The Basic Configuration
1-18
Selecting the Frequency
Although wireless networks can be logically separated by setting
the
network name , they can still physically interfere with each
other if they are operated on the same radio channel or on chan-
nels which are close together.
Consequently, if you operate two or more wireless networks
within short distance, it is advisable to assign different channels to
the networks. Since a network also allocates a part of its adjacent
channels, these channels should be at least 4 channels apart from
each other. You can find further information in
Section Configu-
ration: Wireless, Page 4–10 .
Activating the Encryption
To prevent the data transmitted via radio technology from being
eavesdropped easily, you should activate the encryption. In the
process, the same key will be entered at all stations or clients of a
wireless network. Basically, there are two key lengths: 64 bits (cor-
responds to a 40-bit-effective key) and 128 bits (corresponds to a
104-bit-effective key). If all clients used support 128-bit encryp-
tion, you should activate it. For a detailed description, see
Section
Configuration: Security, Page 4–14 .
