WEP is the wireless LAN security technology 
specified by IEEE802.11. It applies encryption to 
communications to prevent outsiders from 
intercepting communications or intruding into 
your wireless network. There are two types of 
encryption key length: 64-bit key and 128-bit key. 
The 128-bit encryption key assures a higher 
security level. Because many wireless devices 
support WEP conventionally, WEP has high 
compatibility. However, a decryption technique 
exists, so using the same encryption key for an 
extended period of time is not recommended.

z

TKIP is a security technology developed to 
correct for the deficiencies of WEP.

z

AES is a security technology which uses an 
advanced encryption method that is distinct from 
WEP and TKIP. AES assures a higher security 
level than WEP or TKIP.

z

The security for wireless LAN communication is 
set to [WEP] at the time of purchase. To increase 
the security level, switching to [WPA-PSK 
(TKIP)] or [WPA2-PSK (AES)] is 
recommended, depending on the security 
technology supported by your wireless device.

You need to set the option in accordance with the 
settings of the wireless LAN to which you want 
to connect.

You can select whether to permit or deny access 
to the [Base Station Setting] page from a device 
that has a global IP address.
Usually, only devices that are in the same LAN 
and have a private IP address can access the [Base 
Station Settings] page. However, some routers 
allow you to assign a global IP address to a 
device, and if you do so, the device cannot access 
the [Base Station Settings] page. If you want to 
access the [Base Station Settings] page from a 
device with a global IP address, you need to make 
access control settings as follows.

1

Select this if you want to permit access from 
only devices that have a private IP address.

2

Select this if you want to permit access from 
devices that have a global IP address.

• When security is provided from the Internet side 

(WAN side), make sure it also covers this port 80, 
such as by means of a firewall function on the 
router.

*1

• If security is not provided by the router, there is a 

risk that the Base Station may be accessed via port 
80 by an intruder on the Internet (WAN) side. To 
ensure the security of the Base Station, refer to 
“Changing the Password” (

1 page 31), and change 

the password periodically to prevent an intruder 
from logging in to the [Base Station Settings] 
page.

*2

• If an intruder accesses and logs in to the [Base 

Station Settings] page, the following dangers 
exist:

*3

- The Base Station settings may be changed.
