between Access Points. If a Client receives a beacon from an AP with a
stronger signal than the current AP (providing SSID is the same and capability information are
compatible), it may disconnect from the first AP and establish a link with the second AP. This
functionality permits a client to have mobility whilst maintaining a link with the most suitable AP.

The Ethernet RJ45 port incorporates two indication LEDs. The LINK LED comes on when there is
a connection on the Ethernet port, and will blink off briefly when activity is detected on the Ethernet
