Note:

Before configuring WDS, please ensure the following first:

1. Make sure different IP addresses are assigned to each WDS supported wireless device

used for bridging. (ex. 192.168.10.1,192.168.10.2, 192.168.10.3) to avoid IP address

conflict. See page 34 for changing the LAN IP address.

2. If you are using more than one WDS supported router, please make sure the LAN

DHCP server is enabled on only one and disabled on all others to avoid IP address

conflict. See page 35 for DHCP server options.

3. Configure the same wireless channel and use the same on all WDS supported wireless

devices. See page 20 for configuring basic wireless settings.

4. Configure the same wireless security and key on all WDS supported devices. See page

15 for configuring wireless security settings.

To configure WDS bridging between TEW-811DRU routers:

1. Log into your router management page (see “

Access your router management page

”

on page 31).

2. Click on

Wireless (2.4GHz

5GHz

)

and click on

Basic

3. Next to

Wireless Distribution System (WDS)

, in an empty field, enter the MAC

address of the other WDS supported wireless device you are bridging. (e.g.

00:11:22:AA:BB:CC)

4. To save changes, click

Apply

Note:

If you would like to discard the changes, click

Cancel

before you click

Save

For additional routers, make sure to disable the DHCP server first on all additional

routers and configure the LAN IP address to be different on each router. You will

connect devices to the LAN ports 1-4 only on all additional routers and the WAN port is

not used. Then, repeat the steps for additional routers you are bridging.

In the diagram below, the blue color represents the WDS wireless bridged connections

between the routers. The green color represents access point mode connections

between wireless client devices and the routers.

Additional wireless settings

Wireless (2.4GHz or 5GHz) > Advanced

These settings are advanced options that can be configured to change advanced

wireless broadcast specifications. It is recommended that these settings remain set to

their default values unless you are knowledgeable about the effects of changing these

values. Changing these settings incorrectly can degrade performance.

•

Beacon Interval:

A beacon is a management frame used in wireless networks

that transmitted periodically to announce the presence and provide

information about the router’s wireless network. The interval is the amount

time between each beacon transmission.

Default Value: 100 milliseconds (range: 25-1000)

•

DTIM:

A DTIM is a countdown informing clients of the next window for

listening to broadcast and multicast messages. When the wireless router has

buffered broadcast or multicast messages for associated clients, it sends the

next DTIM with a DTIM Interval value. Wireless clients detect the beacons and

awaken to receive the broadcast and multicast messages. The default value is

1. Valid settings are between 1 and 255.

•

Fragment Threshold:

Wireless frames can be divided into smaller units

(fragments) to improve performance in the presence of RF interference and at

the limits of RF coverage. Fragmentation will occur when frame size in bytes is

greater than the Fragmentation Threshold. This setting should remain at its

default value of 2346 bytes. Setting the Fragmentation value too low may

result in poor performance.

•

RTS Threshold:

The Request To Send (RTS) function is part of the networking

protocol. A wireless device that needs to send data will send a RTS before

sending the data in question. The destination wireless device will send a

response called Clear to Send (CTS). The RTS Threshold defines the smallest

data packet size allowed to initiate the RTS/CTS function.

Default Value: 2347 (range: 1-2347)

•

Short Preamble:

Using a short (400ns) guard interval can increase throughput.

However, it can also increase error rate in some installations, due to increased

sensitivity to radio-frequency reflections. Select the option that works best for

your installation.

•

Xpress™ Technology:

A frame bursting technology used to improve wireless

performance. The feature will only work with other Xpress™ supported devices.

It is recommended to leave this feature On.

Access Control Filters

Access control basics

MAC Address Filters

Wired LAN MAC Address Filters

Advanced > Filter

Every network device has a unique, 12-digit MAC (Media Access Control) address. Using

MAC filters, you can allow or deny specific computers and other devices from using this

router’s wired network.

1. Log into your router management page (see “

Access your router management page

”

on page 31).

2. Click on

Advanced

, click on

Filter.

3. Add the MAC addresses to the MAC Table first before applying the MAC filter

function. Next to

LAN MAC Filters

, in an empty field, enter the MAC address of the

devices you would like to filter. (e.g.

00:11:22:AA:BB:CC)

Note:

MAC filter can be configured to allow access to the listed MAC address and deny

all others unlisted or vice versa. The recommended function is to choose to only allow

access to the MAC addresses listed and deny all others unlisted because it is easier to

determine the MAC addresses of devices in your network then to determine which MAC

addresses you do not want to allow access.

Note:

You can check the DHCP Client List for the MAC addresses of the devices on your

network, see page 56 or refer to your computer or device documentation to find the

MAC address.

4. Click on the

LAN MAC Filter Mode

Note:

Do not configure this setting until you have added the MAC addresses to the MAC

Table first. The recommended option is to only

Allow

access to the MAC addresses listed

and deny all others unlisted.

5. To save changes, click
