information that are used to examine performance and troubleshoot.

4.4.1

Wireless Settings

This function is used to modify the standard 802.11 wireless radio settings. It is recommended not to change the default settings, because incorrect settings may impair

the performance of your wireless radio. The default settings provide the best wireless radio performance in most environments.

the page shown in

the following figure appears.

In this page, you can configure the

parameters of wireless LAN clients that may connect to the device.



Enable Wireless

: Select this to turn Wi-Fi on and off.



Wireless Network Name (SSID)

: The Wireless Network Name is a

unique name that identifies a network. All devices on a network

must share the same wireless network name in order to

communicate on the network. If you decide to change the wireless

network name from the default setting, enter your new wireless

network name in this field.



Visibility Status

: You can select

Visible

or

Invisible

.



Country

: Select the country from the drop-down list.



Wireless Channel

: Select the wireless channel from the pull-down

menu. It is different for different countries.



802.11 Mode

: Select the appropriate 802.11 mode based on the

wireless clients in your network. The drop-down menu options are

802.11n auto, 802.11g only, Mixed 802.11g and 802.11b, or 802.11b

4.4.1.2 Advanced Settings

In the

Wireless Settings

page, click

Advanced settings

,

the page shown in

the following figure appears.



Multicast Rate:

Select the multicast transmission rate for the network.

The rate of data transmission should be set depending on the speed of

your wireless network. You can select from a range of transmission

speeds, or you can select

Auto

to have the Router automatically use the

fastest possible data rate and enable the Auto-Fallback feature.

Auto-Fallback will negotiate the best possible connection speed between

the Router and a wireless client. The default value is

Auto

.



Fragmentation Threshold:

Packets that are larger than this threshold

are fragmented into multiple packets. Try to increase the fragmentation

threshold if you encounter high packet error rates. Do not set the

threshold too low, since this can result in reducing networking

performance.



RTS Threshold:

This value should remain at its default setting of

2347.Should you encounter inconsistent data flow, only minor reductions

are recommended. Should you encounter inconsistent data flow, only

minor reduction of the default value, 2347 is recommended. If a network

packet is smaller than the preset RTS threshold size, the RTS/CTS

mechanism will not be enabled. The Router sends Request to Send

(RTS) frames to a particular receiving station and negotiates the sending

of a data frame. After receiving an RTS, the wireless station responds

with a Clear to Send (CTS) frame to acknowledge the right to begin

transmission. The RTS Threshold value should remain at its default

value of 2347.



DTIM Interval:

(Delivery Traffic Indication Message) Enter a value

between 1 and 255 for the Delivery Traffic Indication Message (DTIM.) A

DTIM is a countdown informing clients of the next window for listening to

broadcast and multicast messages.



Beacon Interval:

A beacon is a packet of information that is sent from a

connected device to all other devices where it announces its availability

and readiness. A beacon interval is a period of time (sent with the

beacon) before sending the beacon again. The beacon interval may be

adjusted in milliseconds (ms).

Default (100) is recommended.



Global Max Clients:

Specifies maximum wireless client stations to be

enble to link with AP. Once the clients exceed the max vlaue, all other

clients will be refused.
