wireless:security [IG Manual]

====== Wireless Security ======
:!: **It is __extremely__ important to protect your wireless network!**

An unprotected wireless network means **anybody** within several hundred meters from you can eavesdrop on your communication, steal your data, credit card numbers, or infect your computers with viruses!

We **strongly** recommend you to use **WPA2** encryption!

The Internet Gate offers several different ways of increasing wireless security:\\

===== Encryption =====
You can select WEP, WPA and WPA2 as **Security** (encryption).

:!: Avoid using WEP as it has //very// weak security! Only use WEP if absolutely necessary, e.g. when connecting legacy clients only capable of WEP.

===== Access Control =====
You can specify exactly which clients are allowed to connect to your Internet Gate.

Specify the MAC address of each allowed client then enable **Access Control** to allow only those clients to connect.

===== Closed System =====
Closed System means your Internet Gate does not appear on clients "Available hosts" list, but must be connected to manually.

===== Café mode =====
Café mode means each client can connect to the Internet Gate and the Internet, but they cannot communicate with each other. Wireless clients A and B can both connect to the Internet, but client A cannot connect to client B.
