I just bought a blueproton realtek rtl8187 usb wifi adapter, but I cannot seem to get it to work in Backtrack 4 running in vmware player. I know that you have to run the command "/etc/init.d/networking start" but there are errors such as "no DHCPOFFERS received" and "No working leases in persistent database - sleeping." These also come up when I try "ifconfig wlan0 up" and "dhclient wlan0." When I run the command "airmon-ng," my wireless adapter comes up there recognized as wlan0. It says the chipset is "RTL8187" and the driver is "rtl8187 - [phy1]." When I run "airodump-ng wlan0" it says "device or resource busy." What should I do to get this to work? And, this is my first post on these forums. Thanks
