Chapter 4 Congure the Router in Wireless Router Mode
• WMM - WMM function can guarantee the packets with high-priority messages being
transmitted preferentially.
• AP Isolation - This function isolates all connected wireless stations so that wireless
stations cannot access each other through WLAN.
• Airtime Fairness - This function can improve the overall network performance by
sacrificing a little bit of network time on your slow devices.
• Beacon Interval - Enter a value between 40-1000 milliseconds for Beacon Interval here.
Beacon Interval value determines the time interval of the beacons. The beacons are the
packets sent by the router to synchronize a wireless network. The default value is 100.
• RTS Threshold - Here you can specify the RTS (Request to Send) Threshold. If the packet
is larger than the specified RTS Threshold size, the router will send RTS frames to a
particular receiving station and negotiate the sending of a data frame. The default value is
2346.
• DTIM Interval - This value determines the interval of the Delivery Traffic Indication
Message (DTIM). A DTIM field is a countdown field informing clients of the next window for
listening to broadcast and multicast messages. When the router has buffered broadcast
or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval
value. You can specify the value between 1-255 Beacon Intervals. The default value is 1,
which indicates the DTIM Interval is the same as Beacon Interval.
• Group Key Update Period - Enter a number of seconds (minimum 30) to control the time
interval for the encryption key automatic renewal. The default value is 0, meaning no key
renewal.
4. 4. NAT Forwarding
The router’s NAT (Network Address Translation) feature makes the devices on the LAN
use the same public IP address to communicate on the internet, which protects the local
network by hiding IP addresses of the devices. However, it also brings about the problem
that external hosts cannot initiatively communicate with the specified devices in the local
network.
With the forwarding feature, the router can traverse the isolation of NAT so that clients on
the internet can reach devices on the LAN and realize some specific functions.
The Mercusys router includes four forwarding rules. If two or more rules are set, the priority
of implementation from high to low is Port Forwarding, Port Triggering, UPNP and DMZ.
4. 4. 1. Port Forwarding
When you build up a server in the local network and want to share it on the internet, Port
Forwarding can realize the service and provide it to internet users. At the same time Port
