Wireless Security
Wireless transmissions are easier to intercept than transmissions over a wired network.
Therefore use of security is highly recommended. Basic wireless security provided two
methods of implementing security. They are SSID and WEP.
SSID (Service Set Identifier) – Much like a password, this is a unique name shared
among all points in a wireless network. The SSID must be identical at each point in the
wireless network. It is case sensitive and may consist of any character on your
keyboard. Choose an SSID that is more secure, preferably using a combination of
letters and numbers. SSID Broadcast should be disabled.
WEP (Wired Equivalent Privacy) – Enabling Wired Equivalent Privacy (WEP) on
the wireless devices requires you to enter a WEP key (or a passphrase that will generate
a Key). Valid WEP keys are 64 and 128 bit for Linksys products and 40-bit and 128-bit
for the wireless serial server. WEP setting must be identical to all wireless points on
your network. Both Linksys and the GW21W-MAXI support 128-bit therefore we
recommend you use 128-bit on your wireless G2 network. For all Linksys products, a
passphrase can be entered and a key automatically generated. For Wireless Serial
Servers, only a key may be entered. If you generate a 128-bit key from a passphrase,
write down the key so that you may later enter it into your Wireless Serial Server.
When choosing a WEP passphrase, use one that is secure, preferably using a
combination of letters and numbers.
