Item Default Description
Fragmentation
Threshold
2432
This setting determines the size at which packets are
fragmented. Enter a setting ranging from 256 to 2432 bytes.
Use a low setting in areas where communication is poor or
where there is a great deal of radio interference.
Preamble Type Long Preamble
The preamble type is a section of data at the head of a
packet that contains information the Wireless Subscriber
Gateway and client devices need when sending and
receiving packets. The setting menu allows you to select a
long, short or dynamic preamble type.
Authentication
Method
Open System
Select open system, shared Key or both.
Open System—Allows any device to authenticate and then
attempt to communicate with the Wireless Subscriber
Gateway. Using open authentication, any wireless device can
authenticate with the Wireless Subscriber Gateway, but the
device can only communicate if its WEP keys match the
Wireless Subscriber Gateway. Devices not using WEP do not
attempt to authenticate with a Wireless Service Gateway that
is using WEP.
Shared Key—During shared key authentication, the Wireless
Subscriber Gateway sends an unencrypted challenge text
string to any device attempting to communicate with the
Wireless Subscriber Gateway. The device-requesting
authentication encrypts the challenge text and sends it back
to the Wireless Subscriber Gateway. If the challenge text is
encrypted correctly, the Wireless Subscriber Gateway allows
the requesting device to authenticate. Both the unencrypted
challenge and the encrypted challenge can be monitored,
however, which leaves the Wireless Subscriber Gateway
open to attack from an intruder who calculates the WEP key
by comparing the unencrypted and encrypted text strings.
Because of this weakness, shared key authentication can be
less secure than open authentication.
Both—With this setting wireless stations can communicate
with or without data encryption.
