screens, the message file may be missing.
4. Select a Roaming Mode. If you want the terminal to ping an AP, but roam between 
APs as you move around, select Roaming Enabled. If you want to ping a specific 
AP, select that AP identifier from the list. If more APs are in range than can fit on one 
screen, then the last selection will be More. Selecting this will present more available 
APs for selection.
Figure A-4 shows a Roaming Enabled option, followed by a list of AP identifiers. For 
each AP identifier, bb represents the AP identifier (or BSS identifier) and 
eeeeeeeeeeee represents the 48-bit MAC address of the AP in hexadecimal 
notation.
