M SERIES ANALOG CORDED USER GUIDE
3.3 Advanced Settings
Advanced Settings are used to set the advanced wireless functions of the router . It’s advisable that
these operations be performed by a professional, because incorrect settings might reduce the wireless
functions of the router .
BG protection mode: It is favorable for the slow wireless link to successfully connect the gateway under
multiple complex modes . It is Auto by default .
Beacon interval: The gateway sends the Beacon broadcast signal for the synchronization of wireless
network . It represents the frequency of sending the Beacon broadcast signal . The default is 100 ms in
the scope of 20–999 ms .
Data beacon ratio (traffic indication message): The value is between 1 and 255, which specifies the
interval of delivery traffic indication message (DTIM) . The DTIM is a countdown job telling the next client
window to receive the broadcast and multicast . When the gateway has stored the broadcast and multicast
message for relevant clients, it will carry the message of next DTIM interval in Beacon . When the client
hears the Beacon signal, he will receive the broadcast and multicast message . The default is 1 .
Dividing the boundary: Specify the fragment threshold for a data packet . When the length of a data
packet exceeds the fragment threshold, it will be automatically divided into several data packets . The
excessive data packets will result in the reduction of network performance . Therefore, the fragment
threshold shall not be set too low . The default is 2346 .
Transmission request limit: Specify the RTS (Request to Send) threshold for a data packet . When
the length of a data packet exceeds the RTS threshold, the gateway will send RTS to the destination
