Hello everyone, I'm quite new on back track and I'm having a problem with my wireless Asus WL-167g v2 USB. First when I tried to monitor I receive the following error :

ioctl(SIOCSIWMODE) failed: Device or resource busy
ARP linktype is set to 1 (Ethernet) – expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make
sure RFMON is enabled: run ‘airmon-ng start wlan0 <#>’
Sysfs injection support was not found either

But I managed to fix it.

However, when I'm monitoring using the USB on a VMware machine using Back track 4, it finds only WAP networks and not a single WEP network . I believe it might be some problem with the USB configuration because when I run back track 4 from de CD it finds all networks including wep encryption and allows me to complete the password hacking.

What should I do to find also networks using WEP on Back track 4 VMware machine? can anyone help me on this one?

Thanks a lot!!
