Wireless LAN Configuration 7-3
You can then configure:
• Channel: (1 through 11) on which the network will broadcast. This is a frequency range within the 2.4Ghz
band. Channel selection depends on government regulated radio frequencies that vary from region to
region. The widest range available is from 1 to 14. However, in North America only 1 to 11 may be
selected. Europe, France, Spain and Japan will differ. Channel selection can have a significant impact on
performance, depending on other wireless activity close to this Router. Channel selection is not necessary
at the client computers; the clients will scan the available channels seeking access points using the same
SSID as the client.
• Closed System: If you toggle Closed System to Closed, the wireless network is hidden from the scanning
features of wireless client computers. Unless both the wireless clients and the Netopia 3387W-ENT share
the same SSID in Closed System mode, the Netopia 3387W-ENT’s wireless LAN will not appear as an
available network when scanned for by wireless-enabled computers. Members of the Closed System WLAN
must log onto the Netopia 3387W-ENT’s wireless network with the identical SSID as that configured in the
router.
Closed System mode is an ideal way to increase wireless security and to prevent casual detection by
unwanted neighbors, office users, or malicious users such as hackers.
If you toggle it to Open, it is more convenient, but potentially less secure, for clients to access your WLAN
by scanning available access points. You must decide based on your own network requirements.
• Enable WEP: You can provide a level of data security by enabling WEP (Wired Equivalent Privacy) for
encryption of network data. You can enable 40-, 128-, or 256-bit WEP Encryption (depending on the
capability of your client wireless card) for IP traffic on your LAN.
You select a single key for encryption of outbound traffic. The WEP-enabled client must have an identical
key of the same length, in the identical slot (1 – 4) as the Router, in order to successfully receive and
decrypt the traffic. Similarly, the client also has a ‘default’ key that it uses to encrypt its transmissions. In
order for the Router to receive the client’s data, it must likewise have the identical key of the same length,
in the same slot. For simplicity, a Router and its clients need only enter, share, and use the first key.
