Wireless Bridge- Two types of wireless bridge connections are allowed:
1. Point-to-Point- The Access Point still functions as the central controller

window will appear. Define the following parameters:
Fragment Threshold:
Fragment Threshold defines a threshold above which the wireless packetwill
be split up, or fragmented. For a fragmented packet, if transmission of part of
it were to be interfered with, only the portion that was successfully
transmitted would need to be re-sent. Throughput will generally be lower for
fragmented packets, since the fixed packet overhead consumes a higher
portion of the RF bandwidth.
RTS Threshold:
The RTS Threshold sets an upper threshold at which point the device will
issue an RTS packet. The RTS (Request To Send) packet is used for the
purpose of avoiding data collisions on the wireless LAN. There are several
trade offs to consider when setting this parameter. Setting this parameter to a
