Absolutely unexpected to see this. The ASUS WL-167g was produced in three
different revisions (v1/v2/v3), all of them using chips/chipsets that are
free software incompatible. My advice is to get rid of it since it only
supports the old IEEE 802.11g standard, whose maximum theoretical speed is
about 54Mbps, and also because of the aforementioned fact, and keep the
TL-WN722N model. If you want something better, my recent comparison shows,
that the best in latest generation free software compatible wireless adapter
can be achieved with the TP-Link's TL-WN822N model.
OT: Can I ask you to make a photo of the front and back side of your ASUS
WL-167G adapter so I can attach those pictures to their respective WikiDevi
page (of course only with your permission to do so)?
P.S.: I have some more ideas what you can do in order to force the adapter to
work. Hold on for some time, I'll let you know.
