8.1 Basic
8.1.1 Overview
This module enables you to set SSID-related parameters of the AP. However, you are only recommended to change the SSID, security mode but retain the other default settings. To access the configuration page, click Wireless > Basic.
Broadcast SSID
When the AP broadcasts an SSID, wireless devices nearby can detect the SSID. When this parameter is set to Disable, the AP does not broadcast the SSID so that nearby wireless devices cannot detect the SSID. In this case, you need to enter the SSID manually on your wireless devices to connect to the WiFi network corresponding to the SSID. To some extent, disabling broadcasting SSID enhances the security of the WiFi network.
However, even though Broadcast SSID is set to Disable, a hacker can still connect to the corresponding WiFi network if he/she manages to obtain the SSID by other means.
34
Wireless Access Point User Guide
Isolate Client
This parameter implements a function similar to the VLAN function for wired networks. It isolates the wireless devices connected to the same WiFi network, so that the wireless devices can access only the wired network connected to the AP. You can apply this function to hotspot setup in public such as hotels and airports to improve network security.
WMF
The number of wireless devices keeps increasing currently, but wired and wireless bandwidth resources are limited. Therefore, the multicast technology, which enables single-point data transmission and multi-point data reception, has been widely used in networks in order to reduce bandwidth requirements and prevent network congestion.
Nevertheless, if a large number of devices are connected to a wireless interface of a WiFi network and multicast data is intended for only one of the devices, the data is still sent to all the devices, which increases unnecessary wireless resource usage and may lead to wireless channel congestion. In addition, multicast stream forwarding over an 802.11 network is not secure, either.
The WMF function of the AP converts multicast traffic into unicast traffic and forwards the traffic to the multicast traffic destination in the WiFi network, helping save wireless resources, ensuring reliable transmission, and reducing delays.
Max. Number of Clients
This parameter specifies the maximum number of devices that can connect to the WiFi network corresponding to an SSID. If the number is reached, the WiFi network rejects new connection requests from devices. This limit helps balance load among APs.
Chinese SSID Encoding
It specifies the encoding format of Chinese SSIDs, which consists of UTF-8 (default) and GB2312. This setting is effective only when an SSID contains Chinese characters. If you want your Chinese SSID to be displayed properly, select the encoding format supported by you wireless devices.
Security Mode
A WiFi network uses radio open to the public as its data transmission medium. If the WiFi network is not protected by necessary measures, any device can connect to the network to access unprotected data over the network or the resources of the network. To ensure communication security, transmission links of WiFi network must be encrypted.
The AP supports various security modes for network encryption, including None, WEP, WPA-PSK, WPA2-PSK, Mixed WPA /WPA 2-PSK, WPA , and WPA2 .
None
It indicates that any wireless device can connect to the WiFi network. This option is not recommended because it leads to network insecurity.
WEP
It uses a static key to encrypt all exchanged data, and ensures that a WiFi LAN has the same level of
35
Wireless Access Point User Guide
security as a wired LAN. However, data encrypted based on WEP can be easily cracked. In addition, WEP supports a maximum WiFi network throughput of only 54 Mbps. Therefore, this security mode is not recommended.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK
They belong to pre-shared key or personal key modes, where Mixed WPA/WPA2-PSK supports both WPA-PSK and WPA2-PSK.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK adopt a pre-shared key for authentication, while the AP generates another key for data encryption. This prevents the vulnerability caused by static WEP keys, and makes the three security modes suitable for ensuring security of home WiFi networks. Nevertheless, because the initial pre-shared key for authentication is manually set and all devices use the same key to connect to the same AP, the key may be disclosed unexpectedly. This makes the security modes not suitable for scenarios where high security is required.
WPA and WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance puts forward WPA and WPA2, which use 802.1x to authenticate devices and generate data encryption–oriented root keys. WPA and WPA2 use the root keys to replace the pre-shared keys that set manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate devices and the login information of a device is managed by the device. This effectively reduces the probability of information leakage. In addition, each time a device connects to an AP that adopts the WPA or WPA2 security mode, the RADIUS server generates a data encryption key and assigns it to the device, which makes it difficult for attackers to obtain the key. These features of WPA and WPA2 help increase network security significantly, making WPA and WPA2 the preferred security modes of WiFi networks that require high security.
8.1.2 Changing the basic settings
To change the basic settings of an SSID, perform the following procedure:
1. Choose Wireless > Basic.
2. Select the SSID from the SSID drop-down list box.

59
Wireless Access Point User Guide
Parameter Description
20/40: It indicates that the AP automatically adjusts its channel bandwidth to
20 MHz or 40 MHz according to the ambient environment.
Extension Channel It specifies the wireless extension channel of the AP.
Lock Channel
It is used to lock the channel settings of the AP. If this parameter is selected, channel settings including Country/Region, Network Mode, Channel, Channel Bandwidth, and Extension Channel cannot be changed.
Transmit Power
It specifies the transmit power of the AP. The default value is 8 dBm. If the AP has a higher transmit power, its WiFi coverage is wider. However, reasonably decreasing the transmit power will improve the AP’s WiFi network performance and security.
Lock Power
It specifies whether the current transmit power settings of the AP can be changed. If you tick this box, the current transmit power could not be changed.
Preamble
It specifies a group of bits located at the beginning of a packet, according to which the receiver of the packet can perform synchronization and prepare for receiving data.

Parameter description
Parameter Description
Beacon Interval
It specifies the interval for transmitting the Beacon frame. The value range is 100 to 999, with a unit millisecond.
The Beacon frame is transmitted at the specified interval to announce the presence of a wireless network. Generally, a smaller interval enables wireless devices to connect to the AP more quickly, while a larger interval ensures higher data transmission speed for the AP.
Fragment Threshold
It specifies the threshold of a fragment. The value range is 256 to 2346, with a unit byte.
Fragmenting is a process that divides a frame into several fragments, which are transmitted and acknowledged separately. If the size of a frame exceeds this threshold, the frame is fragmented.
In an environment of high error rate, you can reduce the threshold to enable the AP to
resend only the fragments that have not been sent successfully, so as to increase the
61
Wireless Access Point User Guide
Parameter Description
frame throughput.
In an environment without interference, you can increase the threshold to reduce the number of acknowledgement times, so as to increase the frame throughput.
RTS Threshold
It specifies the frame length threshold for triggering the RTS/CTS mechanism.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce conflicts. The value range is 1 to 2347, with a unit byte.
Set the RTS threshold based on the actual situation. An excessively small value increases the RTS frame transmission frequency and bandwidth requirement. A higher RTS frame transmission frequency enables a WiFi network to recover from conflicts quicker. For a WiFi network with high user density, you can reduce this threshold for reducing conflicts. The RTS mechanism requires some network bandwidth. Therefore, it is triggered only when frames exceed this threshold.
DTIM Interval
It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM) frame. The value range is 1 to 255, with a unit Beacon.
A countdown starts from this value. The AP transmits broadcast and multicast frames in its cache only when the countdown reaches zero.
For example, if DTIM Interval is set to 1, the AP transmits all cached frames after each beacon frame is transmitted.
Min. RSSI Threshold
It specifies whether to enable the Min. RSSI Threshold function. After you enabled this function, a minimum strength of received signals acceptable to the AP should be set. If the strength of the signals transmitted by a wireless device is weaker than this threshold, the wireless device cannot connect to the AP.
If there are multiple APs, an appropriate Min. RSSI Threshold ensures that wireless devices can connect to the AP’ WiFi networks with strong signals.
Interference Mitigation
Select an interference mitigation mode for your AP.
0: The energy detection mechanism is disabled.
1: The energy detection mechanism is enabled. When the received signal strength is weaker than -70 dBm, this device stops transmitting data, so as to prevent packet loss due to interference.
2: The energy detection mechanism is enabled. When the received signal strength is weaker than -50 dBm, this device stops transmitting data, so as to prevent packet loss due to interference.
3: The energy detection mechanism is enabled. When the received signal strength is weaker than -70 dBm, this device automatically switches to a better channel.
APSD
It enables the AP to reduce power consumption after a specified period during which no traffic is transmitted or received by the AP. By default, it is disabled.
Client Timeout Interval
It specifies the wireless device disconnection interval of the AP. The AP disconnects a wireless device if no traffic is transmitted or received by the wireless client within the interval.
Basic Rate Sets

8.5 WMM Setup
8.5.1 Overview
802.11 networks offer wireless access services based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) channel competition mechanism, which allows all wireless devices to fairly compete for channels. All the services implemented over WiFi networks share the same channel competition parameters. Nevertheless, different services usually have different requirements for bandwidth, delay, and jitter. This requires wireless networks to offer accessibility based on the services implemented over the networks.
WMM is a wireless QoS protocol used to ensure that packets with high priorities are transmitted first. This ensures better experience of voice and video service over WiFi networks.
WMM involves the following terms:
Enhanced Distributed Channel Access (EDCA): It is a channel competition mechanism to ensure
that packets with higher priorities are assigned more bandwidth and transmitted earlier.
Access Category (AC): The WMM mechanism divides WLAN traffic by priority in descending order
into the AC-VO (voice stream), AC-VI (video stream), AC-BE (best effort), and AC-BK (background) access categories. The access categories use queues with different priorities to send packets. The WMM mechanism ensures that packets in queues with higher priorities have more opportunities to access channels.
According to the 802.11 protocol family, all devices listen on a channel before using the channel to send data. If the channel stays idle for or longer than a specified period, the devices wait a random backoff period within the contention window. The device whose backoff period expires first can use the channel. The 802.11 protocol family applies the same backoff period and contention window to all devices across a network to ensure that the devices have the same channel contention opportunity.
EDCA Parameters
WMM changes the contention mechanism of 802.11 networks by dividing packets into four ACs, among which the ACs with higher priorities have more opportunities to access channels. The ACs help achieve different service levels.
WMM assigns each AC a set of EDCA parameters for channel contention, including:
Arbitration Inter Frame Spacing Number (AIFSN): Different from the fixed distributed inter-frame
spacing (DIFS) specified in the 802.11 protocol family, AIFSN varies across ACs. A greater AIFSN indicates a longer backoff period. See AIFS in the following figure.
Contention window minimum (CWmin) and contention window maximum (CWmax) specify the
average backoff period. The period increases along with these two values. See the backoff slots in the following figure.
Transmission Opportunity (TXOP): It specifies the maximum channel use duration after successful
channel contention. The duration increases along with this value. The value 0 indicates that a device can send only one packet through a channel after winning contention for the channel.
64
Wireless Access Point User Guide
ACK Policies
WMM specifies the Normal ACK and No ACK policies.
According to the No ACK policy, no ACK packet is used during wireless packet transmission to
acknowledge packet reception. This policy is applicable to scenarios where interference is mild and can effectively improve transmission efficiency. In case of strong interference, lost packets are not sent again if this policy is adopted. This leads a higher packet loss rate and reduces the overall performance.
According to the Normal ACK policy, each time a receiver receives a packet, it sends back an ACK
packet to acknowledge packet reception.
8.5.2 Changing the WMM Settings
By default, the WMM function of the AP is enabled and the Optimized For Capacity mode is adopted. The following procedures describe how to set the WMM settings:
1. Choose Wireless > WMM Setup.

9 SNMP
9.1 Overview
The Simple Network Management Protocol (SNMP) is the most widely used network management protocol in TCP/IP networks. SNMP enables you to remotely manage all your network devices compliant with this protocol, such as monitoring the network status, changing network device settings, and receiving network event alarms.
SNMP supports managing devices bought from various vendors automatically, regardless of physical differences among the devices.
9.1.1 SNMP management framework
The SNMP management framework consists of SNMP manager, SNMP agent, and Management Information Base (MIB).
SNMP manager: It is a system that controls and monitors network nodes using the SNMP protocol.
Network Management System (NMS) is the most widely used SNMP manager in network environments. An NMS can be a dedicated network management server, or an application that implements management functions in a network device.
SNMP agent: It is a software module in a managed device. This module is used to manage data
about the device and report the management data to an SNMP manager.
MIB: It is a collection of managed objects, defining a series of attributes of managed objects,
including names, access permissions, and data types of objects. Each SNMP agent has its own MIB. An SNMP manager can read and/or write objects in the MIB based on the permissions assigned to the SNMP manager.
An SNMP manager manages SNMP agents in an SNMP network. The SNMP manager exchanges management information with the SNMP agents using the SNMP protocol.
9.1.2 Basic SNMP operations
The AP supports the following basic SNMP operations:
Get: An SNMP manager performs this operation to query the SNMP agent of the AP for values of
one or more objects.
Set: An SNMP manager performs this operation to set values of one or more objects in the MIB of
the SNMP agent of the AP.
75
Wireless Access Point User Guide
9.1.3 SNMP protocol version
The AP is compatible with SNMP V1 and SNMP V2C and adopts the community authentication mechanism. Community name is used to define the relationship between an SNMP agent and an SNMP manager. If the community name contained in an SNMP packet is rejected by a device, the packet is discarded. A community name functions as a password to control SNMP agent access attempts of SNMP managers.
SNMP V2C is compatible with SNMP V1 and provides more functions than SNMP V1. Compared with SNMP V1, SNMP V2C supports more operations (GetBulk and InformRequest) and data types (such as Counter64), and provides more error codes for better distinguishing errors.
9.1.4 MIB introduction
An MIB adopts a tree structure. The nodes of the tree indicate managed objects. A path consisting of digits and starting from the root can be used to uniquely identify a node. This path is calling an object identifier (OID). The following figure shows the structure of an MIB. In the figure, the OID of A is
1.3.6.1.2.1.1, whereas the OID of B is 1.3.6.1.2.1.2.
