The administrator can tune the following parameters to improve network communication performance if a poor connection occurs.  Advanced Wireless Settings Page  RTS Threshold: Enter a value between 1 and 2346. RTS (Request to Send) Threshold determines the packet size at which the system issues a request to send (RTS) before sending the fragment to prevent the hidden node problem. The RTS mechanism will be activated if the data size exceeds the value provided. A lower RTS Threshold setting can be useful in areas where many client devices are associating with the AP or in areas where the clients are far apart and can detect only the AP but not each other.   Fragmentation Threshold: Enter a value between 256 and 2346. The default is 2346. A packet size larger than this threshold will be fragmented (sent with several pieces instead of one chunk) before transmission. A smaller value results in smaller frames but allows a larger number of frames in transmission. A lower Fragment Threshold setting can be useful in areas where communication is poor or disturbed by a serious amount of radio interference.  DTIM Period: Input the DTIM Interval that is generated within the periodic beacon at a specified frequency. Higher DTIM will allow the wireless client to save more energy, but the throughput will be lowered.  Broadcast SSID: Disabling this function will stop the system from broadcasting its SSID. If broadcast of the SSID is disabled, only devices that have the correct SSID can connect to the system.  Wireless Station Isolation: By enabling this function, all stations associated with the system are isolated and can only communicate with the system.
                                                                         User’s Manual   Light Industrial AP ENGLISH 61 Copyright © NEXCOM, INC.  WMM: The default is Disable. Wi-Fi Multimedia (WMM) is a Quality of Service (QoS) feature that prioritizes wireless data packets based on four access categories: voice, video, best effort, and background. Applications without WMM and applications that do not require QoS are assigned to the best-effort category, which receives a lower priority than that of voice and video.  Therefore, WMM decides which data streams are more important and assigns them a higher traffic priority. This option works with WMM-capable clients only.  <To receive the benefits of WMM QoS> ▬ The application must support WMM. ▬ WMM shall be enabled on the Access Point. ▬ WMM shall be enabled in the wireless adapter on client’s computer.  IAPP: IAPP (Inter Access Point Protocol) is a protocol by which access points share information about the stations connected to them. When this function is enabled, the system will automatically broadcast information of associated wireless stations to its peer access points. This will help wireless stations roam smoothly among IAPP-enabled access points in the same wireless LAN.  IGMP Snooping: When IGMP snooping is enabled, IGMP packets are transferred via the Access Point’s network interface and the IP multicast host. Registration information is recorded and sorted into multicast groups. The internal switch can then intelligently forward traffic only to those ports that request multicast traffic. Adversely, without IGMP snooping, multicast traffic is treated like broadcast traffic, with packets forwarded to all ports causing network inefficiencies.  Multicast/Broadcast Rate: Bandwidth configuration for multicast/broadcast packets. If your wireless clients require a larger or smaller bandwidth for sending multicast/ broadcast packets, the administrator can customize the Access Point’s multicast/ broadcast bandwidth here.  Management Frame Rate: This feature controls the bandwidth for Management Frames. The higher the rate it, the shorter range the transmission covers
                                                                         User’s Manual   Light Industrial AP ENGLISH 62 Copyright © NEXCOM, INC. 7.2.7 Access Control  On this page, the network administrator can restrict the total number of clients connected to the Access Point, as well as specify particular MAC addresses that can or cannot access the device.  Access Control Settings Page  Maximum Number of Clients The NEXCOM Access Point supports various methods of authenticating clients for wireless LAN access. The default policy is unlimited access without any authentication requirement.  To restrict the station number of wireless connections, simply change the Maximum Number of Stations to a desired number.  For example, when the number of stations is set to 20, only 20 stations are allowed to connect to the specified VAP.
                                                                         User’s Manual   Light Industrial AP ENGLISH 63 Copyright © NEXCOM, INC.  Access Control Type The administrator can restrict the wireless access of client devices based on their MAC addresses.   Disable Access Control: When Disable is selected, there is no restriction for client devices to access the system.  MAC ACL Allow List: When selecting MAC ACL Allow List, only the client devices (identified by their MAC addresses) listed in the Allow List (“allowed MAC addresses”)are granted access to the system. The administrator can temporarily block any allowed MAC address by checking Disable, until the administrator re-Enables the listed MAC.  MAC Allow List  Note: An empty Allow List means that there is no allowed MAC address.  Make sure at least the MAC of the management system is included (e.g. network administrator’s computer)

The ARP table maintained by the AP will be used as a look up table upon receipt of ARP request from AP uplink. Adversely, without Proxy ARP, ARP request is broadcasted down into the AP’s wireless network causing network inefficiencies. o Force DHCP option when enabled, the AP only learns MAC/IP pair information through DHCP packets. Since devices configured with static IP address does not send DHCP traffic, any clients with static IP address will be blocked from internet access unless its MAC/IP pair is listed and enabled on the Static Trust List. o Trust List Broadcast can be enabled to let other APs (with L2 firewall feature) learn the trusted MAC/IP pairs to issue ARP requests. o Static Trust List can be used to add MAC or MAC/IP pairs of devices that are trusted to issue ARP request. Other network nodes can still send their ARP requests; however, if their IP appears on the static list (with different MAC), their ARP requests will be dropped to prevent eavesdropping.
