But i may be jumping to a misunderstanding.  If the network is really called CPSWIRELESS then it is the old simple WEP-key one; and my last remark about her signing in to the wi-fi is irrelevant.  (Similarly with your point about PEAP and certificates.)  Those come into play if the network is called just CPS.    (But the CPSWIRELESS utility IS the right thing to use for setting that up.)
