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)

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

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

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.
