How to Start Networking in Backtrack

[sickness]

I just deleted the ones I don't use and added my wlan1 which was my adapter, than downloaded wireless drivers from the internet and installed them.

[oceans11]

The first commands wouldn't start anything for me, I did some searching and found this instead :

cd /etc/init.d
bash networking start

Which does the job properly.

This worked for me too. For a little while. I could see wireless networks and connect to them. But after a few days it stopped working. I can't see or connect to any wireless netowork. I am using broadcom bcm4318 BT4 hard drive install.

Hi my Backtrack 4 wireless connection problem .

iwconfig wlan0 essid (networkname) key (psw)

but this problem

Error for wireless request set encode (8B2A)

invalid argument (psw)

whats problem

I was getting this error as well.

To connect to wireless using WPA/WPA2 in Backtrack 4:

1. Create a file /etc/wpa_supplicant.conf, copy and paste in the following

network={
ssid="<network>"
psk="<key>"
}

Replace <network> with the name of your network, e.g. linksys, and replace <key> with your passphrase e.g. p@$$w0rd.

Now save it.

2. In a new shell write:

chmod 755 /etc/wpa_supplicant.conf

Hit return.

3. Then,

wpa_supplicant -i <interface> -c /etc/wpa_supplicant.conf

replace <interface> with the name of your interface, e.g wlan0

Hit return again.

You will see some action in this shell, leave it open and open another one.

4. Finally,

dhclient <interface>

replace <interface> with the name of your interface, e.g wlan0

Hi there,

I am having trouble getting connected to my wireless (wlan0). Dhclient works fine on my wired(eth0) but times out on my wlan0 interface.

[BT4 Medium]: Laptop hard drive install
[Adapter]: Broadcom BCM4306 (rev3)
[Router]: Linksys WRT54GX
[Encryption]: WPA

Everything seems to be functioning but I do not see any Wireless Networks listed when I open WICD. BT4 detects my adapter and all of the wireless tools detect it as well. I had it seemingly working for a bit last night (detected my network and a neighbors), but when I turned my laptop back on it was not functioning. I have a feeling it is similar to the other posters issue about having to be directly beside the AP, however I can't replicate it with enough accuracy to be sure and the fact I picked up a random network also contradicts that claim. I know the AP is fine as I have another laptop (although running windows) that is able to connect and there are no filters configured. Any insight on this?

I've followed guides on the wpa_supplicant, bc43xx drivers, interfaces file, and wicd. I just did a fresh install of BT4 in an attempt to see if I made anything worse by editing settings.

I have read through this thread and tried any relevant fixes to no consistent success. After looking through many WLAN Linux guides online I am stumped.

Any help would be appreciated. Sorry if I left out any pertinent information.

Thanks.

[amtesh]

I figured it out.
I had to disable the ShrewSoft DNS Proxy Daemon service and so I got a fully working bridged VMware Backtrack with DNS resolution.

if you are using vmware fusion just do /etc/init.d/networking start

also you can enable the ethernet card, usually is eth0

ifconfig eth0 up
dhcpclient eth0 up
