I've made some changes to the CDS wireless access points, they will now only allow a certain list of known CDS computers to connect (this is in addition to the authentication already in place).  If you come across a *CDS* computer that is not working and you think it should be, let me know.  In addition, 802.11n data rates are enabled on all of the access points now that all the old OS X installs that caused issues with these data rates have been removed.  This should make things a little faster for wireless clients on the network.
