How to switch from OPEN wifi to a secured wifi unit?
Looking to switch my Apple airport extreme from an open wifi to a more secured wifi unit , cause my niece who i bought the unit for did not know how to switch the unit from an OPEN wifi to a more secured Apple wifi at the time and i'm trying to secure the apple airport extreme model A1143 , so we don't have unwanted users to use the free home wifi, only user's with the password for the unit..!!!
What is the procedure to switch it?? Wifi or hardline from a PC computer ??
Is this a good question?
