did what you told me and when I'm writing the network key it says:
"" -bash: syntax error near unexpected token ')' "" )

Ok, I figured out a couple of beginner things..
I'm at this point:

My only problem now is that when I run the wpa_passphrase myNetworkName wpaPassphrase command it says to me this : Passphrase must be 8..63 characters.
My network's key is 42 characters. How do you explain that ?

Hi Im having a strange network connecting problem. Im running back Track 2 and Im having problem connecting to a specific wlan.

For Example if I use the Wireless assistant i can see my wlan, and when i try to connect with the correct WEP key it says "connection failed". Note I get the exact same problem trying to connect to another unprotected wlan.
I've also tried to connect just though a shell (the "pro" way) and it doesen't work either.

Now to the wierd part: When i boot BT2 it searches for wlans to connect to and it finds one( the unprotected i mentioned earlier) and connects. So if i try to connect manually to any wlan it doesen't work, but if it finds one itself(unprotected) it works!!

Help appreciated.

Connecting to Wireless Networks using IPW3945

HOPE THIS MAY BE OF USE !!

I don't know if you have found a fix to your problems, but this is how I connect to my WEP network.

My Setup
Device: Dell Latitude D620
OS: Backtrack 2 Final (installed to HDD)
Ethernet Adapter: Intel 3945ABG

1. Log into Backtrack 2 as ROOT.

2. Go to:
Menu > Backtrack > Radio Network Analysis > 80211 > ALL > IPW3945

3. With the Konsole window still open, load Wireless Assistant:
Menu > Internet > Wireless Assistant

4. Find your network & click "Connect", either connect using your already configured connection or go through the wizard & create a new connection.

NOTE !! - making sure that you've got everything corrent. SSID, WEP Key, Open/Shared Key etc.

5. If it fails to connect, close Wireless Assistant & load IPW3945 again, step 2.

6. Load Wireless Assistant again (step 3) & click "Connect" again.

The reason why I've done these simple notes, is because sometimes my adapter wouldn't connect to my wireless network the first time I loaded the IPW3945 driver, but it would the 2nd time. Simple but it worked for me.

I apologize if these notes are of novice standard, I am fairly new to the Backtrack OS.

Do you have any special characters in your passphrase? If so, have you tried to put a “ on each extreme end of the passphrase?

First of all Wireless Assistant is shit, drop it and use the command line and it will spare you a lot of connection issues. Secondly have you tried to issue the following commands before you try to associate to the network:

Code:

rm /etc/dhcpc/* dhcpcd –k interface
