2-2-1-3 Add an Access Point to Profile
If you will connect to some specific wireless access point frequently, you can
add their information to the profile. Just like the telephone directory, the profile
saves all information of access points, and you can recall them anytime you
wish to establish connection.
You can add a found access point to profile, or access to Profile section to
input all information of an access point by yourself.
