Parameter Description 

Fragement 

The value defines the maximum size of packets, any packet size 

larger than the value will be fragmented. If you have decreased 

this value and experience high packet error rates, you can 

increase it again, but it will likely decrease overall network 

performance. Select a setting within a range of 256 to 2346 bytes. 

Minor change is recommended. 

 

 

RTS / CTS 

Minimum packet size required for an RTS/CTS (Request To 

Send/Clear to Send). For packets smaller than this threshold, an 

RTS/CTS is not sent and the packet is transmitted directly to the 

WLAN. Select a setting within a range of 0 to 2347 bytes. Minor 

change is recommended. 

 

 

Preamble 

The preamble defines the length of the CRC block for 

communication among the wireless networks. There are two 

modes including Long and Short. High network traffic areas should 

use the shorter preamble type. 

 

 

MAC Address Filter 

This AP can protect from the unauthorized users by MAC Address 

filtering. Please refer to Section 6.5.3. 

 

 

Bridge Adapter 

Wireless adapters connect to the AP can access to the wired 

network through the bridge adapter. You can select an Ethernet 

adapter in the list be the bridge between the wireless and wired 

networks.
