encounter severe communication difficulties between the GlobeSurfer 3G
and Wireless-G products.

Beacon interval

A beacon is a packet broadcast by GlobeSurfer 3G to syn-

chronize the wireless network. The beacon interval value indicates how
often the beacon is sent.

DTIM interval

The Delivery Traffic Indication Message (DTIM) is a count-

down value that informs wireless clients of the next opportunity to re-
ceive multicast and broadcast messages. This value ranges between 1
and 16384.

Fragmentation threshold

Packets that are larger than this threshold are frag-

mented into multiple packets. Try to increase the fragmentation thresh-
old if you encounter high packet error rates. Do not set the threshold too
low, since this can result in reduced networking performance.

RTS threshold

GlobeSurfer 3G sends Request to Send (RTS) packets to the

wireless client in order to negotiate the dispatching of data. The wire-
less client responds with a Clear to Send (CTS) packet, signaling that
transmission can commence. In case packets are smaller than the pre-
set threshold, the RTC/CTS mechanism is not active. If you encounter
inconsistent data flow, try a minor reduction of the RTS threshold size.

To configure your wireless security, select the

stations

to allow wireless clients that use standard WEP to communicate

with the gateway. Select

Accept Non-802.1X WEP stations

to allow wireless

clients that use non-standard WEP to communicate with the gateway.

Authentication method

Select the authentication method you would like to

use from the

Authentication method

combo box. Choose between

Pre-

Shared key

and

802.1x

.

Pre-Shared key

This entry appears only if you had selected this authentica-

tion method. Enter your encryption key in the

Pre-Shared key

field. You
