Problem with USB wireless antenna in BackTrack 5
#1
Sorry to bother but this is the only way to get to you and ask you a question.

I have problem with my USB wireless antenna in BackTrack 5. I have REALTEK RTL8187L wireless USB antenna and I do not know how to start?
When I type ''start networking'' show me ''networking stop/waiting''.

When I type ''airmon-ng'' show me
Interface Chipset Driver

wlan1 Realtek RTL8187L rtl8187 - [phy0]

When I type ''iwconfig'' show me

lo no wireless extensions.

eth1 no wireless extensions.

wlan1 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off

When I type ''rfkill list'' show me
Wireles lan
soft blocked: no
hard blocked: yes

I started etc/init.d/wicd start

When type ''airmon-ng start wlan1'' show me

Found 1 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

PID Name
813 dhclient3

Interface Chipset Driver

wlan1 Realtek RTL8187L rtl8187 - [phy0]SIOCSIFFLAGS: Unknown error 132

(monitor mode enabled on mon0)
Then I type ''airodump-ng mon0'' and show me
Interface mono0:
ioctl(SIOCGIFINDEX) failed: No such device
root@bt:~# airodump-ng mon0
ioctl(SIOCSIFFLAGS) failed: Unknown error 132
root@bt:~# lsusb

Bus 001 Device 002: ID 1b75:8187
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

What I to do??
sorry if I reposting but I need help.

I see there is 1 process still running in your wlan1.
You must kill the PID number (813)

please try this command:
# kill 813
