Section 3 - Configuration

WIRELESS SECURITY MODE – WPA-Personal

Use

WPA

or

WPA2

mode to achieve a balance of strong security

and best compatibility. This mode uses WPA for legacy clients while

maintaining a higher level of security with stations that are WPA2

capable. Also the strongest cipher that the client supports will be used.

For best security, use

WPA2 Only

mode. This mode uses AES (CCMP)

cipher and legacy stations are not allowed access with WPA security.

For maximum compatibility, use

WPA Only

. This mode uses TKIP

cipher. Some gaming and legacy devices work only in this mode.

According to the WiFi Alliance 11N specification, Wi-Fi Protected Setup is not

fully supported under WPA Only mode. We will disable your Wi-Fi Protected

Setup if you use WPA Only mode.

Select

Auto(WPA or WPA2)

or

WPA2 only

or

WPA only

on the

WPA Mode

.

Type the value in seconds on the

Group Key Update Interval

. The default value

is 1800.

Section 3 - Configuration

Local Network

You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP

service to manage the IP settings for their private network. The IP address of the router is the base address used for DHCP. In order to use the router

for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the router. The IP addresses available in the

DHCP IP address pool will change automatically if you change the IP address of the router.

To access the

Local Network

settings window, click on

Local Network

in the SETUP directory.

ROUTER SETTINGS

To change the

to 192.168.1.254.

The IP address pool can be up to 253 IP addresses.

Set the

DHCP Lease Time

in number of hours. The default value is 72.

If you don’t want DSL-2740R to be the DHCP server, you can enable

DHCP

relay

to pass the DHCP discover packets of the clients to another DHCP server.

Please set the DHCP server IP address in

DHCP Server IP Address

Time

The

TIME

configuration option allows you to configure, update, and maintain the correct time on the internal system clock. From this section you

can set the time zone that you are in and set the NTP (Network Time Protocol) Server. Daylight Saving can also be configured to automatically

adjust the time when needed.

To access the

TIME

setting window, click on the

drop-

down menu. Or, you can type the specific NTP server name.

Select your operating time zone from the

drop-down menu.

If you need to enable daylight saving time, just select

Enable Daylight

Saving

. Daylight saving is a period from late Spring to early Fall.

Set how many hours to change the time for Daylight saving Offset.

Configure Daylight Saving Dates

Daylight Saving time starts in the most parts of the United States on

the second Sunday of March. Each time zone in the United States

starts Daylight Saving time at 2 A.M. Thus, in the United States, you

should use March, Second, Sunday, at 2:00 A.M for the start time.

Daylight Saving time starts in the European Union on the last Sunday

of March. Thus, in the European Union, you must select March, Last,

Sunday for the start time. The time must depend on your country’s time

zone. For example, in Germany you must type 2 because Germany’s

time zone is 1 hour ahead of GMT or UTC (GMT+1). Thus, in Germany

you should use March, Last, Sunday, at 1:00 A.M for the start time.
