Channels
The Wireless Channel sets the radio frequency used for communication.
•
Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available.
•
Client (PC) Wireless Stations normally scan all Channels, looking for an Access Point. If
more than one Access Point can be used, the one with the strongest signal is used. (This
can only happen within an ESS.)
•
If your PC's wireless card does NOT automatically scan all wireless channels, then you
must manually set it to the Channel used on the Access Point.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless
the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same settings
for each of the following:
WEP
Off, 64 Bit, 128 Bit
Key
For 64 Bit encryption, the Key Table must match.
For 128 Bit encryption, the Key value must match.
WEP Authentication
Open System or Shared Key.
