I can confirm that this procedure still works just fine in BT3F using the Alfa 500mw. Make sure that you empty your dhcpc folder before trying to connect to a new network, and if you still experience any problems reload the r8187 drivers and kill any running dhcpcd process. The commands for this are as shown below.
Code:dhcpcd -k wlanx rm /etc/dhcpc/* rmmod r8187 modprobe r8187
