Workaround:
Enable onboard networking, run # dhclient wlan0, default wireless
connection found and connects on both the onboard and USB connections.
Impact: If something goes wrong with onboard wireless networking, will not be
able to use USB. Concern of possible network issues. Redundant to have to use
onboard and USB connections. Receives better wireless connection via USB than
with onboard.
With Hardy, I was able to leave the onboard wireless OFF, plug in the Wireless
USB adapter, the connection would pick up and connect automatically. Now with
Ibex I have to enable the onboard wireless before the USB wireless will work.
