• Fragmentation Threshold – frame fragmentation threshold, bytes. The parameter takes values 256-2346, by default – 2346;
• RTS Threshold – after what quantity of bytes the Request to Send will be sent. Decreasing of the parameter's value might improve access point operation when there are a lot of clients connected. However, decreasing of the parameter's value will reduce general bandwidth of wireless network. The parameter takes values from 0 to 2347, by default – 2347;
• Beacon Interval, ms – beacon frames transmission period. The frames are sent to detect access points. The parameter takes values from 20 to 2000 ms, by default – 100 ms;
• Aggregation – enable support for AMPDU/AMSDU;
• Short Guard interval – support for shortened guard interval. 400 ns interval is used (instead of 800 ns).
• STBC – Soace-Time Block Coding method dedicated to improve data transmission reliability. When checked, the device transmits one data flow through several antennas. When unchecked, the device does not transmit one data flow through several antennas;

The device is capable to assign IP addresses and other parameters required to the Internet access to computers connected to LAN interface through DHCP (Dynamic Host Configuration Protocol). The use of DHCP allows to avoid manual configuration of TCP/IP.

LAN:

• IP address – IP address of the device in a local network;
• Netmask – subnetmask in local network.

...

In the MAC address Management submenu, you may set MAC address of the device's WAN interface.

NAT (Network Address Translation) mode allows to modify IP addresses and network ports of IP packets. Port forwarding is necessary when TCP/UDP connection with local PC (connected to LAN interface) is established via external network. The settings menu allows to set rules which permit packets transmission from external network to specified address in a local network, i.e. to establish connection. Port forwarding is also necessary when using torrent and p2p services. To implement the configuration, find TCP/UDP ports used by torrent or p2p clients in settings and set them for corresponding port forwarding rules to a PC IP address.
