Well, the point here was that trying to run anything nl80211-based (like
'iw') on Centos 5 is simply not expected to work, because Centos 5 is
too old to support most of what 'iw' needs, both compile-time stuff and
likely runtime stuff.  The 2.6.18 kernel that Centos 5 has was
originally released in 2006, and that was *long* before any
nl80211-based wifi stuff was usable.  Which means iw is quite unlikely
to ever work there.

RHEL 6 (or Centos 6) have good nl80211 support and thus would be  much
more likely to work with 'iw'.
