1Configure Basic Wireless Parameters

This section allows you to configure wireless basic parameters, such as 802.11 mode, Transmit Power, and data rates.

Go to the Wireless Page. In the Basic Wireless Settings section, configure the basic wireless settings and click Apply. Then click Save.

Figure 1-1 Configuring Basic Wireless Parameters

Mode

Select the protocol standard used in the wireless network. With a frequency band of 2.4GHz, CPE210/CPE220/WBS210 supports five wireless modes: 802.11b, 802.11g, 802.11n, 802.11b/g and 802.11b/g/n. We recommend you to set the mode as 11b/g/n mixed, and all of 802.11b, 802.11g and 802.11n wireless stations can connect to the device. CPE610/CPE510/CPE520/WBS510 has a frequency band of 5GHz, supporting 802.11a, 802.11n and 802.11a/n modes. We recommend you to set the mode as 11a/n, allowing both 802.11a and 802.11n wireless stations to access the device.

Channel Width

Select the channel width of this device. Options include 5MHz, 8MHz, 10MHz, 20MHz, 30MHz, 40MHz and 20/40MHz (the device automatically selects 20MHz/40MHz, and 20MHz will be used if 40MHz is not available). You can select corresponding channel width according to whether their devices support it. According to IEEE 802.11n standard, using a channel width of 40MHz can increase wireless throughput. However, you may need choose lower bandwidth due to the following reasons:

Increase the available number of channels within the limited total bandwidth.

To avoid interference from overlapping channels occupied by other devices in the environment.

Lower bandwidth can concentrate higher transmit power, increasing stability of wireless links over long distances.

Subject to the channel width of root AP in Client/ Bridge/ Repeater/ Client Router operation modes.

Max TX Rate

Set the maximum transmit data rate.

Channel/Frequency

Select appropriate channel used by this device to improve wireless performance. 1/2412MHz refers to Channel 1 and the frequency is 2412MHz. This setting is only available in Access Point mode and AP Router mode.

CPE210/CPE220/WBS210 is a device with a frequency of 2.4GHz and CPE610/CPE510/CPE520/WBS510 has a frequency of 5GHz. We highly recommend that you use the Spectrum Analysis tool to select a proper channel.

Antenna Gain

Antenna Gain is only available in WBS products. Enter the antenna gain value according to the antennas and the value ranges from 0 to 30dBi. It can work together with the transmit power to improve the transmit signal quality.

Transmit Power

Specify the transmit power of the device. You can use the slider or manually enter the transmit power value. For WBS210 and WBS510, the maximum transmit power varies according to the antenna gain value.

In most scenarios, it is unnecessary to select the maximum transmit power. Selecting larger transmit power than your need may cause interference to neighborhood. Also it consumes more power and will reduce longevity of the device. Select appropriate transmit power to achieve the best performance. You can use the Speed Test tool to find the best performance

MAXtream

Enable or disable the MAXtream function. This function is only available in Access Point mode and AP Router mode. MAXtream is a TP-Link proprietary technology. It is based on TDMA (Time Division Multiple Access) so that data streams are transmitted in their own time slots. MAXtream aims to maximize throughput and minimize latency. “Hidden nodes” problem can also be eliminated with MAXtream enabled.

MAXtream Technology is only compatible with Pharos series products. Working with products from other manufacturer will cause network fault.

MAXtream Station Mode

MAXtream Station Mode is available in Client mode, Bridge mode and AP Client Router mode with the wireless AP settings disabled.

Auto Adjust: The device will choose the MAXtream station mode automatically.

Latency First: Set the MAXtream station mode as Latency First and the time sensitive stream such as VoIP will take precedence in MAXtream system.

Throughput First: Set the MAXtream station mode as Throughput First and the stream that needs high throughput such as online games will take precedence in MAXtream system.

2Configure Wireless Client Parameters

Note:

Wireless Client Settings submenu is only available in Client, Repeater, Bridge and AP client Router (WISP client) mode.

In this section, you can configure wireless client parameters used for the connection with the root AP.

Figure 2-1 Configuring Wireless Client Settings

1)Go to the Wireless Page. In the Wireless Client Settings section, configure the following parameters.

WDS

Displays the status of the WDS (Wireless distribution System) function. WDS is a communication system among multiple wireless networks . It is established between APs through wireless connection. WDS is used to during the connection between the device and the root AP.

Enable: Forward data frames to use four address fields.

Disable: Forward data frames to use three address fields.

Auto: The device automatically negotiates the wireless data frame structure (three or four address fields) with the root AP. The selection of Auto is recommended.

2)Specify the security mode. Make sure the Security mode and the related parameters are the same as the upstream wireless network’s.

»None

Select this option if the root AP has no encryption. When connecting to the root AP, it’s no need to enter a password to access the wireless network.

»WEP

WEP (Wired Equivalent Privacy) is a traditional encryption method. It has been proved that WEP has security flaws and can easily be cracked, so WEP is rarely used in normal wireless network. Select this option if the security mode of the root AP is WEP.

Note:

WEP is not supported in 802.11n mode or 802.11ac mode. If WEP is applied in 802.11n, 802.11 ac or 802.11n/ac mixed mode, the clients may not be able to access the wireless network. If WEP is applied in 802.11b/g/n mode (2.4GHz) or 802.11a/n (5GHz), the device may work at a low transmission rate.

3)Click Save and click Apply. Then click Save.

6Configure Advanced Wireless Parameters

This section is used to specify the advanced wireless parameters, such as Beacon Interval, RTS threshold and DIM Interval.

Go to the Wireless page. In the Advanced Wireless Settings section, specify the following parameters and click Apply. Then click Save.

Figure 6-1 Configuring Advanced Wireless Parameters

Distance Setting

Specify the distance between AP and Station. If this device serves as a client, the value is the distance between this device and the root AP. If this device serves as an AP, the value is the distance between the farthest client and this AP.

You can manually enter the value or enable the Auto option.

Manual: Enter the distance manually in the input box. The value is limited to 0-200km, and we recommend you set the value to 110% of the real distance.

Auto (Only works within 0-xx km): Check the Auto option, then the system will dynamically detect the distance. This function is available only when the distance is less than xx kilometers. The value xx varies according to the channel width you set. CPE210 does not support this option.

The distance value will be converted to a corresponding ACK timeout value, and the ACK timeout value will influence the throughput performance to a large extent.

Beacon Interval

Specify the beacon interval for the device. Beacons are transmitted periodically by the device to announce the presence of a wireless network for the clients. Beacon Interval value determines the time interval of the beacons sent by the device. You can specify a value from 40 to 1,000. The default value is 100.

RTS Threshold

Specify the RTS threshold for the device.

RTS/CTS (Request to Send/Clear to Send) is used to improve the data transmission efficiency of the network with hidden nodes, especially when there are lots of large packets to be transmitted.

When the size of a data packet is larger than the RTS Threshold, the RTS/CTS mechanism will be activated. With this mechanism activated, before sending a data packet, the client will send an RTS packet to the device to request data transmitting. And then the device will send CTS packet to inform other clients to delay their data transmitting. In this way, packet collisions can be avoided.

For a busy network with hidden nodes, a low threshold value will help reduce interference and packet collisions. But for a not-so-busy network, a too low threshold value will cause bandwidth wasting and reduce the data throughput. The recommended and default value is 2346 bytes.

Fragmentation Threshold

Specify the fragmentation threshold for packets.

The fragmentation function can limit the size of packets transmitted over the network. If the size of a packet exceeds the Fragmentation Threshold, the fragmentation function is activated and the packet will be fragmented into several packets.

Fragmentation helps improve network performance if properly configured. However, a too low fragmentation threshold may result in poor wireless performance caused by the extra work of dividing up and reassembling of frames and increased message traffic. The recommended and default value is 2346 bytes.

DTM Interval

Specify the DTM (Delivery Traffic Indication Message) Interval for the device.

The DTIM is contained in some Beacon frames. It indicates whether the device has buffered data for client devices. The DTIM Period indicates how often the clients served by this device should check for buffered data still on the device awaiting pickup.

You can specify the value between 1-255 Beacon Intervals. The default value is 1, indicating that clients check for buffered data at every beacon. An excessive DTIM interval may reduce the performance of multicast applications, so we recommend you keep the default value.

AP Isolation

Enable or disable AP Isolation. With this feature enabled, the clients can not communicate with each other directly.

AP Isolation is not available in Client mode.

Short GI

Enable or disable Short GI.

Propagation delays often occurs in data transmission process and influence the capability of the wireless network. It can result from multiple factors, such as multipath effect. GI (Guard Interval) is intended to solve the problem based on delays, and Short GI is used to improve the throughput of the wireless network based on the GI in the environment with small delays.

When the delays are small. When Short GI is enabled, the guard interval will be set as 400ns and this function will boost the performance about 11%. In the with serious multipath time delay. Short GI function will reduce the throughput instead of improving it.

Wi-Fi Multimedia (WMM)

Enable or disable WMM. With WMM enabled, the system will prioritize traffic according to the data type when forwarding data. Time-dependent traffic, such as video or audio packets, gets a higher priority than normal traffic.

We recommend you enable this function when you are running the video or audio application.

QoS

Enable or disable QoS. The QoS function improves the transmission performance of video or audio traffic by optimizing the scheduling policy between the AP and the clients.
