ZyWALL 2 and ZyWALL 2WE

Figure 7-8 RTS Threshold

The RTS Threshold mechanism provides a solution to prevent these data collisions. When you enable RTS Threshold on a possible hidden station, this station and its AP will use a Request to Send/Clear to Send protocol (RTS/CTS). The station send an RTS message to the AP, informing that it is going to transmit the data. Upon receipt, the AP responds with a CTS message to all stations within its range to notify all other stations to defer transmission. It also confirms with the requesting station that the AP has reserved it for the time frame of the requested transmission.

The ZyWALL activates the RTS function if the packet size exceeds the value you set. It is highly recommended that you set the value ranging from 0 to 2432.

Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.

7.6.4Fragmentation Threshold

Fragmentation improves efficiency when high traffic flows along in the wireless network.

7.6.5WEP

As the first line of protection against wireless network intrusion, the ZyWALL provides the standard WEP (Wired Equivalent Privacy) for data encryption. However, there may be a significant degradation of the data throughput on the wireless link when WEP is enabled. See section 8.3 for more information about configuring WEP data encryption.

7.7Wireless LAN Setup

Use menu 3.5 to set up your ZyWALL as the wireless access point.
