* i tried dhclient times out too
* if I use airmon to set the channel I get perm denied from iwconfig when I try to set the essid

Code:

# SSID is set right bt stuff # iwconfig wlan0 wlan0 802.11b/g ESSID:"ags_guest" Mode:Managed Channel=4 Access Point: Not-Associated Bit Rate=11 Mb/s Tx-Power=5 dBm Retry:on Fragment thr:off Encryption key:off Link Quality=0/100 Signal level=-178 dBm Noise level=-156 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 bt stuff # airmon-ng start wlan0 1 Interface Chipset Driver wifi0 Atheros madwifi-ng wlan0 RTL8187 r8187 (monitor mode enabled) # then i lose the ssid that is set .. bt stuff # iwconfig wlan0 wlan0 802.11b/g Mode:Monitor Channel=1 Bit Rate=11 Mb/s Tx-Power=5 dBm Retry:on Fragment thr:off Link Quality:79/100 Signal level:-215 dBm Noise level:-235 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 # try to set it back ... bt stuff # iwconfig wlan0 essid 'ags_guest' Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Operation not permitted.

using wlan0 RTL8187 r8187

how do I connect I know DHCP works using ATH0 ( on board ) when I use

iwassistant I get errors when it sets the channel so not sure what I am missing..

if I disable the onboard and boot iwassistant gives the same error

I have the alfa 500 MW and use the default drivers provided by bt2 and bt3.

Drop wirelessassistant and use the command line. ;)

Here are the commands I use.

Code:

1. Go to /etc/dhcpc ...and inside this folder DELETE EVERYTHING! 2. Ifconfig wlan0 down 3. iwconfig wlan0 essid "Xploitz Network" key c6e679d9a2 4. Ifconfig wlan0 up 5. dhcpcd wlan0

That should do the trick to get you internet connection. ;)

If you want to use airodump and enable monitor mode.....

Code:

1. airmon-ng start wlan0 6 (for channel 6, put your channel of your AP here) 2. airodump-ng -c 6 wlan0 (again, my AP is on channel 6 so I used -c 6..put your AP's channel here)

Hope this helps!

Its because you are trying to do it in monitor mode it seems by your post.

-=Xploitz=-: Thanks for the help but I tried that same error and also tried dhclient Using *Bt3 also
* ath0 works fine so I know its not the AP etc ..
* again I can crack WEP but cant connect to it .. ( how that works is beyond me .. )

pureh@te: No only reason I tried airmon is to set the channel ( as that is the only error I ever get is when setting the channel with iwconfig

BTW working on w3af -g to work with Bt3 and will put in in a lzm if need be :O

you dont need to set the channle manually for connecting to a network.

Just give it the AP's essid and it will change to the desired frequency. follow Xploitz's instructions, theyre correct.

I just noticed your AP's name. >>>ags_guest

it has a special character in it. You'll need to surround its name with double quotes like this.....

"ags_guest"

Please start over and put the following commands in your shell EXACTLY (except put your key in where my c6e679d9a2 is. )

Code:

ifconfig wlan0 down iwconfig wlan0 essid "ags_guest" key c6e679d9a2 ifconfig wlan0 up dhcpcd wlan0

Any success this time??? :confused:

* booted with both cards ( onboard and USB ALFA)
* connected fine with ath0 ( via command line ) ( all the time the Xwindows was monitoring the connection and message baloons were saying connected / disconnected etc ...
* so I thought maybe it was what ever monitor was running so
* boot TEXT mode ( plain jane BT3 boot no changes )
* connected OK with ath0 ( command line )
* wlan0 I get

Code:

Mar 14 17:00:17 (none) kernel: rtl8187: Card successfully reset Mar 14 17:00:17 (none) kernel: rtl8187: RR:84 BRSR: f1ff Mar 14 17:00:21 (none) kernel: Linking with "AGS_GUEST" rate: 11 MBit Mar 14 17:00:21 (none) kernel: Associated successfully Mar 14 17:00:21 (none) kernel: Using 11 MBit Mar 14 17:01:31 (none) kernel: rtl8187: RX process aborted due to explicit shutdown

why the 'process aborted' happend I dont know ... chcpcd shut the card down ? not sure what that message means ...

here is output of ...

Exact same issue here - Help

Hi guys,

I'm having the exact same problem with my Alfa card. I can crack WEP but can't associate to the AP.
I followed Xploitz instructions exactly but the problem remains.
Anyone else having these problems with BT3 and the Alfa?

Here's my last lines for var\log\messages after trying twice to associate:

Mar 16 21:46:01 (none) kernel: rtl8187: Driver probe completed

Mar 16 21:52:12 (none) kernel: rtl8187: RX process aborted due to explicit shutdown

Any ideas on what is going on?

Thanks
