Support Mesh Network

The message, information, and data can be transferred via wireless connection among VigorAP 912C devices without by using Ethernet cables. It can reduce the construction cost and eliminate the trouble of wiring. Therefore, mesh AP is suitable for outdoor activities, or meetings.

In short, VigorAP with mesh function has the following benefits:

 In the traditional wireless network, users must choose the best signal source manually from

various SSIDs. The mesh AP can find out the best route automatically. Besides, if any one of the mesh AP devices disconnects due to unknown reason, the mesh system will determine another accessible AP and transfer the packets to that AP.

 Maintain a certain degree of normal operation for it is not easily affected by connection

interference or terrain blocking of walls or floors.

 For the mesh network system adopts the mesh topology, each node in the network not only

has a single connection but also interweaves to other nodes like a net. Because of such characteristics, the mesh network can set up stronger network architecture.

 Each node (mesh AP) in the mesh network can be operated as an independent wireless AP;

therefore, the whole mesh network can offer a more stable and faster wireless connection.

 The mesh network is suitable for large spaces and large numbers of people for the

configuration for each AP is easy and simple.

II-2 General Concepts for Wireless LAN (2.4GHz/5GHz)

VigorAP 912C is a highly integrated wireless local area network (WLAN) for 5 GHz 802.11ac or 2.4/5 GHz 802.11n WLAN applications. It supports channel operations of 20/40 MHz at 2.4 GHz and 20/40/80 MHz at 5 GHz. VigorAP 912C can support data rates up to 867 MBps in 802.11ac 80 MHz channels.

Note:



* The actual data throughput will vary according to the network conditions and environmental factors, including volume of network traffic, network overhead and building materials.

VigorAP 912C plays a role as an Access Point (AP) connecting to lots of wireless clients or Stations (STA). All the STAs will share the same Internet connection via VigorAP 912C. The General Setup will set up the information of this wireless network, including its SSID as identification, located channel etc.

Security Overview

WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via radio using either a 64-bit or 128-bit key. Usually access point will preset a set of four keys and it will communicate with each station using only one out of the four keys.

WPA (Wi-Fi Protected Access), the most dominating security mechanism in industry, is separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK), and WPA-Enterprise or called WPA/802.1x.

In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies AES. The WPA-Enterprise combines not only encryption but also authentication.

Since WEP has been proved vulnerable, you may consider using WPA for the most secure connection. You should select the appropriate security mechanism according to your needs. No matter which security suite you select, they all will enhance the over-the-air data protection and /or privacy on your wireless network. The VigorAP 912C is very flexible and can support multiple secure connections with both WEP and WPA at the same time.

WPS Introduction

WPS (Wi-Fi Protected Setup) provides easy procedure to make network connection between

wireless station and wireless access point (VigorAP 912C) with the encryption of WPA and WPA2.

It is the simplest way to build connection between wireless network clients and VigorAP 912C. Users do not need to select any encryption mode and type any long encryption passphrase to setup a wireless client every time. He/she only needs to press a button on wireless client, and WPS will connect for client and VigorAP 912C automatically.

Note:



Such function is available for the wireless station with WPS supported.

There are two methods to do network connection through WPS between AP and Stations: pressing the Start PBC button or using PIN Code.

On the side of VigorAP 912C series which served as an AP, press WPS button once on the front panel of VigorAP 912C or click Start PBC on web configuration interface. On the side of a station with network card installed, press Start PBC button of network card.

If you want to use PIN code, you have to know the PIN code specified in wireless client. Then provide the PIN code of the wireless client you wish to connect to the VigorAP 912C.

II-3 Wireless LAN (2.4GHz/5GHz) Settings for AP Mode

II-3-9 Airtime Fairness

Airtime fairness is essential in wireless networks that must support critical enterprise applications.

Most of the applications are either symmetric or require more downlink than uplink capacity; telephony and email send the same amount of data in each direction, while video streaming and web surfing involve more traffic sent from access points to clients than the other way around. This is essential for ensuring predictable performance and quality-of-service, as well as allowing 802.11n and legacy clients to coexist on the same network. Without airtime fairness, offices using mixed mode networks risk having legacy clients slow down the entire network or letting the fastest client(s) crowd out other users.

With airtime fairness, every client at a given quality-of-service level has equal access to the network's airtime.

The wireless channel can be accessed by only one wireless station at the same time.

The principle behind the IEEE802.11 channel access mechanisms is that each station has equal probability to access the channel. When wireless stations have similar data rate, this principle leads to a fair result. In this case, stations get similar channel access time which is called airtime.

However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the fast stations (11n) become much slower.

Take the following figure as an example, both Station A(11g) and Station B(11n) transmit data packets through VigorAP 912C. Although they have equal probability to access the wireless channel, Station B(11n) gets only a little airtime and waits too much because Station A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is obstructed by Station A(slow rate).

To improve this problem, Airtime Fairness is added for VigorAP 912C. Airtime Fairness function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the following figure, Station B(11n) has higher probability to send data packets than Station A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by Station A(slow rate).

It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station depends on instant active station number and airtime assignment. Please note that Airtime Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS, this function can reduce the bad influence of slow wireless devices and improve the overall wireless performance.

Suitable environment:

(1) Many wireless stations.

(2) All stations mainly use download traffic.

(3) The performance bottleneck is wireless connection.

Available settings are explained as follows:

Item Description

After finishing this web page configuration, please click OK to save the settings.

Note:



Airtime Fairness function and Bandwidth Limit function should be mutually exclusive. So their webs have extra actions to ensure these two functions are not enabled simultaneously.

II-3-10 Station Control

Station Control is used to specify the duration for the wireless client to connect and reconnect VigorAP. If such function is not enabled, the wireless client can connect VigorAP until it shuts down.

Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job within one hour and will not occupy the wireless network for a long time.

Note:



Up to 300 Wireless Station records are supported by VigorAP.

AP-assisted Client Roaming Parameters

When the link rate of wireless station is too low or the signal received by the wireless station is too worse, VigorAP 912C will automatically detect (based on the link rate and RSSI requirement) and cut off the network connection for that wireless station to assist it to connect another Wireless AP to get better signal.

Minimum Basic Rate – Check the box to use the drop down list to specify a basic rate (Mbps). When the link rate of the wireless station is below such value, VigorAP 912C will terminate the network connection for that wireless station.

Disable RSSI Requirement - If it is selected, VigorAP will not terminate the network connection based on RSSI.

Strictly Minimum RSSI - VigorAP uses RSSI (received signal strength indicator) to decide to terminate the network connection of wireless station. When the signal strength is below the value (dBm) set here, VigorAP 912C will terminate the network connection for that wireless station.

Minimum RSSI - When the signal strength of the wireless station is below the value (dBm) set here and adjacent AP (must be DrayTek AP

and support such feature too) with higher signal strength value (defined in the field of With Adjacent AP RSSI over) is detected by VigorAP 912C, VigorAP 912C will terminate the network connection for that wireless station. Later, the wireless station can connect to the adjacent AP (with better RSSI).

 With Adjacent AP RSSI over – Specify a value as a threshold.

Fast Roaming (WPA2/802.1x)

After finishing this web page configuration, please click OK to save the settings.

cache. PMK Cache manages the list from the BSSIDs in the associated SSID with which it has pre-authenticated. Such feature is available for

WPA2/802.1 mode.

Pre-Authentication - Enables a station to authenticate to multiple

APs for roaming securer and faster. With the pre-authentication procedure defined in IEEE 802.11i specification, the pre-four-way-handshake can reduce handoff delay perceivable by a mobile node. It makes roaming faster and more secure. (Only valid in WPA2)

Enable - Enable IEEE 802.1X Pre-Authentication.

Disable - Disable IEEE 802.1X Pre-Authentication.

II-3-12 Band Steering (for Wireless LAN (2.4GHz))

Band Steering detects if the wireless clients are capable of 5GHz operation, and steers them to that frequency. It helps to leave 2.4GHz band available for legacy clients, and improves users experience by reducing channel utilization.

If dual-band is detected, the AP will let the wireless client connect to less congested wireless LAN, such as 5GHz to prevent from network congestion.

Note:



To make Band Steering work successfully, SSID and security on 2.4GHz also MUST be broadcasted on 5GHz.

Open Wireless LAN (2.4GHz)>>Band Steering to get the following web page:

Available settings are explained as follows:

Item Description

Enable Band Steering If it is enabled, VigorAP 912C will detect if the wireless client is capable

of dual-band or not within the time limit.

Check Time…. – If the wireless station does not have the capability of 5GHz network connection, the system shall wait and check for several seconds (15 seconds, in default) to make the 2.4GHz network connection. Specify the time limit for VigorAP to detect the wireless client.

Wait Full Time to Check 5G Capability – If enabled, the client trying to connect to wireless network 2.4G has to wait for a few seconds (defined in Check Time... above) to check if the connecting device has the 5G capability. If no 5G capability, the client will be directed to the wireless 2.4G network.

5GHz Minimum RSSI – The wireless station has the capability of 5GHz network connection, yet the signal performance might not be satisfied. Therefore, when the signal strength is below the value set here while the wireless station connecting to VigorAP, VigorAP will allow the client to connect to 2.4GHz network.

Overloaded – If it is enabled, VigorAP will activate the band steering according to the conditions set below.

 2.4GHz Utilization Overload Threshold – The default setting is

70%. It can define the network congestion for 2.4GHz.

 5GHz Utilization Overload Threshold – The default setting is

70%. It can define the network congestion for 5GHz.

When the utilization of 2.4GHz is higher than the specified threshold and the utilization of 5GHz is lower than the specified threshold, VigorAP will steer the client to connect to 5GHz network.

After finishing this web page configuration, please click OK to save the settings.

Tips for Mesh Network Setup

 Set up TWO mesh devices with uplink RSSI larger than -65dBm.  Upgrade the firmware version of Mesh devices through Mesh link, starting from the mesh

device with less hop number. For example, upgrade the firmware from the root, hop1 Mesh Node then hop2 Mesh Node, and so on.

 VigorMesh network supports up to 3 hops of mesh devices. However, it is suggested to connect

the mesh group with less than or equals to 2 hops.

For your reference, we make a real mesh environment test and get the following record. (Use VigorAP APP to do internet speed test with different hops mesh node.)

Internet Download Speed (for root and hop1 ~ hop3):

Check the item(s) you want to make configuration sync.

Apply – Click it to apply the settings configured by such AP to all connected mesh node. Note that this button is available only when such AP is in mesh root mode.

iPad connects to hop1 Node : 49Mbps (Uplink RSSI : -55dBm)

iPad connects to hop2 Node : 41Mbps (Uplink RSSI : hop2 -64dBm / hop1 -55dBm)

iPad connects to hop3 Node : 26Mbps (Uplink RSSI : hop3 -62dBm / hop2 -68dBm / hop1

-55dBm)

 It is not suggested to use a wireless Mesh Node with Ethernet cable connected to a Mesh Root.  If resetting a Mesh Root,

- All "connected" Mesh Nodes will be informed to reset.

- Group List and Group Key will be reset, too.

- For those Mesh Nodes unable to reset, reset them manually. Reset the Group List by web

or factory default.

 If resetting a Mesh Node,

- Group List and Group Key will be cleared.

- Link Status will become "New".

 Mesh network status also can be viewed and checked through the dashboard by clicking MESH

NETWORK.

 If Mesh Search / Apply / Discover is worked too fast or is done with empty result, your request

may be rejected. Please try again.

 Troubleshooting:

- Check the firmware version. Please make sure all APs within the mesh group are in the

newest firmware version.

- Check the OP (operation) Mode. Make sure new Mesh Node doesn't accidentally get DHCP

IP and becomes AP mode.

- Check the country code and channels. For example, it is impossible for connecting a

VigorAP 912C Mesh Root with 5G channel 36 to VigorAP920R Wireless Mesh Node in EU country code.

- Check the channel load. Make sure it is not over 70%.

- Collect some Mesh logs and send the result to DrayTek for analyzing.
