Chapter I Installation

I-1 Introduction

This is a generic International version of the user guide. Specification, compatibility and features vary by

region. For specific user guides suitable for your region or product, please contact local distributor.

Thank you for purchasing this VigorAP 903, the concurrent dual band wireless (2.4G/5G) access point

offering high-speed data transmission. With this high cost-efficiency VigorAP 903, computers and wireless

devices which are compatible with 802.11n/802.11a can connect to existing wired Ethernet network via

this VigorAP 903, at the speed of 300Mbps.

Easy install procedures allows any computer users to setup a network environment in very short time -

within minutes, even inexperienced users. Just follow the instructions given in this user manual, you can

complete the setup procedure and release the power of this access point all by yourself!

VigorAP 903 also is a Power over Ethernet Powered Device which adopts the technology of PoE for offering

power supply and transmitting data through the Ethernet cable.

AP Management

The VigorAP 903 can operate in standalone mode for your office network or a classroom or a waiting room

of some transportation terminals (e.g. ferry terminal, bus station, train station) or a clinic's waiting room ;

connected to your LAN and offering you with wireless access. If your network requires several VigorAP 903

units, to centrally manage and monitor them individually as a group will be expected. DrayTek central

wireless management (AP Management) lets control, efficiency, monitoring and security of your

company-wide wireless access easier be managed. Inside the web user interface, we call “central wireless

management” as Central AP Management which supports mobility, client monitoring / reporting and

load-balancing to multiple APs. For central wireless management, you will need a Vigor2860 or Vigor2925

series router; there is no per-node licensing or subscription required. With the unified user interface of

Vigor2860 Combo WAN series and Vigor2925 Triple WAN series, the multiple deployment of VigorAP 903

can be clear at the first sight. For multiple wireless clients to apply the AP Load Balancing to the multiple

APs, AP management will manage wireless traffic with smooth flow and enhanced efficiency.

Support Mesh Network

The message, information, and data can be transferred via wireless connection among VigorAP 903

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 903 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 903 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 903 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 903. 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 903 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 903) with the encryption of WPA and WPA2.

It is the simplest way to build connection between wireless network clients and VigorAP 903. 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 903 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 903 series which served as an AP, press WPS button once on the front panel of

VigorAP 903 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 903.

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

When you choose AP as the operation mode, the Wireless LAN menu items will include General Setup,

(Simulate 2 APs)

Check the box to enable the function for two independent subnets. Once

you enable this function, LAN-A and LAN-B would be independent. Next,

you can connect one router in LAN-A, and another router in LAN-B. Such

mechanism can make you feeling that you have two independent

AP/subnet functions in one VigorAP 903.

If you disable this function, LAN-A and LAN-B ports are in the same

domain. You could only connect one router (no matter connecting to

LAN-A or LAN-B) in this environment.

Hide SSID Check it to prevent from wireless sniffing and make it harder for

unauthorized clients or STAs to join your wireless LAN. Depending on the

wireless utility, the user may only see the information except SSID or just

cannot see any thing about VigorAP 903 while site surveying. The system

allows you to set four sets of SSID for different usage.

SSID Set a name for VigorAP 903 to be identified. Default settings are

DrayTek-LAN-A and DrayTek-LAN-B. When Enable 2 Subnet is enabled,

you can specify subnet interface (LAN-A or LAN-B) for each SSID by using

the drop down menu.

Subnet Choose LAN-A or LAN-B for each SSID. If you choose LAN-A, the wireless

clients connecting to this SSID could only communicate with LAN-A.

Isolate Member Check this box to make the wireless clients (stations) with the same SSID

not access for each other.

VLAN ID Type the value for such SSID. Packets transferred from such SSID to LAN

will be tagged with the number.

If your network uses VLANs, you can assign the SSID to a VLAN on your

network. Client devices that associate using the SSID are grouped into this

VLAN. The VLAN ID range is from 3 to 4095. The VLAN ID is 0 by default, it

means disabling the VLAN function for the SSID.

PHY Mode Data will be transmitted via HTMIX mode.

Each access point should be setup to the same Phy Mode for

connecting

with each other.

Subnet Choose LAN-A or LAN-B for each SSID.

A remote AP should use LAN-A to connect to VigorAP 903 via WDS.

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 903. 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 903. 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

Enable Airtime

Fairness

Try to assign similar airtime to each wireless station by controlling TX

traffic.

Airtime Fairness – Click the link to display the following screen of airtime

fairness note.

Triggering Client Number –Airtime Fairness function is applied only

when active station number achieves this number.

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.

II-3-11 Roaming

The network signal for a single wireless access point might be limited by its coverage range. Therefore, if

you want to expand the wireless network in a large exhibition with a quick method, you can install multiple

access points with enabling the Roaming feature for each AP to reach the purpose of expanding wireless

signals seamlessly.

These access points connecting for each other shall be verified by pre-authentication. This page allows you

to enable the roaming feature and the pre-authentication.

Available settings are explained as follows:

Item Description

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 903 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 903 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 903 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 903,

VigorAP 903 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)

Enable – Check the box to enable fast roaming configuration.

PMK Caching - Set the expire time of WPA2 PMK (Pairwise master key)

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.

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):

iPad connects to Root : 80Mbps

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 903

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.
